Two identical pusher biplane machines, with Antoinette engines, had been built by the Voisin brothers for two early aviation pioneers, one for Léon Delagrange in March 1907, and the second for his friend and rival the Anglo-French pioneer Henry Farman (1874-1958) in October 1907.
Gabriel and Charles Voisin were among Europe’s leading pioneer aviators. Their classic 1907 pusher biplane was one of the most significant aircraft of the pre-World War I era. In 1912, they developed a military version. Thereafter they built aircraft almost exclusively for military contracts.
The Voisin 1912 Type, as it was referred to by the French military, also called the Type 1, launched the standard configuration of almost all Voisin aircraft throughout the war. The Voisin design philosophy was conservative. There were only slight, incremental design changes in the airframes during the war. Improvements principally consisted of installing more powerful engines, usually necessitating wings of greater span.
