Dancer and Actress. She started dancing as a child being taught by her father, Ernest Belcher, who founded the Celeste School of Dance where he taught the likes of Astaire, Shirley Temple, Cyd Charisse and Joan Crawford and worked for director Cecil B. DeMille. She studied exclusively with him from the age of five until she left for New York. In 1930, she made her debut in the Hollywood Bowl at age 11 in the ballet "Carnival in Venice." She became a ballet instructor at her father's studio at the age of 12. The Walt Disney Studio hired her as a dance model for their animated films when she was 14. She worked on "Snow White and the Seven Dwarfs" (1937) and her movements were copied to enhance the realism of the animated Snow White figure. She later modeled for characters in other animated films including the Blue Fairy in "Pinocchio" (1940) and Hyacinth Hippo in the Dance of the Hours segment of "Fantasia," a ballet parody that she also helped choreograph. She also did some modeling for Mr. Stork in "Dumbo." The first film she appeared in was "The Castles" with Fred Astaire and Ginger Rogers. Together as a dance team, she and her second husband, Gower Champion, performed in MGM musicals of the 1940s and 1950s, including "Till the Clouds Roll By" (1946), "Show Boat" (1951) and "Everything I Have Is Yours" (1952). Other films with Gower included "Mr. Music" (1950, with Bing Crosby), "Give a Girl a Break" (1953), "Jupiter's Darling" (1955), and "Three for the Show" (1955). MGM wanted the couple to remake Fred Astaire and Ginger Rogers films, but only one, "Lovely to Look At" (1952), a remake of "Roberta" (1935), was completed. The couple refused to remake any of the others, the rights to which were still owned by RKO. During the summer of 1957, they had their own TV series, "The Marge and Gower Champion Show," a situation comedy with song and dance numbers. Marge played a dancer and Gower a choreographer. Drummer Buddy Rich was featured as a fictional drummer named Cozy. In 1978 she served as a dialogue and movement coach for the TV miniseries, "The Awakening Land," adapted from Conrad Richter's trilogy of the same name. She also worked as a dance instructor and choreographer in New York City. In 1982, she made a rare television acting appearance on the dramatic TV series "Fame," playing a ballet teacher with a racial bias against African-American students. On Broadway, she appeared in several musicals and plays. She made her New York debut in "What's Up" (1943). She also performed in the "Dark of the Moon" (1945) as the Fair Witch, and "Beggar's Holiday" (1946) having multiple roles. She made her last Broadway appearance in "3 for Tonight" in 1955. She also worked as a choreographer or assistant, including in "Lend an Ear" (1948) as assistant to the choreographer; "Make a Wish" (1951), as assistant to Gower Champion; "Hello, Dolly!" (1964) as special assistant; and "Stepping Out" (1987) as choreographic associate. In 2001, she appeared as Emily Whitman in the Broadway stage revival of "Follies." She choreographed "Whose Life Is It Anyway?," "The Day of the Locust," and received an Emmy for "Queen of the Stardust Ballroom." She became a centenarian in September 2019.
