Mark Donohue (March 18, 1937 – August 19, 1975) was a distinguished American racing driver and engineer, celebrated for his versatility and technical acumen across various motorsport disciplines. Born in Haddon Township, New Jersey, Donohue earned a mechanical engineering degree from Brown University, which he adeptly applied to his racing endeavors.

In 1966, Donohue began a pivotal partnership with team owner Roger Penske, leading to significant successes in the United States Road Racing Championship (USRRC) and the Trans-Am Series. His engineering insights and driving prowess were instrumental in securing multiple championships for Penske Racing.

Donohue's achievements extended to the Indianapolis 500, where he won in 1972, setting a record speed that stood for over a decade. He also made notable contributions to Formula 1, driving for Penske's team and earning a podium finish at the 1971 Canadian Grand Prix.

Tragically, Donohue's life was cut short following a crash during a practice session for the 1975 Austrian Grand Prix. His legacy endures through his innovative approach to racing and his profound impact on motorsport engineering.
