Early life

Born in Haddon Township, New Jersey, Donohue grew up in Summit, graduated from the Pingry School in Hillside, and entered Brown University in Providence, Rhode Island. At the age of twenty-two, while a senior at Brown, Donohue began racing his 1957 Corvette. He won the first event he entered, a hillclimb in Belknap County, New Hampshire. He graduated from Brown in 1959 with a bachelor's degree in mechanical engineering.Donohue won the SCCA national championship in an Elva Courier in 1961. An experienced race driver named Walt Hansgen (who worked for Inskip Motors in NY & RI) recognized Donohue's ability and befriended him, eventually providing an MGB (through Inskip Motors in Providence, RI and prepped by their race shop Competition Engineering) for Donohue to race at the 1964 Bridgehampton 500-mile (800 km) SCCA endurance event, which he won. Hansgen arranged for Donohue to become his teammate in 1965, co-driving a Ferrari 275 at the 12 Hours of Sebring endurance race, which they finished in 11th place. That year, Donohue also won two divisional championships: in SCCA B Class in a GT350 and in SCCA Formula C in a Lotus 20B.Donohue was hired on March 29, 1964 by Jack Griffith [Griffith Motors, Syosset, N.Y./Plainview, N.Y.] as design engineer for the Griffith, formerly TVR Grantura Mk III, powered by a Ford 289 cid (4.7l) V8 engine. He went on to assist TVR's David Hives in designing the Series 400 Griffith and then working on the ill-fated Bob Cumberford-designed, Intermeccanica-(Torino, Italy) produced Series 600 Griffith.
