Vaudeville was a theatrical genre of variety entertainment in the United States and Canada from the early 1880s until the early 1930s. Each performance was made up of a series of separate, unrelated acts grouped together on a common bill. Types of acts included popular and classical musicians, dancers, comedians, trained animals, magicians, female and male impersonators, acrobats, illustrated songs, jugglers, one-act plays or scenes from plays, athletes, lecturing celebrities, minstrels, and movies. A Vaudeville performer is often referred to as a vaudevillian.

Vaudeville developed from many sources, including the concert saloon, minstrelsy, freak shows, dime museums, and literary burlesque. Called "the heart of American show business," vaudeville was one of the most popular types of entertainment in North America for several decades.

The origin of the term is obscure, but is often explained as being derived from the expression voix de ville which means "voice of the city" or "songs of the town." A second speculation is that it comes from the fifteenth century songs on satire by Olivier Basselin, "Vaux de Vire." Another plausible etymology finds origins in the French Vau de Vire, a valley in Normandy noted for its style of satirical songs with topical themes. The term vaudeville, referring specifically to North American variety entertainment, came into common usage after 1871 with the formation of Sargent's Great Vaudeville Company of Louisville, Kentucky. It had little, if anything, to do with the Comédie en vaudeville of the French theatre.

Fred Astaire (born Frederick Austerlitz; May 10, 1899 – June 22, 1987) was an American film and Broadway stage dancer, choreographer, singer and actor. His stage and subsequent film career spanned a total of 76 years, during which he made 31 musical films. He was named the fifth Greatest Male Star of All Time by the American Film Institute. He is particularly associated with Ginger Rogers, with whom he made ten films.

Gene Kelly, another major innovator in filmed dance, said that "the history of dance on film begins with Astaire". Beyond film and television, many classical dancers and choreographers, Rudolf Nureyev, Sammy Davis, Jr., Michael Jackson, Gregory Hines, Mikhail Baryshnikov, George Balanchine and Jerome Robbins among them, also acknowledged his importance and influence.

Astaire was born in Omaha, Nebraska, the son of Johanna "Ann" (née Geilus) and Frederic "Fritz" Austerlitz (born September 8, 1868, as Friedrich Emanuel Austerlitz). Astaire's mother was born in the United States to Lutheran German immigrants from East Prussia and Alsace, while Astaire's father was born in Linz, Austria, to Jewish parents who had converted to Catholicism.

Judy Garland (June 10, 1922 – June 22, 1969) was an American actress, singer and vaudevillian. Renowned for her contralto voice, she attained international stardom through a career that spanned 45 of her 47 years as an actress in musical and dramatic roles, as a recording artist and on the concert stage. Respected for her versatility, she received a Juvenile Academy Award and won a Golden Globe Award, as well as Grammy Awards and a Special Tony Award. She was nominated for the Academy Award for Best Actress for her role in the remake of A Star is Born and for Best Supporting Actress for her performance in the 1961 film, Judgment at Nuremberg. At 39 years of age, she remains the youngest recipient of the Cecil B. DeMille Award for lifetime achievement in the motion picture industry.

After appearing in vaudeville with her two older sisters, Garland was signed to Metro-Goldwyn-Mayer as a teenager. There she made more than two dozen films, including nine with Mickey Rooney and the 1939 film with which she would be most identified, The Wizard of Oz. After 15 years, she was released from the studio but gained renewed success through record-breaking concert appearances, including a return to acting beginning with critically acclaimed performances.

Eddie Cantor (January 31, 1892 – October 10, 1964), born Edward Israel Iskowitz, was an American "illustrated song" performer, comedian, dancer, singer, actor and songwriter. Familiar to Broadway, radio, movie and early television audiences, this "Apostle of Pep" was regarded almost as a family member by millions because his top-rated radio shows revealed intimate stories and amusing anecdotes about his wife Ida and five daughters. Some of his hits include "Makin' Whoopee," "Ida," "If You Knew Susie," "Ma! He's Makin' Eyes at Me," "Margie" and "How Ya Gonna Keep 'Em Down on the Farm (After They've Seen Paree?)" He also wrote a few songs, including "Merrily We Roll Along," the Merrie Melodies Warner Bros. cartoon theme.

His eye-rolling song-and-dance routines eventually led to his nickname, "Banjo Eyes." In 1933, the artist Frederick J. Garner caricatured Cantor with large round eyes resembling the drum-like pot of a banjo. Cantor's eyes became his trademark, often exaggerated in illustrations, and leading to his appearance on Broadway in the musical Banjo Eyes (1941).

Klaus Sperber (January 24, 1944 – August 6, 1983), better known as Klaus Nomi, was a German countertenor noted for his wide vocal range and an unusual, otherworldly stage persona.

Nomi was known for his bizarrely visionary theatrical live performances, heavy make-up, unusual costumes, and a highly stylized signature hairdo which flaunted a receding hairline. His songs were equally unusual, ranging from synthesizer-laden interpretations of classical music opera to covers of 1960s pop standards like Chubby Checker's "The Twist" and Lou Christie's "Lightnin' Strikes". He is remembered in the US as one of David Bowie's backup singers for a 1979 performance on Saturday Night Live.

Nomi died in 1983 at the age of 39 as a result of complications from AIDS.

Klaus Nomi was born Klaus Sperber in Immenstadt, Bavaria, Germany on January 24, 1944. In the 1960s, he worked as an usher at the Deutsche Oper in West Berlin where he sang for the other ushers and maintenance crew on stage in front of the fire curtain after performances. Around that time he also sang opera arias at the Berlin gay discothèque Kleist Casino.^{[citation needed]}
