Acted, during World War Two, as President Truman's chauffeur on one incredibly historic occasion; Len was the driver for the President at Potsdam, Germany, in July 1945, where Truman was to meet Churchill, Atlee and Stalin. However Duncan served the US Army with great courage prior to that, working his way up to being a sergeant. Len started racing in 1928, before moving into midget racing in the early 1930's and then sprint car racing soon after, winning many events, but was at his very best in dirt-track midget racing. Duncan raced for decades, very successfully, taking over 500 wins and the AAA Eastern Midget Championship for three successive years from 1953 to 1955. He also won the ARDC Midget Championship eight times from 1955 right up to 1967. Len carried on racing until 1982, when in his 70's, in the American Three-Quarter Midget Racing Assocation run series, who when Len died, formed a memorial race in his honour. Len, considering he raced for over 50 years had remarkably few accidents, was incredibly consistent, but was also a huge influence and support to younger drivers which included the likes of Mario Andretti.
