Etienne Dormoy
Etienne Dormoy, 1924.

February 10, 1885--Etienne Dormoy born in Vandoncourt (Doubs), France to Pastor Paul Amos Dormoy and his wife Antoinette Berthe Pierret.
July 26, 1906--Dormoy graduated from Industrial Institute of Northern France in Lille. He earned a diploma from the Division of Civil Engineering Department (Electrical Department). Dormoy join the French Military in 1906 as an engineer. He completed his service in 1908.
Dormoy became a draftsmen for the Deperdussin Company of France. The company built the world's first monocoque fuselages. Dormoy learned the art of wrapping and gluing narrow thin strips of wood around a form to make the strong airplane body without any struts so well he became an expert at it. In an interview in February, 1958, he claimed that he was the designer of the first monocoque fuselage.
Dormoy met Harold D. Kantner, who went to Paris for the Aero Club of America to purchase an 18-cylinder, 160 h.p. Gnome Engine. The Deperdussin Company was to build the airframe. Kantner introduced Dormoy to Maximillian Schmiddt who hired Dormoy to move to Paterson, New Jersey to build the first true monocoque built in the United States.
Kantner won the New York Times 4th of July Race in the Schmiddt monoplane with the monocoque built by Dormoy. Dormoy returned to France, joined the French Air Force and became a pilot in 1915. He was one of the first pilots to make night flights in search of zeppelins. Dormoy returned twice with his Voisin biplane riddled with bullet holes. One time five holes, another three.
Dormoy flew his last mission in January. He was not released from the French Air Force at that time, but was sent back to the Deperdussin Company to help design the "Spad" fighter.
With an agreement between the United States Army Signal Corps and the Deperdussin Company, Dormoy was brought back to the U.S. with two Spads and blueprints to teach the Americans how to build the Spad at the new Curtiss Elmwood Plant in Buffalo, New York. Several fuselages were made, but the complete plane was never made at the factory. This was due to the lack of the Hispano engines. The war ended leaving no use for the airplane, so the project was abandoned.
Dormoy joined the Packard Motor Company.
Dormoy was fired from the Packard Motor Company for drawing airplane designs instead of automobiles. He then became a civil engineer for the U.S. Army Air Force.
     He designed a device to spray war chemicals from an airplane. This became the forerunner for crop dusting.

Dormoy built his "Famous Flying Bathtub" airplane out of materials bought from a hardware store. The Henderson Motorcycle engine was the only thing that didn't come from the hardware store. He entered his plane in the 1924 Dayton Daily News Light Airplane Race and won. He also won the Rickenbacker Trophy and the Rickenbacker Traveling Trophy which was to go to each year's winner of the race. There was just the one race and the trophy was later given to Dormoy. (This trophy was stolen from Dormoy's San Diego home in the mid-1950's. It was 32 inches tall.)

Dormoy ended his career with the U.S. Army Air Force. He went to work for Buhl Aircraft Company. He designed all of the Buhl planes, including the Buhl Airster, a mail plane, Buhl Airsedan and the Bull Pup (test piloted by James M. Johnson).
The Buhl Aircraft Company closed due to the depression. Dormoy then joined the Boeing Aircraft Company of Seattle. He was assigned to the wind tunnel division and helped design the P-26 Peashooter.
Etienne Dormoy became an American citizen in Seattle, Washington on October 14, 1933.
Dormoy left Boeing due to allergies induced by the damp Seattle climate. He joined the Consolidated Aircraft Company of San Diego (later renamed Convair).
     Consolidated sent Dormoy to Russia to oversee an American crew who was helping the Russians build a Catalina PBY. Many problems developed, including damaged parts in shipment, lack of communication and lack of cooperation by the Russians.
Dormoy returned to the United States and worked for Convair until he retired. He helped Isaac Laddon design the Catalina PBY.
Dormoy retired from Convair as senior design engineer. After retirement he remained active by designing a collapsible boat and a barbecue grill.
On February 28, 1959, Etienne Dormoy died in a San Diego hospital of a heart ailment.
