About Jo Siffert
Joseph "Jo" Siffert (French pronunciation: [ʒo(zɛf) sifɛʁ]; 7 July 1936 – 24 October 1971) was a Swiss racing driver, who competed in Formula One from 1962 to 1971. Siffert won two Formula One Grands Prix across 10 seasons. Affectionately known as "Seppi" to his family and friends, Siffert was born in Fribourg, 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 1964 and 1965 Mediterranean Grands Prix non-Championship Formula One races, both times beating Jim Clark by a very narrow margin. He won two World Championship races, one for the Rob Walker Racing Team and one for BRM. Siffert died at the 1971 World Championship Victory Race, a non-Championship Formula One 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, wedded with his second wife Simone from the height of his career in the late 1960s to the time of his death. They had two children together, Véronique and Philippe. 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 few earlier victories on twisty tracks. Siffert was killed in the non-championship World Championship Victory Race at Brands Hatch, Kent, England, the scene of his first victory in 1968.
