Émile Constant Levassor
Émile Constant Levassor (21 January 1843 – 14 April 1897) was a French engineer and a pioneer of the automobile industry and car racing in France.
While working at Panhard Levassor introduced a series of innovations that effectively created the modern car. Levassor moved the engine from the rear to the front of the car and cooled it via a front-mounted water radiator rather than relying, as had been customary, on natural aspiration, which was often insufficient. He also introduced a crankshaft to link the engine with the gearing, eschewing the bicycle-style belt drive of previous cars; and he installed a clutch pedal and a gear stick, situated between the seats, to operate the gearbox, thus creating the first modern transmission. The siting of the engine on the front of the car rather than the rear provided far more room for passengers.
