Richard Rodgers
Their first professional production was the 1920 Poor Little Ritz Girl. In 1925 they became well known for the song "Manhattan".  The duo then wrote several hit shows for both Broadway and London. Because of the Depression in the 1930s, they went to work in Hollywood. In 1935, they returned to Broadway. They wrote an almost unbroken string of hit shows.  This ended with Hart's death in 1943.
