Monday 4th October 1858
Born on this day, Leon Serpollet, in Culoz, France. In 1896, Serpollet invented and perfected the flash boiler, which made steam a much more practical source of power for an automobile. The oil-fired flash boiler fed steam to a very advanced four-cylinder enclosed engine similar to the contemporary petrol engine design including poppet valves and an enclosed crankcase. Serpollet produced his own automobiles under the name Serpollet and Gardner-Serpollet until his death in 1907.
