Reginald Hazeltine Bassett (September 3, 1878 – April 24, 1951) was an American composer and orchestrator who led a prolific career in film. He contributed music to over one hundred major movies from the 1920s to the 1940s. He is virtually unknown because he worked under a film studio system that not only controlled the copyrights to his music but also allowed others to take screen credit for his work.

Bassett worked collaboratively on film score compositions with other Hollywood composers from Ira Gershwin to Hugo Friedhofer:

In any event, Friedhofer talks at length about Bassett in his oral history, mentioning the scores on which he worked with him (including Intermezzo and Gone With the Wind) and Bassett's association with Forbstein's predecessor at Warner Bros., Lou Silvers.^[1]
