Joseph Siffert (; 7 July 1936 – 24 October 1971) was a Swiss racing driver. Affectionately known as "Seppi" to his family and friends, Siffert was born in Fribourg, Switzerland, the son of a dairy owner. He initially made his name in racing on two wheels, winning the Swiss 350 cc motorcycle championship in 1959, before switching to four wheels with a Formula Junior Stanguellini. Siffert graduated to Formula One as a privateer in 1962, with a four-cylinder Lotus-Climax. He later moved to Swiss team Scuderia Filipinetti, and in 1964 joined Rob Walker's private British Rob Walker Racing Team. Early successes included victories in the non-Championship 1964 and 1965 Mediterranean Grands Prix, both times beating Jim Clark by a very narrow margin. He won two races in Formula One for the Rob Walker Racing Team and BRM. He died at the 1971 World Championship Victory Race, having his car roll over after a crash caused by a mechanical failure and being caught under the burning vehicle. Siffert was married twice and to his second wife Simone during the height of his career in the late 1960s and at the time of his death. They had two children together, Véronique and Philippe.

Aged 12, Siffert and his father went to Bern to see the 1948 Swiss Grand Prix at the Bremgarten circuit, and it was at this event where Siffert wanted to be a racing driver. Formula One In 1968, Siffert drove into the F1 history books by winning the 1968 British Grand Prix at Brands Hatch in Rob Walker Racing Team's Lotus 49B, beating Chris Amon's Ferrari into second place after a race-long battle. This is regarded as the last GP victory by a genuine privateer. In 1971 as a BRM team driver he scored his second Formula One Championship race victory at the Austrian Grand Prix held at the Österreichring. Sports cars While Siffert's status in F1 grew slowly, his fame came as a leading driver for the factory Porsche effort in its quest for the World Sportscar Championship. In 1968, Siffert and Hans Herrmann won the 24 Hours of Daytona and the 12 Hours of Sebring in a Porsche 907, marking the first major outright wins for the company, apart from a
