Ayrton Senna grew from being a clumsy toddler who couldn't climb stairs into one of the greatest Formula One drivers of all time.
After early successes in his motorsport career, Senna was catapulted into the world's premier motorsport championship with the unfancied Toleman team - and straight away he was comfortable sharing a track with legends like Niki Lauda. Over the next eleven years, Senna won three Drivers' Championships and legions of fans thanks to his no-holds-barred driving style.
Senna drove for three legendary F1 teams - Lotus, McLaren and Williams - but his aggression behind the wheel led to bad-tempered clashes with rivals. His battles and fallouts with teammate Alain Prost dominated the late 1980s and early 1990s, and he regularly locked horns with team bosses and F1 administrators. It all came to a sudden end when Senna crashed while leading the 1994 San Marino Grand Prix, and the motorsport world was plunged into mourning over the early death of a driver who'd become an icon.
