Harry David Kerr (8 October 1880 Santa Rosa, California – 21 May 1957 Los Angeles) was an American songwriter, lyricist, author, and lawyer. Kerr became active in music at age 15 (1895). The practice of law had been his prime avocation until 1920, when he decided to focus on songwriting. But he still continued to use his legal training in music. In 1922, while living in New York City, Kerr prepared the incorporation documents for the American Society of Composers, Authors and Publishers (ASCAP), of which he had become one of 90 charter members at its founding in 1914.
