Giotto Bizzarrini was an Italian engineer. In 1957, he was recruited by Ferrari, initially as a test driver, and quickly rose to head the development of sports and GT cars. His ideas were incorporated into the 250 GT SWB, the 250 TR Testa Rossa, and the three-liter Testa Rossa V12, among others. His masterpiece was the 1962 250 GTO, which he began working on in 1960: Ferrari wanted an aerodynamically superior GT racing car compared to the 250 GT SWB, also because Jaguar had just introduced the E-Type. In 1961, he left Ferrari as part of the "Great Walkout."
