Oliver George Wallace (August 6, 1887 – September 15, 1963) was an English-born American composer and conductor. He was especially known for his film music compositions, which were written for many animation, documentary, and feature films from Walt Disney Studios. He initially worked primarily on the West Coast in Seattle as a conductor of theater orchestras and as an organist accompanying silent films. At the same time, he also made a name as a songwriter, writing tunes such as the popular "Hindustan". With the advent of the talking film era, he worked increasingly for Hollywood film studios in the 1930s.
