John Herndon Mercer was an American lyricist, songwriter, and singer, as well as a record label executive who co-founded Capitol Records with music industry businessmen Buddy DeSylva and Glenn E. Wallichs. He is best known as a Tin Pan Alley lyricist, but he sometimes composed music, despite not knowing piano or standard musical notation, and was a popular singer who recorded his own as well as others' songs from the mid-1930s through the mid-1970s. Mercer wrote the lyrics to more than 1,200 songs, including compositions for movies, Broadway shows, and well-known standards of the time, including "Autumn Leaves", "Days of Wine and Roses", "Hooray for Hollywood", "I'm an Old Cowhand", and "Moon River". He received eighteen Oscar nominations and won four Best Original Song Oscars.
