Aviation career

First flight 1899 (disputed)

Gustave Albin Whitehead, born Gustav Albin Weisskopf (1 January 1874 – 10 October 1927) was an aviation pioneer who emigrated from Germany to the U.S., where he designed and built early flying machines and engines meant to power them from about 1897 to 1915. Whitehead claimed to have flown several times in his own powered aircraft designs in 1901 and 1902, before the Wright brothers flew in 1903. These claims, though supported by researchers in the 1930s and later,[note 2] have been examined and dismissed by mainstream aviation historians, especially those associated with the Smithsonian Institution.[note 3]

During his period of active aeronautical work, Whitehead attracted notice from various newspapers, Scientific American magazine, and a book about industrial progress. Claims for Whitehead's best-known reported manned powered flights depend largely on a newspaper article that said he achieved the feat in Connecticut in August 1901, and on an unsigned Scientific American article in September 1903 describing Whitehead making short flights low to the ground in a motorized triplane originally designed as a glider. Affidavits from people who knew Whitehead or lived nearby were collected more than 30 years later; many of these asserted that Whitehead had flown, though some denied it. No photograph showing Whitehead making a powered flight has ever been found. Aviation historian Charles Harvard Gibbs-Smith dismisses the August 1901 newspaper article as "juvenile fiction".

After his aeronautical experiments of the early 1900s, Whitehead faded from public view until a 1935 magazine article and a 1937 book focused attention on his life and work. In the years afterward "lively debate"[1] arose among scholars, researchers, aviation enthusiasts and even Orville Wright on the question of whether Whitehead preceded the Wright brothers in powered flight. Research in the 1960s and 70s, and pro-Whitehead books in 1966 and 1978, led to renewed examination of the claims by mainstream aviation historians.[2] Following a year of senior scholarship at the National Air and Space Museum, Gibbs-Smith concluded in 1970 that the Whitehead claims to first powered flight were false. Nevertheless, enthusiasts in the U.S. and Germany built and flew near-replicas of Whitehead's 1901 flying machine beginning in the 1980s, using modern engines.[3]


  Early life and career

  Gustave Whitehead with an early engine

Whitehead was born in Leutershausen, Bavaria, the second child of Karl Weisskopf and his wife Babetta. As a boy, he showed an interest in flight, experimenting with kites and earning the nickname "the flyer". He and a friend caught and tethered birds in an attempt to learn how they flew, an activity which police soon stopped. His parents died in 1886 and 1887, when he was a boy. He then trained as a mechanic and traveled to Hamburg, where in 1888 he was forced to join the crew of a sailing ship. A year later, he returned to Germany, then journeyed with a family to Brazil. He went to sea again for several years, learning more about wind, weather and bird flight.[4]

Weisskopf arrived in the U.S. in 1893.[5] He soon anglicized his name to Gustave Whitehead. In 1897, the Aeronautical Club of Boston hired Whitehead to build two gliders. One of which (patterned after a Lilienthal glider) was partially successful and in which Whitehead flew short distances, and toy manufacturer E. J. Horsman in New York hired Whitehead to build and operate advertising kites and model gliders. Whitehead occupied himself with plans to provide a motor to drive one of his gliders.[6]

  Flight claims

  Pittsburgh 1899

According to an affidavit given in 1934 by Louis Darvarich, a friend of Whitehead, the two men made a motorized flight together of about half a mile in Pittsburgh's Schenley Park in April or May 1899. Darvarich said they flew at a height of 20 to 25 ft (6.1 to 7.6 m) in a steam-powered monoplane aircraft and crashed into a brick building. Darvarich said he was stoking the boiler aboard the craft and was badly scalded in the accident, requiring several weeks in a hospital.[7] Reportedly because of this incident, Whitehead was forbidden by the police to perform any more experiments in Pittsburgh.[6] Aviation historian William F. Trimble, pointing to a lack of contemporary proof, dismissed this story in 1982 as a case of "overactive imaginations."[8] Whitehead's stated control method – a shifting of body weight – was said by Trimble to be insufficient to control a powered aircraft, and the supposed charcoal-fired steam powerplant could not have been strong enough to lift itself off the ground.[8]

Whitehead and Darvarich traveled to Bridgeport, Connecticut to find factory jobs.[9]

  Connecticut 1901

The aviation event for which Whitehead is now best-known reportedly took place in Fairfield, Connecticut on 14 August 1901. An unsigned article written as an eyewitness report in the Bridgeport Herald newspaper said Whitehead piloted his Number 21 aircraft in a controlled powered flight for about half a mile up to 50 feet (15 m) high and landed safely.[10][note 4] The feat, if true, preceded the Wright brothers by more than two years and exceeded their best 1903 Kitty Hawk flight, which covered 852 feet (260 m) at a height of about 10 feet (3.0 m). The article about Whitehead is widely attributed to journalist Dick Howell. [11][12]

The Bridgeport Herald, a weekly Sunday newspaper, published the article on 18 August 1901. No photograph was taken of the aircraft in flight. The article was accompanied by a drawing, also credited by some Whitehead researchers to Howell, which depicted the aircraft in flight. Information from the article was also reprinted in the New York Herald, Boston Transcript and The Washington Times, which ran it on 23 August 1901. Over the next few months, the story ran in nine other American newspapers, some as far away as California and Arizona.[13]

  The drawing which accompanied the article in the 18 August 1901, Sunday Herald

The Bridgeport Herald reported that Whitehead and another man drove to the testing area in the machine, which worked like a car when the wings were folded along its sides. Two other people, including the newspaper reporter, followed on bicycles. For short distances the Number 21's speed was close to thirty miles an hour on the uneven road, and the article said, "there seems no doubt that the machine can reel off forty miles an hour and not exert the engine to its fullest capacity.".[10]

The newspaper reported that before attempting to pilot the aircraft, Whitehead successfully test flew it unmanned in the pre-dawn hours, using tether ropes and sandbag ballast. When Whitehead was ready to make a manned flight, the article said: "By this time the light was good. Faint traces of the rising sun began to suggest themselves in the east."[10]

The newspaper reported that trees blocked the way after the flight was in progress, and quoted Whitehead as saying, "I knew that I could not clear them by rising higher, and also that I had no means of steering around them by using the machinery."[10] The article said Whitehead quickly thought of a solution to steer around the trees:

"He simply shifted his weight more to one side than the other. This careened the ship to one side. She turned her nose away from the clump of sprouts when within fifty yards of them and took her course around them as prettily as a yacht on the sea avoids a bar. The ability to control the air ship in this manner appeared to give Whitehead confidence, for he was seen to take time to look at the landscape about him. He looked back and waved his hand exclaiming, 'I've got it at last.'"[10]

  Junius Harworth helped Whitehead with his aircraft

When Whitehead neared the end of a field, the article said he turned off the motor and the aircraft landed "so lightly that Whitehead was not jarred in the least."[10]

Junius Harworth, who was a boy when he was one of Whitehead's helpers, said Whitehead flew the airplane at another time in the summer of 1901 from Howard Avenue East to Wordin Avenue, along the edge of property belonging to the local gas company. Upon landing, Harworth said, the machine was turned around and another hop was made back to the starting point.[14]

On 19 November 1901, the The Evening World (New York), ran a story about Whitehead's achievements and included a photograph of him sitting on his new flying machine. In it, he is quoted; "within a year people will be buying airships as freely as they are buying automobiles today and the sky will be dotted with figures skimming the air".[13]

Before his reported 14 August flight, Whitehead was quoted in a 26 July article in the Minneapolis Journal, credited to the New York Sun, in which he described the first two unmanned trial flights of his machine on 3 May. Andrew Cellie and Daniel Varovi were mentioned as his financial backers and assisted with the flights. The machine carried 220 pounds of sand as ballast and flew to an altitude of 40 to 50 feet for an 1/8 of a mile (201 metres (659 ft)). According to Whitehead, the machine flew a distance of 1/2 mile (805 metres (2,641 ft)) for one and one-half minutes during its second test flight before crashing into a tree. He also explained his desire to keep the location of any future experiments hidden to avoid drawing a crowd who might make a "snap-shot verdict of failure". [13]

During this period of activity, Whitehead also reportedly tested an unmanned and unpowered flying machine, towed by men pulling ropes. A witness said the craft rose above telephone lines, flew across a road and landed undamaged. The distance covered was later measured at approximately 1,000 ft (305 m).[14]

  Connecticut 1902

Whitehead claimed two spectacular flights on 17 January 1902 in his improved Number 22, with a 40 hp (30 kW) motor instead of the 20 hp (15 kW) used in the Number 21, and aluminum instead of bamboo for structural components. In two published letters he wrote to American Inventor magazine,[15] Whitehead said the flights took place over Long Island Sound. He said the distance of the first flight was about two miles (3 kilometers) and the second was seven miles (11 km) in a circle at heights up to 200 ft (61 m). He said the airplane, which had a boat-like fuselage, landed safely in the water near the shore.[15]

For steering, Whitehead said he varied the speed of the two propellers and also used the aircraft rudder. He said the techniques worked well on his second flight and enabled him to fly a big circle back to the shore where his helpers waited. He expressed pride in the accomplishment: "...as I successfully returned to my starting place with a machine hitherto untried and heavier than air, I consider the trip quite a success. To my knowledge it is the first of its kind. This matter has so far never been published."[15]

In his first letter to American Inventor, Whitehead said, "This coming Spring I will have photographs made of Machine No. 22 in the air."[15] He said snapshots, apparently taken during his claimed flights of 17 January 1902 "did not come out right" because of cloudy and rainy weather.[15] The magazine editor replied that he and readers would "await with interest the promised photographs of the machine in the air," but there were no further letters nor any photographs from Whitehead.[15]

A description of a Whitehead aircraft as remembered 33 years later by his brother John Whitehead gave information related to steering:

"Rudder was a combination of horizontal and vertical fin-like affair, the principle the same as in the up-to-date airplanes. For steering there was a rope from one of the foremost wing tip ribs to the opposite, running over a pulley. In front of the operator was a lever connected to a pulley: the same pulley also controlled the tail rudder at the same time." [16]

John Whitehead arrived in Connecticut from California in April 1902, intending to help his brother. He did not see any of his brother's aircraft in powered flight.[16]

A 1935 article in Popular Aviation magazine, which renewed interest in Whitehead, said winter weather ruined the Number 22 airplane after Whitehead placed it unprotected in his yard following his claimed flights of January 1902. The article said Whitehead did not have money to build a shelter for the aircraft because of a quarrel with his financial backer. The article also reported that in early 1903 Whitehead built a 200 horsepower eight-cylinder engine, intended to power a new aircraft. Another financial backer insisted on testing the engine in a boat on Long Island Sound, but lost control and capsized, sending the engine to the bottom.[9]


A full-page article in the 19 September 1903 Scientific American told of Whitehead making powered flights. He first made a series of cautious experiments in a triplane glider towed against the wind by an assistant pulling a rope. He then replaced the assistant with a 54-pound (24 kg) two-cycle motor powering a two-blade propeller that was 4.5 ft (1.4 m) in diameter. The propeller was mounted on the motor's crankshaft in a tractor configuration to pull the aircraft forward rather than push it from behind. The motor was described as capable of generating 12 horsepower (8.9 kW) when operated at 2,500 rpm, but Whitehead throttled it back to 1,000 rpm in his flight experiments. "By running with the machine against the wind after the motor had been started, the aeroplane was made to skim along above the ground at heights of from 3 to 16 feet for a distance, without the operator touching, of about 350 yards. It was possible to have traveled a much longer distance, without the operator touching terra firma, but for the operator's desire not to get too far above it. Although the motor was not developing its full power, owing to the speed not exceeding 1,000 R.P.M., it developed sufficient to move the machine against the wind."[17] The engine shown in the September 1903 article was the engine exhibited by Whitehead at the Second Annual Exhibit of the Aero Club of America in December 1906 that was shown in the photo between the Curtiss and Wright engines.[18]


Whitehead attended the St. Louis World's Fair in 1904 and displayed an aeronautical motor.[19] His work with the "Aeroplane" was included in the book, Modern Industrial Progress, released in late 1904 by Charles Henry Cochrane. The book described Whitehead as one of the "latest of the enthusiasts in the soaring field" who had devised several "soaring apparatuses". Cochrane said Whitehead's "plane" used a "four-sided rudder" for steering and a 12 horsepower motor.[20]

Cochrane also wrote that the Wright brothers made the first successful flight in a powered aircraft without the use of a gas-bag or balloon, outdoing all the other soarers and gliders to date. He went on to say that he hoped that there would not be a delay in the development of the airplane due to patent disputes or quarrels over who invented this or that.[20]

Whitehead's Number 21 monoplane had a wingspan of 36 ft (11 m). The fabric covered wings were ribbed with bamboo, supported by steel wires and were very similar to the shape of the Lilienthal glider's wings. The arrangement for folding the wings also closely followed the Lilienthal design. The craft was powered by two engines: a ground engine of 10 hp (7.5 kW), intended to propel the front wheels to reach takeoff speed, and a 20 hp (15 kW) acetylene engine powering two propellers, which were designed to counter-rotate for stability.

Whitehead described his No. 22 aircraft and compared some of its features to the No. 21 in a letter he wrote to the editor of American Inventor magazine, published 1 April 1902. He said the No. 22 had a five-cylinder 40 hp kerosene motor of his own design, weighing 120 lbs. He said ignition was "accomplished by its own heat and compression."[16] He described the aircraft as 16 feet (4.9 m) long, made mostly of steel and aluminum with wing ribs made of steel tubing, rather than bamboo, which was used in the Number 21 aircraft. He explained that the two front wheels were connected to the kerosene motor, and the rear wheels were used for steering while on the ground. He said the wing area was 450 square feet (42 m2), and the covering was "the best silk obtainable."[16] The propellers were "6 feet in diameter...made of wood...covered with very thin aluminum sheeting."[16] He said the tail and wings could all be "folded up...and laid against the sides of the body."[16]

In 1905, he filed for a patent – issued 1908 – for an "improved aeroplane" with a V-shaped trough body and fixed bird-like wings, the pilot hanging below supported by a swing seat.[22][23] This unpowered design was a hang glider not too different from the ones flown by Otto Lilienthal a decade before.[24] Whitehead also built gliders until about 1906 and was photographed flying them.

  Later career

In addition to his work on flying machines, Whitehead built engines.[25] Air Enthusiast wrote: "In fact, Weisskopf's ability and mechanical skill could have made him a wealthy man at a time when there was an ever-increasing demand for lightweight engines, but he was far more interested in flying."[14] Instead, Whitehead only accepted enough engine orders to sustain aviation experiments.[14]

Whitehead's business practices were unsophisticated and he was sued by a customer, resulting in a threat that his tools and equipment would be seized. He hid his engines and most of his tools in a neighbor's cellar and continued his aviation work. One of his engines was installed by aviation pioneer Charles Wittemann in a helicopter built by Lee Burridge of the Aero Club of America, but the craft failed to fly.[26]

Whitehead's own 1911 studies of the vertical flight problem resulted in a 60-bladed helicopter, which, unmanned, lifted itself off the ground.[9]

He lost an eye in a factory accident and also suffered a severe blow to the chest from a piece of factory equipment, an injury that may have led to increasing attacks of angina. Despite these setbacks he exhibited an aircraft at Hempstead, New York, as late as 1915. He continued to work and invent. He designed a braking safety device, hoping to win a prize offered by a railroad. He demonstrated it as a scale model but won nothing. He constructed an "automatic" concrete-laying machine, which he used to help build a road north of Bridgeport. These inventions, however, brought him no more profit than did his airplanes and engines.[27] Around 1915 Whitehead worked in a factory as a laborer and repaired motors to support his family.[28]

With World War I came prejudice against Germans. Whitehead never lost his German accent and never acquired American citizenship.[29]

He died of a heart attack, on 10 October 1927, after attempting to lift an engine out of an automobile he was repairing. He stumbled onto his front porch and into his home, then collapsed dead in the house.[26]


Whitehead's work remained almost completely unknown to the public and aeronautical community after 1911 until a 1935 article in Popular Aviation magazine co-authored by Stella Randolph, an aspiring writer, and aviation history buff Harvey Phillips.[9] Randolph expanded the article into a book, "Lost Flights of Gustave Whitehead," published in 1937. Randolph sought out people who had known Whitehead and had seen his flying machines and engines. She obtained 16 affidavits from 14 people and included the text of their statements in the book. Four people said they did not see flights, while the others said they saw flights of various types, ranging from a few dozen to hundreds of feet to more than a mile.

Harvard University economics professor John B. Crane wrote an article published in National Aeronautic Magazine in December 1936, disputing claims and reports that Whitehead flew. The following year, after further research, Crane adopted a different tone. He told reporters, "There are several people still living in Bridgeport who testified to me under oath, they had seen Whitehead make flights along the streets of Bridgeport in the early 1900s."[30] Crane repeated Harworth's claim of having witnessed a one-and-a-half mile airplane flight made by Whitehead on 14 August 1901.[30] He suggested a Congressional investigation to consider the claims.[30] In 1949 Crane published a new article in Air Affairs magazine that supported claims that Whitehead flew.[31]

In 1963, William O'Dwyer, a reserve U.S. Air Force major, accidentally discovered photographs of a 1910 Whitehead "Large Albatross"-type biplane aircraft shown at rest on the ground. He found the photo collection in the attic of a Connecticut house. He and members of his 9315th U.S. Air Force Reserve Squadron were requested by the Connecticut Aeronautical Historical Association (CAHA) to conduct research to try to learn if Whitehead had made powered flights.[32] O'Dwyer continued his research for years and became convinced that Whitehead did fly before the Wright brothers. O'Dwyer later contributed to a second book by Stella Randolph, The Story of Gustave Whitehead, Before the Wrights Flew, published in 1966. They also co-authored another book, History by Contract, published in 1978, which criticized the Smithsonian Institution for inadequately investigating claims that Whitehead flew.

In 1968, Connecticut officially recognized Whitehead as "Father of Connecticut Aviation".[33] Seventeen years later, the North Carolina General Assembly passed a resolution which repudiated the Connecticut statement and gave "no credence" to the assertion that Whitehead was first to fly, citing "leading aviation historians and the world's largest aviation museum" who determined there was "no historic fact, documentation, record or research to support the claim".[34]



The most prominent witness statement came from the journalist from the Bridgeport Herald who described how he witnessed the preparations during the night and the first flight early in the morning of 14 August 1901. The article was published on 18 August 1901, and named two witnesses to Whitehead's reported early morning flight, Andrew Cellie and James Dickie. Some sources attribute the article in the Bridgeport Herald, published without a byline, to (Richard) Dick Howell.

Decades later, Dickie denied seeing a flight. He said in a 1937 affidavit, taken during Stella Randolph's research, that he was not present at the reported flight on 14 August 1901, and that he thought the newspaper story was "imaginary".[35] He said he did not know Andrew Cellie, the other associate of Whitehead who was supposed to be there, and that none of Whitehead's aircraft ever flew, to the best of his knowledge.[35] An article in Air Enthusiast countered by saying that the description Dickie gave of the airplane did not match Whitehead's Number 21.[14]

O'Dwyer had known the older Dickie since childhood. Early in his research, O'Dwyer spoke by telephone to Dickie. O'Dwyer learned that Dickie had a grudge against Whitehead. O'Dwyer described the conversation:

"...his mood changed to anger when I asked him about Gustave Whitehead. He flatly refused to talk about Whitehead, and when I asked him why, he said: 'That SOB never paid me what he owed me. My father had a hauling business and I often hitched up the horses and helped Whitehead take his airplane to where he wanted to go. I will never give Whitehead credit for anything. I did a lot of work for him and he never paid me a dime.'"[27]

O'Dwyer said he thought Dickie's 1937 affidavit had "little value." He said there were inconsistencies between the affidavit and his interview with Dickie.[27]

The other man who the Bridgeport Herald named as an eyewitness to the reported flight on 14 August 1901 was Andrew Cellie, but he could not be found in the 1930s when Randolph investigated. O'Dwyer said that in the 1970s he searched through old Bridgeport city directories and concluded that the newspaper likely misspelled the man's name, which he said was Andrew Suelli, who was a Swiss or German immigrant also known as Zulli, and was Whitehead's next door neighbor before moving to the Pittsburgh area in 1902.[36] Suelli's former neighbors in Fairfield told O'Dwyer that Suelli, who died before O'Dwyer investigated, had "always claimed he was present when Whitehead flew in 1901."[27]

Junius Harworth and Anton Pruckner, who sometimes helped or worked for Whitehead, gave statements decades later as part of Stella Randolph's research, claiming they saw Whitehead fly on 14 August 1901.

Anton Pruckner, a tool maker who worked a few years with Whitehead, attested in 1934 to the flight.[14] He also attested to a January 1902 flight by Whitehead over Long Island Sound,[37] but the 1988 Air Enthusiast article said "Pruckner was not present on the occasion, though he was told of the events by Weisskopf himself."[14]

In his first letter to American Inventor, Whitehead claimed he made four "trips" in the airplane on 14 August 1901; and that the longest was one and a half miles.[15]

Discrepancies in statements by witnesses about different flights they said they saw on 14 August 1901, raised questions whether any flight was made. The Bridgeport Sunday Herald reported a half mile flight occurred early in the morning on 14 August. Whitehead and Harworth later claimed that a flight one and a half miles long was made that day.

Among the affidavits collected by Stella Randolph are these, quoted in part:

Affidavit: Joe Ratzenberger – 28 January 1936:
"I recall a time, which I think was probably July or August of 1901 or 1902, when this plane was started in flight on the lot between Pine and Cherry Streets. The plane flew at a height of about twelve feet from the ground, I should judge, and traveled the distance to Bostwick Avenue before it came to the ground."[38]
Affidavit: Thomas Schweibert – 15 June 1936:
"I... recall seeing an airplane flight made by the late Gustave Whitehead approximately thirty-five years ago. I was a boy at the time, playing on a lot near the Whitehead shop on Cherry Street, and recall the incident well as we were surprised to see the plane leave the ground. It traveled a distance of approximately three hundred feet, and at a height of approximately fifteen feet in the air, to the best of my recollection."[39]
Affidavit by Junius Harworth – 21 August 1934:
"On August, fourteenth, Nineteen Hundred and One I was present and assisted on the occasion when Mr. Whitehead succeeded in flying his machine, propelled by a motor, to a height of two hundred feet off the ground or sea beach at Lordship Manor, Connecticut. The distance flown was approximately one mile and a half".[40]

O'Dwyer organized a survey of surviving witnesses to the reported Whitehead flights. Members of the Connecticut Aeronautical Historical Association (CAHA) and the 9315th Squadron (O'Dwyer's U.S. Air Force Reserve unit) went door-to-door in Bridgeport, Fairfield, Stratford, and Milford, Connecticut to track down Whitehead's long-ago neighbors and helpers. They also traced some who had moved to other parts of the state and the U.S. Of an estimated 30 persons interviewed for affidavits or on tape, 20 said they had seen flights, eight indicated they had heard of the flights, and two said that Whitehead did not fly.[27]


  Whitehead in his working clothes

Photographs have not been found showing any of Whitehead's airplanes in flight. According to William O'Dwyer, the Bridgeport Daily Standard newspaper reported that photos showing Gustave Whitehead in successful powered flight did exist and were exhibited in the window of Lyon and Grumman Hardware store on Main Street, Bridgeport, Connecticut in October 1903.[26]

Another missing photo, that purportedly showed a Whitehead aircraft in flight, was displayed in the 1906 First Annual Exhibit of the Aero Club of America at the 69th Regiment Armory in New York City. The photo was mentioned in a 27 January 1906 Scientific American magazine article.[36] The article said the walls of the exhibit room were covered with a large collection of photographs showing the machines of inventors such as Whitehead, Henry Berliner and Alberto Santos-Dumont. Other photographs showed airships and balloons in flight. The report said a single blurred photograph of a large birdlike machine propelled by compressed air constructed by Whitehead in 1901 was the only other photograph besides that of Samuel Pierpont Langley's scale model machines of a motor-driven aeroplane in successful flight.[33] In 1986, Peter L. Jakab, National Air and Space Museum (NASM) Associate Director and Curator of Early Flight, wrote that the image "may very well have been an in-flight photograph" of one of Whitehead's gliders.[36]

Two Connecticut Whitehead fans said they heard about yet another photograph; high school science teacher and pilot Andy Kosch and Connecticut State Senator George Gunther. They were told that a sea captain named Brown made a logbook entry about Whitehead flying over Long Island Sound and even photographed the airplane in flight.[36] A friend told Kosch he found the captain's leather-bound journal containing a photo of Whitehead in flight and a description of the event. After some difficulty, Kosch made contact with the owners of the journal, but they told him it was lost.[41]


To show that the No. 21 aircraft might have flown, Kosch formed the group "Hangar 21" and led construction of an American reproduction of the craft. On 29 December 1986 Kosch made 20 flights and reached a maximum distance of 100 m (330 ft). The reproduction, dubbed "21B," was also shown at the 1986 Experimental Aircraft Association Fly-In. Kosch received technical assistance to build the replica from Don Richardson, former professor in electrical engineering; Angelo "Mike" Cartabiano, retired R&D and flight safety engineer for Sikorsky; Arling "Pud" Schmidt, mass properties engineer for Boeing and McDonnell Douglas; Irving Burger, an engineer at Sikorsky's helicopter firm; Ken Terry, an R&D industrial engineer who studied nuclear submarines under Admiral Rickover; and Pratt & Whitney's Wes Gordeuk.[42]

In 1986, American actor and accomplished aviator Cliff Robertson, was contacted by the Hangar 21 group in Bridgeport and was asked to attempt to fly their reproduction No.21 while under tow behind a sports car, for the benefit of the press. Robertson said "We did a run and nothing happened. And we did a second run and nothing happened. Then the wind came up a little and we did another run and, sure enough, I got her up and flying. Then we went back and did a second one."[43] Robertson commented, "We will never take away the rightful role of the Wright brothers, but if this poor little German immigrant did indeed get an airplane to go up and fly one day, then let's give him the recognition he deserves."[44]

On 18 February 1998, another reproduction of No. 21 was flown 500 m (1,600 ft) in Germany.[45]


  The Herald article and drawing

In 1937, Stella Randolph stated in her first book that the late Richard Howell was the reporter who wrote the article about a Whitehead flight in the 18 August 1901 Bridgeport Herald[11] The article carried no byline.[46]

O'Dwyer wrote that Howell made the drawing of the No. 21 in flight, saying that Howell was "an artist before he became a reporter." [27] O'Dwyer spent hours in the Bridgeport Library studying virtually everything Howell wrote. O'Dwyer said: "Howell was always a very serious writer. He always used sketches rather than photographs with his features on inventions. He was highly regarded by his peers on other local newspapers. He used the florid style of the day, but was not one to exaggerate. Howell later became the Herald's editor."[47]

Kosch said, "If you look at the reputation of the editor of the Bridgeport Herald in those days, you find that he was a reputable man. He wouldn't make this stuff up."[48] Howell died before the controversy about Whitehead began.

The Bridgeport Herald article was published 18 August 1901, four days after the event it described. According to Aviation History, Whitehead detractors, including Orville Wright, used the delay in publication to cast doubt on the story, questioning why the newspaper would wait four days before reporting such important news. Orville Wright's critical comments were later quoted by the both the Smithsonian Institution and by British aviation historian Charles Harvard Gibbs-Smith. Aviation History explained that the Bridgeport Herald was a weekly newspaper published only on Sundays.[27] Writing in 1970, Gibbs-Smith doubted the veracity of the account, he said that the newspaper article "reads like a work of juvenile fiction..."[49]

  Mrs. Whitehead and skeptics

An early source of ammunition for both sides of the debate was a 1940 interview of Whitehead's wife Louise.[27] The Bridgeport Sunday Post reported that Mrs. Whitehead said her husband's first words upon returning home from Fairfield on 14 August 1901, were an excited, "Mama, we went up!" Mrs. Whitehead said her husband was always busy with motors and flying machines when he was not working in coal yards or factories. The interview quoted her as saying, "I hated to see him put so much time and money into that work." Mrs. Whitehead said her husband's aviation efforts took their toll on the family budget and she had to work to help meet expenses. She said she never saw any of her husband's reported flights.[27]

As to whether Whitehead's wife resented matters, Stella Randolph wrote "Mrs. Whitehead talked very freely and frankly with the writer, who made several visits to her home, in the 1930s, and there was never any intimation that she harbored any resentment about the past."[50]

Smithsonian Institution Curator of Aeronautics Peter L. Jakab said that Whitehead's wife and family did not know about his August 1901 flights.[36]

  Stanley Beach

Stanley Yale Beach was the son of the editor of Scientific American magazine and later became editor himself. He had a long personal association with Whitehead. His father, Frederick C. Beach, contributed thousands of dollars to support Whitehead's work with Stanley Beach's airplane design. Whitehead built an under-powered over-weight biplane that Stanley Beach designed, which never flew. When Whitehead told Stanley Beach that his design was faulty and could not work Stanley Beach got angry and sent some men who took the unfinished airplane away from Whitehead's workshop.

Beach claimed authorship of only one Scientific American article about Whitehead, that of 8 June 1901, a few weeks before the report in the Bridgeport Sunday Herald. The Scientific American article by Beach described Whitehead's machine as a "novel flying machine." Two photographs were included of a "batlike" craft.".[51][52] The article did not state Whitehead had flown and was published before Whitehead's reported flight of 14 August 1901. Unsigned articles in Scientific American in 1906 and 1908 did state that Whitehead had flown in 1901, but gave no details.

O'Dwyer asserted that all the articles in Scientific American which mentioned Whitehead had been written by Beach, but did not offer proof. O'Dwyer thus believed that, because of a statement Beach made many years later, Beach had "recanted" his earlier view that Whitehead had flown. O’Dwyer supported his opinion by asserting that Beach became a "politician" who was "rarely missing an opportunity to mingle with the Wright tide that had turned against Whitehead, notably after Whitehead's death in 1927."[27]

In 1939, Beach wrote down his thoughts about Whitehead, stating, "I do not believe that any of his machines ever left the ground under their own power in spite of the assertions of many persons who think they saw him fly."[36]

Beach stated that Whitehead "deserves a place in early aviation, due to his having gone ahead and built extremely light engines and aeroplanes. The five-cylinder kerosene one, with which he claims to have flown over Long Island Sound on 17 January 1902 was, I believe, the first aviation Diesel."[36]

  O'Dwyer, the Smithsonian and the Wrights

  The Smithsonian contract.

Reports of Whitehead's August 1901 flight in Connecticut were noticed by the Smithsonian Institution. Smithsonian Secretary Samuel Langley at that time was building his manned aircraft, the Large Aerodrome "A". In September 1901, Langley's chief engineer, Charles M. Manly, requested that F.W. Hodge, a staff clerk, look over Whitehead's Number 21 aircraft, then on public display in Atlantic City, New Jersey, where Hodge was staying.[53] Manly asked Hodge to estimate the dimensions of the wings, tail and propellers, the mechanism of the propeller drive and the nature of the construction, which Manly thought might be too weak. The item Manly stated he was "more interested in than anything else" was the acetylene engine. Manly stated he believed the claims made for the machine were "fraudulent." Hodge reported the machine did not appear to be airworthy.[54]

In 1903, two attempts to achieve manned powered flight with Langley's Aerodrome failed completely.[36] When the Wright brothers' flights became well known, the Smithsonian Institution tried to diminish their achievement and advance those of Langley. The Wrights offered their Flyer to the Smithsonian in 1910, but were rebuffed by the Institution. Instead, the Smithsonian gave aviator Glenn Curtiss permission to rebuild Langley's failed aircraft, an effort which included major but unpublicized design improvements. Curtiss and his team made several brief manned flights with the rebuilt Aerodrome in 1914. The Smithsonian took this as proof that Langley had created the first heavier than air machine "capable" of manned flight. Insulted by this development, Orville Wright lent the Flyer to the Science Museum in London, an act which eventually turned public opinion against the Smithsonian.[36] When the Flyer was finally brought back and presented to the Smithsonian in 1948, the museum and the executors of the Wright estate signed an agreement (popularly called a "contract") in which the Smithsonian promised not to say that any airplane before the Wrights' was capable of manned, powered, controlled flight.[36][note 5] This agreement was not made public.

In 1975, O'Dwyer learned about the agreement from Harold S. Miller, an executor of the Wright estate.[27] According to Aviation History, O'Dwyer pursued the matter and obtained release of the document, with help from Connecticut U.S. Senator Lowell Weicker and the U.S. Freedom of Information Act.[27] O'Dwyer said that during an earlier 1969 conversation with Paul E. Garber, a Smithsonian expert on early aircraft, Garber denied that a contract existed and said he "could never agree to such a thing."[27]

History by Contract, the book co-authored by O'Dwyer and Randolph, argued that the agreement unfairly suppressed recognition of Whitehead's achievements. However, the agreement contained no mention of Whitehead and was implemented only to settle the long-running feud between the Wrights and the Smithsonian regarding its false claims for the Aerodrome.

In July 2005, Peter Jakab of the Smithsonian's National Air and Space Museum and said the agreement with the Wright estate would not stop the Smithsonian from recognizing anyone as the inventor of the first airplane if indisputable evidence was found:

"We would present as accurate a presentation of the history of the invention of the airplane as possible, regardless of the consequences this might incur involving the agreement. Having said that, however, at this time, as in 1948, there is no compelling evidence that Whitehead or anyone else flew before the Wright brothers."[36]

Former Connecticut State Senator George Gunther said O'Dwyer's book History by Contract was too heavy-handed. Gunther said he had been having "cordial" conversations with the Smithsonian about giving credit to Whitehead, "but after O'Dwyer blasted them in his book, well, that totally turned them off."[48]

O'Dwyer learned the Smithsonian had published a Bibliography of Aeronautics in 1909 which included references to Whitehead. O'Dwyer said it was "hard to understand" why the Smithsonian never contacted Whitehead or his family to learn more about the flight claims.[33]

An article titled "Did Whitehead Fly?" in the January 1988 edition of Air Enthusiast magazine took an accusatory tone toward the Smithsonian: "The evidence amassed in his favour strongly indicates that, beyond reasonable doubt, the first fully controlled, powered flight that was more than a test 'hop', witnessed by a member of the press, took place on 14 August 1901 near Bridgeport, Connecticut. For this assertion to be conclusively disproved, the Smithsonian must do much more than pronounce him a hoax while wilfully turning a blind eye to all the affidavits, letters, tape recorded interviews and newspaper clippings which attest to Weisskopf's genius."[14] The writer was Georg K. Weissenborn, a professor of German language at the University of Toronto. He was in communication with O'Dwyer before and after the article's publication.[55]

  Possible influence on the Wright brothers

In the 1930s, Whitehead was said by three witnesses to have helped the Wright brothers by revealing his secrets perhaps two years prior to their first powered flights.[14]

Statements obtained by Stella Randolph in the 1930s from two of Whitehead's workers, Cecil Steeves and Anton Pruckner, claimed that the Wright brothers visited Whitehead's shop a year or two before their 1903 flights. The January 1988 Air Enthusiast magazine states: "Both Cecil Steeves and Junius Harworth remember the Wrights; Steeves described them and recalled their telling Weisskopf that they had received his letter indicating an exchange of correspondence."[14] Steeves said that the Wright brothers, "under the guise of offering to help finance his inventions, actually received inside information that aided them materially in completing their own plane."[56] Steeves related that Whitehead said to him, "Now since I have given them the secrets of my invention they will probably never do anything in the way of financing me."[56]

Orville Wright denied that he or his brother ever visited Whitehead at his shop and stated that the first time they were in Bridgeport was 1909 "and then only in passing through on the train."[57] This position is supported by Library of Congress historian Fred Howard, co-editor of the Wright brothers' papers,[31] and by aviation writers Martin Caidin and Harry B. Combs.[58]

O'Dwyer said Octave Chanute "encouraged" the Wrights to look into engines built by Whitehead. In a letter to Wilbur Wright on 3 July 1901, Chanute made a single reference to Whitehead, saying: "I have a letter from Carl E. Myers, the balloon maker, stating that a Mr. Whitehead has invented a light weight motor, and has engaged to build for Mr. Arnot of Elmira 'a motor of 10 I.H.P....'"[33][59]


Opinions about Whitehead's work and accomplishments differ sharply between two groups of researchers, with the mainstream viewpoint dismissive or very doubtful.[31][35][58][60][61][62] Establishment names include aviation historians William F. Trimble,[63] Fred Howard (a Wright brothers biographer), British historian Charles Harvard Gibbs-Smith, as well as Tom Crouch and Walter Boyne at the Smithsonian Institution. They all express serious doubt or flatly dismiss claims for Whitehead.

Researchers focused only on Whitehead include aspiring young author Stella Randolph inspired and informed by aviation buff Harvey Phillips in the 1930s, supported by prof John B. Crane's articles from 1936-1949. Researchers from 1963 and forward were: Major William O'Dwyer (ret.) of the U.S. Air Force Reserve in cooperation with Connecticut Aeronautical Historical Association ( CAHA); Harold Dolan, a Sikorsky Aircraft engineer and vice president/secretary of the CAHA; Harvey Lippincott, founder, and at the time president of CAHA; Stella Randolph; teacher and hang-glider Andy Kosch; and the Flugpionier-Gustav-Weisskopf-Museum in Whitehead's birthplace in Germany. These researchers have spent decades studying Whitehead and seriously consider the possibility that he made powered flights before 1903.[64][65]

In 1945, Whitehead's son Charles was interviewed on a national radio program as the son of the first man to fly. That claim was highlighted in a magazine article, which was condensed in a Reader's Digest article that reached a very large audience.[66] Orville Wright, then in his seventies, countered by writing an article, "The Mythical Whitehead Flight", which appeared in the August 1945 issue of U.S. Air Services, a publication with a far smaller, but very influential, readership. Wright listed several reasons for disbelieving Whitehead, then quoted John J. Dvorak, professor of Physics at Washington University in St. Louis, who had hired Whitehead to make Dvorak's engine design work in 1904 but rejected his flight claims in 1936. Dvorak said, "I personally do not believe that Whitehead ever succeeded in making any airplane flights. Here are my reasons: 1. Whitehead did not possess sufficient mechanical skill and equipment to build a successful motor. 2. Whitehead was given to gross exaggeration. He was eccentric – a visionary and a dreamer to such an extent that he actually believed what he merely imagined. He had delusions."[35] This was a reversal of Dvorak's original opinion about Whitehead's competence. When he worked with Whitehead, Dvorak reportedly believed that Whitehead "was more advanced with the development of aircraft than other persons who were engaged in the work."[29] The reversal of Dvorak's original opinion about Whitehead's competence followed a disagreement between the two men. Whitehead told Dvorak that his engine design was faulty and could not work. Dvorak became angry and subsequently made comments that discredited Whitehead.[citation needed]

In the 1950s British aviation historian and author Charles Harvard Gibbs-Smith studied The Papers of Wilbur and Orville Wright at the Library of Congress, and Randolph's 1937 book, and concluded that reports of Whitehead making a successful flight in advance of the Wright brothers were fabrications.[35] Gibbs-Smith wrote: "Unfortunately, some of those who advanced [Whitehead's] claims were more intent on discrediting the Wright brothers than on establishing facts."[35] He said in 1960 that no "reputable" aviation historian believes Whitehead ever flew.[35] In 1969 during his year as the senior scholar winner of the Charles A. Lindbergh Chair in Aerospace History, Gibbs-Smith extensively researched the field of early aviation developments and claims, and determined that all of Whitehead's claims of being first in powered flight were fabricated, that they were "flights of fancy".[49] He described the arc of Whitehead's career as a retrogression, that it moved from supposed early successes to less ambitious experiments, and then descended further to unlikely designs and public failure. Gibbs-Smith was convinced that any true success along the way would have brought Whitehead's achievements wide recognition, but this never happened.[49]

Gibbs-Smith also wrote that "Whitehead was incapable of solving the complex problems involved, especially that of a suitable engine."[67]

Interest in Whitehead's engines is indicated by the recollections of his daughter Rose, who said her father received numerous orders for them and even declined as many as 50 orders in a single day because he was too busy.[14]

An online biography based on the O'Dwyer and Randolph books asserts that the engine Whitehead purportedly used in Pittsburgh attracted the attention of Australian aeronautical pioneer, Lawrence Hargrave, who in 1889 invented a rotary engine: "This steam machine was so ingenious that several years later Lawrence Hargrave told of using miniature designs of "Weisskopf-style" steam machines, as well as the "Weisskopf System" for his model trials in Australia."[6]

Contemporary experienced amateur aviation researchers Nick Engler and Louis Chmiel[68][69][70] dismiss Whitehead's work and its influence, even if new evidence is discovered showing that he flew before the Wright brothers:

"While Whitehead believers insist that he was first to fly, no one claims that his work had any effect on early aviation or the development of aeronautic science. Even if someone someday produces a photo of No. 21 in flight on August 14, 1901, it will be nothing more than a footnote, a curious anomaly in the history of aviation."[71]

Whitehead expressed his own dedication to heavier-than-air flight in a letter to American Inventor magazine in 1902. He wrote that because "the future of the air machine lies in an apparatus made without the gas bag, I have taken up the aeroplane and will stick to it until I have succeeded completely or expire in the attempt of so doing."[15] Newspapers around the world had reported about Santos-Dumont's experiments with motorized and steerable gas bags for a few years when Whitehead wrote this.


  • The "Aviation Pioneer Gustav Weißkopf Museum" was established in Leutershausen, Germany in 1974.
  • The German post office has issued two stamps commemorating Whitehead's flights in No. 21
  • A memorial fountain and sculpture commemorating Whitehead's aviation achievements was dedicated in Bridgeport in May 2012.[72]

The English word games are:
○   Anagrams
○   Wildcard, crossword
○   Lettris
○   Boggle.


Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.


Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
