Ayrton Senna da Silva was a Brazilian racing driver who competed in Formula One from 1984 to 1994. Senna won three Formula One World Drivers' Championship titles with McLaren, and—at the time of his death—held the record for most pole positions (65), among others; he won 41 Grands Prix across 11 seasons.
Born and raised in São Paulo, Senna began competitive kart racing aged 13; his first go-kart was built by his father using a lawnmower engine. After twice finishing runner-up at the Karting World Championship, Senna progressed to Formula Ford in 1981, dominating the British and European championships in his debut seasons. He then won the 1983 British Formula Three Championship amidst a close title battle with Martin Brundle, further winning the Macau Grand Prix that year. Senna signed for Toleman in 1984, making his Formula One debut at the Brazilian Grand Prix. After scoring several podium finishes in his rookie season, Senna moved to Lotus in 1985 to replace Nigel Mansell, taking his maiden pole position and victory at the rain-affected Portuguese Grand Prix, a feat he repeated in Belgium.
