Bengt Ronnie Peterson (Swedish pronunciation: [ˈrɔni ˈpɛtɛˈʂon]; 14 February 1944 – 11 September 1978) was a Swedish racing driver. Known by the nickname ‘SuperSwede’, he was a two-time runner-up in the FIA Formula One World Drivers’ Championship. Ronnie Peterson began his motor racing career in kart racing, traditionally the discipline where the majority of race drivers begin their careers in open-wheel racing. After winning a number of karting titles, including two Swedish titles in 1963 and 1964, he moved on to Formula Three, where he won the Monaco Grand Prix Formula Three support race for the 1969 Grand Prix. Later that year he won the European Formula Three Championship and moved up into Formula One, racing for the March factory team. In his three-year spell with the team, he took six podiums, most of which were scored during the 1971 Formula One season in which he also finished as runner-up in the Drivers’ Championship.

After seeing out his three-year contract at March, Ronnie Peterson joined Colin Chapman’s Team Lotus in the 1973 season, partnering defending champion Emerson Fittipaldi. During his first two seasons with Lotus, Peterson took seven victories, scoring a career-best 52 points in 1973. After a poor 1975 season, Peterson moved back to March and scored his final victory for the team at the 1976 Italian Grand Prix. After spending the 1977 season with Tyrrell, he moved back to Lotus for the 1978 season as “number two” driver to Mario Andretti. Peterson scored two wins, at the South African and Austrian Grand Prix races, and would finish second in the Drivers’ Championship standings despite his fatal first-lap accident at Monza during the Italian Grand Prix. Ronnie died at age 34 due to injuries suffered after his Lotus went into the barriers and crashed.
