Ayrton Senna da Silva (Brazilian Portuguese: [aˈiʁtõ ˈsẽnɐ dɐ ˈsiwvɐ] (listen); 21 March 1960 – 1 May 1994) was a Brazilian racing driver who won the Formula One World Drivers' Championship in 1988, 1990 and 1991. Senna is one of three Formula One drivers from Brazil to win the World Championship and won 41 Grands Prix and 65 pole positions, with the latter being the record until 2006. He died in an accident leading the 1994 San Marino Grand Prix driving for the Williams team.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.
Senna was recognised for his qualifying speed over one lap, and from 1989 until 2006 he held the record for most pole positions. He was also acclaimed for his wet weather performances, such as the 1984 Monaco Grand Prix, the 1985 Portuguese Grand Prix, and the 1993 European Grand Prix. He holds a record six victories at the Monaco Grand Prix, is the fifth-most successful driver of all time in terms of race wins and has won more races for McLaren than any other driver. Senna courted controversy throughout his career, particularly during his turbulent rivalry with Prost. In the Japanese Grands Prix of 1989 and 1990, each of which decided the championship of that year, collisions between Senna and Prost determined the eventual winner.
