Hal Mooney, born Harold Mooney, (February 4, 1911 - March 23, 1995) was an American composer and arranger. 　　Hal Mooney was born in Brooklyn, New York. As a young man, Mooney was a professional pianist. He attended Brooklyn and St. John's Law Schools. After studying music under New York University professor Orville Mayhood and then under the influential Joseph Schillinger, he was invited to join the arrangers' roster for the popular Hal Kemp Orchestra, alongside John Scott Trotter (who was about to leave the band) and Lou Busch. Mooney then moved to the Jimmy Dorsey Orchestra, but World War II was breaking out and soon he was called up by the United States Army.
