French pioneer of the front-wheel-drive car who contributed to the development of such vehicles in two ways. The first way was in developing and promoting the Tracta joint (designed by his friend Pierre Fenaille), which was, until manufacturing techniques had progressed sufficiently to allow the successful manufacture of the constant velocity joints commonly in use today, the preferred choice of most manufactures of vehicles that had driven front wheels.
The second way he contributed to the development of front-wheel-drive vehicles was in designing and in some cases manufacturing front-wheel-drive cars. The Tracta Gephi was his first design and it was this car that inspired him to design a constant velocity joint. All subsequent Tracta cars, and there were about two hundred manufactured between 1927 and 1932, used it.
He died on 19 August 1992, aged 93, in Neuilly-sur-Seine.
