Ayrton Senna da Silva; (21 March 1960 – 1 May 1994) was a Brazilian racing driver who won three Formula One drivers' championships. He was killed in a tragic accident while leading the 1994 San Marino Grand Prix. Till this day, the leading causes of his death remain disputed. He remains the last driver fatality in Formula One, as of 2013. He is also often considered to be "one of the greatest drivers to ever race in Formula 1."
Senna began his motorsport career in karting, moving up to open-wheel racing in 1981, and winning the British Formula 3 championship in 1983. 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 Marlboro McLaren-Honda. Between them, they won all but one of the 16 grand prix that year and Senna claimed his first drivers' World Championship. Prost claimed the championship in 1989, and Senna his second and third championships in 1990 and 1991. In 1992, the Williams-Renauly 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. This would be his last year in Formula 1, ending at his tragic death Imola.
