I.P. stood for Isaac Phillips. Worked as a car dealer in Pittsburgh, but died suddenly of natural causes. Fetterman was an expert at the local Uniontown board track, where he took notable wins in 1919 and 1921, ahead of the likes of Roscoe Sarles. Fetterman also served in the US Army during World War 1. Isaac retired from racing in 1922 and then tried to establish a board track at Bridgeville, Pennsylvania, but without success before his passing at the age of thirty-seven. Also known as Red, Fetterman's two brothers were involved with cars or racing but they too were dead before the start of 1926; brother Nat was killed in a dirt-track race in Monongahela, Pennsylvania, whilst Clarence, who worked as a mechanic, died of carbon monoxide poisoning in 1924.
