The story
Founded by Henri Farman, Maurice Farman and Richard Farman in 1908, in Boulogne-Billancourt.1
In 1907, Henri Farman bought his first aircraft from Gabriel Voisin and soon began to improve the design of the aircraft; as a result it was known as either Farman I or Voisin-Farman I. In 1908, after further modifications which included re-covering it with Continental rubberized fabric and the addition of side-curtains, the aircraft was re-designated Farman I-bis. Ailerons were fitted after Wilbur Wright's flying demonstration at Le Mans in August 1908.
A second aircraft, to be called Farman II, was built by the Voisin brothers incorporating design refinements to Farman's specification. Voisin sold this aircraft to J.T.C. Moore-Brabazon, who exported it to England, where it was renamed the Bird of Passage. This episode angered Farman, who in early 1909 ended his association with Voisin and started building his own aircraft.
Aircraft designed and built by Henri Farman had a HF prefix, while examples designed and built by his brother Maurice carried a MF prefix.
