Juan Manuel Fangio (June 24, 1911 – July 17, 1995), nicknamed El Chueco ("knock-kneed") or El Maestro ("The Master"), was a racing car driver from Argentina, who dominated the first decade of Formula One racing. He won five Formula One World Driver's Championships — a record which stood for 46 years until eventually beaten by Michael Schumacher — with four different teams (Alfa Romeo, Ferrari, Mercedes-Benz and Maserati), a feat that has not been repeated since. Many still consider him to be the greatest driver of all time. He has the highest winning percentage in Formula One (46.15%) compared to Michael Schumacher's 33.83%..
