Didier Joseph Louis Pironi (26 March 1952 – 23 August 1987) was a French racing driver. During his career he competed in 72 Formula One World Championship Grands Prix, driving for Tyrrell (1978–1979), Ligier (1980) and Ferrari (1981–1982). He won the 24 Hours of Le Mans in 1978 driving a Renault Alpine A442B.

Professional driving career (1972–1982)

Pironi was born in Villecresnes, Val-de-Marne. He is the half brother of José Dolhem (they had the same father and their mothers were sisters). He began studying as an engineer and earned a degree in science, but entering the family construction business fell by the wayside following his enrollment at the Paul Ricard driving school. He was awarded Pilot Elf sponsorship in 1972, a program designed to promote young French motorsport talent, that also led Alain Prost, René Arnoux and Patrick Tambay into Formula One. After becoming Formula Renault champion in France in 1974, taking the Super Renault championship title in 1976 and winning the prestigious Monaco Grand Prix Formula Three support race in 1977, Pironi made his F1 debut at the Argentine GP on 15 January 1978. This was with Ken Tyrrell's team which, despite being British, had a strong working relationship with Elf, dating back to the late 1960s. In the same year, Pironi was part of the massive Renault squad tasked with winning the 24 Hours of Le Mans. Partnering Jean-Pierre Jaussaud in the team's second car, the unusual "bubble roof" A442B, he won the race by four laps from the rival Porsche 936s.
