He then took eight, eleven and thirteen passengers aloft the following month. He is also known as the world's first professional test pilot.The son of a blacksmith, in 1902 he became a graduate Gadz'Art, an engineer of 'Arts and Crafts' of the École Nationale Supérieure d'Arts et Métiers (ENSAM) – a prestigious university (grande ecole) specialising in engineering. His aeronautic career included working with Gabriel Voisin, the Seguin brothers, Henri Farman, Ernest Archdeacon and Louis Blériot.

He achieved 128.418 km/h (79.795 mph) over the 33 kilometres (21 mi) flight between Etampes and Toury in a Blériot using his own enhancements to the Gnome Omega 50 hp (37 kW) motor.He died in a crash on 18 June 1911 during the Paris–London–Paris leg of Le Circuit Européen (Tour of Europe) air race.
