Michael Kidd (born Milton Greenwald; August 12, 1915 – December 23, 2007) was an American film and stage choreographer, dancer and actor, whose career spanned five decades, and who staged some of the leading Broadway and film musicals of the 1940s and 1950s. Kidd, strongly influenced by Charlie Chaplin and Léonide Massine, was an innovator in what came to be known as the "integrated musical", in which dance movements are integral to the plot.^{[citation needed]}

He was probably best known for his athletic dance numbers in Seven Brides for Seven Brothers, a 1954 Metro-Goldwyn-Mayer musical. Film critic Stephanie Zacharek called the barn-raising sequence in Seven Brides "one of the most rousing dance numbers ever put on screen". He was the first choreographer to win five Tony Awards, and was awarded an honorary Oscar in 1996 for advancing dance in film.

Kidd was born in New York City on the Lower East Side, the son of Abraham Greenwald, a barber, and his wife Lillian, who were Jewish refugees from Czarist Russia. He moved to Brooklyn with his family and attended New Utrecht High School. He became interested in dance after attending a modern dance performance, and went on to study under Blanche Evan, a dancer and choreographer.

He studied chemical engineering at the City College of New York in 1936 and 1937, but left after being granted a scholarship to the School of American Ballet. He toured the country as a member of the corps de ballet of Lincoln Kirstein’s Ballet Caravan, and performed in roles that included the lead in Billy the Kid, choreographed by Eugene Loring, which featured an orchestral composition by Aaron Copland.

In 1942, while performing with Ballet Caravan, Milton and his fellow dancers were encouraged to adopt an "American" name. His choice of the stage name 'Kidd' as his older brother was a booking agent for the Concord Hotel in the Catskill Mountains, and Milton was always known as "the kid."

In 1941, Kidd became a soloist and assistant to Loring in his Dance Players. He became a soloist for Ballet Theater, later known as the American Ballet Theatre. His performances there included Fancy Free (1944) choreographed by Jerome Robbins and with music by Leonard Bernstein, in which he played one of the three sailors. While at the ABT, he created his own ballet, On Stage! (1945). Although the play and his performance were well received, and the New York Times observed that Kidd was "hailed as one of the great hopes of postwar American ballet," he left Loring's company for Broadway in 1947 and never again worked in ballet.

Kidd's first choreography on Broadway was for E.Y. Harburg's Finian's Rainbow, a lyrical musical that explored racial prejudice. Kidd won his first Tony Award for that play. However, his next Broadway musicals were not successful. They were Hold It, a college musical, and the Kurt Weill/Alan Jay Lerner musical Love Life, directed by Elia Kazan, which both had short runs in 1948. Next came Arms and the Girl (1950), directed by Rouben Mamoulian, with Pearl Bailey and Nanette Fabray, also a flop.

Frank Loesser’s Guys and Dolls (1950), his next play, cemented his reputation as a Broadway choreographer. It was based on Damon Runyon short stories, with book by Abe Burrows, and earned Kidd his second Tony Award. The play attracted the attention of movie producers, and he was lured to Hollywood.
