Karl Jochen Rindt ([kaʁl ˈjɔχn̩ ʀɪnt]; 18 April 1942 – 5 September 1970) was a German-born racing driver who represented Austria during his career. In 1970, he became the only driver to posthumously win the Formula One World Drivers' Championship, after being killed in practice for the Italian Grand Prix.
Rindt started motor racing in 1961, switching to single-seaters in 1963, earning success in both Formula Junior and Formula Two. In 1964, Rindt made his debut in Formula One at the Austrian Grand Prix, before securing a full drive with Cooper for 1965. After mixed success with the team, he moved to Brabham for 1968 and then Lotus in 1969. It was at Lotus where Rindt found a competitive car, although he was often concerned about the security of the notoriously unreliable Lotus vehicles. He won his first Formula One race at the 1969 United States Grand Prix.
