Ayrton Senna da Silva (21 March 1960 – 1 May 1994) was a Brazilian racing driver who won the Formula One World Drivers’ Championship in 1988, 1990 and 1991, and who is widely regarded as one of the greatest Formula One drivers of all time. He died in an accident while leading the 1994 San Marino Grand Prix.
Senna began his motorsport career in karting, moved up to open-wheel racing in 1981, and won the 1983 British Formula Three Championship. He made his Formula One debut with Toleman-Hart in 1984, before moving to Lotus-Renault the following year and winning six Grands Prix over the next three seasons. In 1988, he joined Frenchman Alain Prost at McLaren-Honda. Between them, they won all but one of the 16 Grands Prix that year, and Senna claimed his first World Championship. Prost claimed the championship in 1989, and Senna his second and third championships in 1990 and 1991. In 1992, the Williams-Renault combination began to dominate Formula One. Senna nonetheless managed to finish the 1993 season as runner-up, winning five races and negotiating a move to Williams in 1994.
