Donald David Dixon Ronald O’Connor (August 28, 1925 - September 27, 2003) was an American dancer, singer, and actor who came to fame in a series of movies in which he co-starred alternately with Gloria Jean, Peggy Ryan, and Francis the Talking Mule. Perhaps his most famous performance was as Gene Kelly's sidekick in the musical Singin’ in the Rain (1952).
Born into a vaudeville family, O'Connor was the youthful figure cutting a rug in several Universal musicals of the 1940s. His best-known musical work is probably Singin' in the Rain (1952), in which he did an impressive dance that culminated in a series of backflips off the wall. O'Connor was also effective in comedic lead roles, particularly as the companion to Francis the Talking Mule in that film series.
