Ana Delfosse was an Argentinian race-car driver and Formula One mechanic who worked for Grand Prix champion Juan Fangio and later became the first woman to win a pure-speed auto race in Argentina. Born in 1931 near Punta Arenas, Chile, she grew up on a sheep farm in Argentina. Enamored of speed at an early age, she rode a horse called Blitz (German for "lightning"). Watching Fangio driving by the ranch in his racing car led to her involvement with racing cars. At the age of 16, she became part of Fangio's pit crew and later became a driver, racing in the Andes and elsewhere. On June 5, 1960, she won a race in Buenos Aires, driving a Porsche Gordini.
