The father of the 300 SL was chief engineer Rudolf Uhlenhaut, who had been with Mercedes since the 1930s. He played a major role in the development of Mercedes-Benz vehicles after the Second World War. Uhlenhaut was a multi-talent, which was manifested, among other things, in the fact that he was as fast on the racetrack as Formula 1 drivers. The tubular spaceframe was his idea.
