Seymour was born on October 23, 1892 in New York City. He began his show business career as a professional dancer in vaudeville at the age of 15. In the 1920s he became a dance director in New York, creating and staging dance numbers for such shows as Hit the Deck (1927), Whoopee! (1928), and Rosalie (1928).
In 1929, he moved to Hollywood to begin staging musical films.
