LeRoy Prinz started his career after running away from a boarding school. He came to France prior to WWI, where he earned his money dancing in nightclubs. After the outbreak of the war he became a pilot. He was shot down 15 times. After the war he fought as a mercenary in a civil war in Nicaragua, until US forces landed and intervened. Deciding he had pressed his luck as far as it would go, and having had his fill of fighting, he found work as a dance director on Broadway. He worked mostly for Paramount (1933-41) and Warner Bros. (1942-57). Among his best remembered works are The Big Broadcast of 1938 (1938) and the bizarre All-American Co-Ed (1941).
