Robert Alton was an American dancer and choreographer, a major figure in dance choreography of Broadway and Hollywood musicals from the 1930s through to the early 1950s. He is principally remembered today as the discoverer of Gene Kelly, for his collaborations with Fred Astaire, and for choreographic sequences he designed for Hollywood musicals such as The Harvey Girls (1946), Till the Clouds Roll By (1946), Show Boat (1951), and White Christmas (1954).

Eugene Curran Kelly was an American dancer, actor, singer, director and choreographer. He was known for his energetic and athletic dancing style and sought to create a new form of American dance accessible to the general public, which he called "dance for the common man". He starred in, choreographed, and co-directed with Stanley Donen some of the most well-regarded musical films of the 1940s and 1950s.
