Wurm grew up in Salem, New York and attended Salem Central School. In September 1941, he signed a contract with the Brooklyn Dodgers and began pitching in their farm system.[1] At age 18 in 1942, he pitched for the Olean Oilers and tied the PONY League record for strikeouts in a game.[2] The following February, he was inducted into the United States Army and was shipped out to Sicily by the summer.[1] According to the Brooklyn Daily Eagle, Wurm, then 19 years old, "was one of the first Americans to enter Cassino" but was medically discharged shortly thereafter due to "battle fatigue." He described a friend and fellow soldier dying in his arms after they were both hit by a German artillery shell.[3]
He appeared in one game in Major League Baseball for the Brooklyn Dodgers during the 1944 season. He started the game,[4] giving up four runs while only getting one out, a strikeout.[5]
