From Wikipedia:

As Artist Direct documents: Schwartz placed his first songs in a Broadway show, The New Yorkers (March 10, 1927). By 1928, he had closed his law office and convinced Dietz to write with him. Their first songs together were used in the Broadway revue The Little Show (April 30, 1929) and included "I Guess I'll Have to Change My Plan", which belatedly became a hit three years later when it was recorded by Rudy Vallée. Schwartz's career was launched, and in 1930 he contributed songs to six shows, three in London and three in New York, the most successful of which was Three's a Crowd (October 15, 1930), which featured the same cast as The Little Show and featured the hit "Something to Remember You By". Schwartz also started contributing songs to motion pictures, beginning with "I'm Afraid of You" (lyrics by Ralph Rainger and Edward Eliscu) in Queen High (1930).

Among other Broadway musicals for which Schwartz wrote the music are: The Band Wagon (1931), A Tree Grows in Brooklyn (1951), By the Beautiful Sea (1954), The Gay Life (1961), and Jennie (1963). His films include the MGM musical The Band Wagon (1953) with lyricist Howard Dietz.

Schwartz also worked as a producer, for Columbia Pictures. His work includes the musical Cover Girl (1944) and the Cole Porter biographical film Night and Day (1946).
