Marcel Leyat (March 26, 1885 (Die, Drôme) - December 3, 1986) was an engineer, inventor, aviation pioneer, and aeronautical and automobile manufacturer. He graduated from the École Centrale Paris in 1907. From 1908, he worked for the Société Astra and built a biplane glider called the Quand Quelle (When, which). In 1909 he targeted "the first powered crossing of the English Channel", but Louis Blériot succeeded on July 21, three weeks before his De Dion-Bouton 5 hp powered plane completed a flight of 200 m at 10 m elevation on August 15. In 1910, he built a propeller-driven biplane 11 m long and 16 m wide. He obtained the FAI pilot's license in 1911. During the First World War, he built several aircraft, including a "living wing" bomber. In all, he designed and built around thirty different aircraft up to World War II.

In 1927, a Hélica reached the speed of 106 mph at the Autodrome de Linas-Montlhéry circuit. Leyat continued to experiment with his Helica. He tried using propellers with two and four blades.

Between 1919 and 1925, Leyat sold 30 vehicles.
