Harry S Morrow was born in 1909 and grew up in Pennsylvania. He moved to California and studied aeronautical engineering, though his passion was always for cars. He raced on dirt tracks prior to the war and was part owner of the influential Road & Track magazine. In 1951, he founded Autobooks in Burbank, California. Harry was highly influential in the development of Formula 3 in the US and built the second car (The first being Charles Nerpel's Andree) which he christened "Scarecrow". After a number or retirements, he resorted to the more conventional route and acquired a Cooper Mk V. His stable also included Peter Collins' JBS, the Trimax, Bruce Kesslers' Cooper Mk IX and a Kieft. Harry founded the 500cc Club of America in 1950, though sadly he died before the Club was resurrected by Tom Cecil.
