Alain Prost, four-time Formula 1 World Champion nicknamed "the Professor," joined Ferrari in 1990—the first driver signed by the Scuderia following the death of Enzo Ferrari in 1988. Driving the Ferrari 641, he won five races in his first season, including in Mexico from 13th on the grid. He lost the title in the penultimate race in Japan when Senna deliberately took him out of the race at the first corner. His teammate was Nigel Mansell; his time at Ferrari ended in 1991.
