Florenz Edward Ziegfeld Jr. (March 21, 1867 – July 22, 1932), popularly known as Flo Ziegfeld, was an American Broadway impresario, notable for his series of theatrical revues, the "Ziegfeld Follies" (1907–1931), inspired by the "Folies Bergère" of Paris.
 He also produced the musical "Show Boat".
 He was known as the "glorifier of the American girl".
 Ziegfeld is a member of the American Theater Hall of Fame.
Irvin Colloden Miller (February 19, 1884 – February 27, 1975) was an African-American actor, playwright and vaudeville show writer and producer.
 He was responsible for successful theater shows including "Broadway Rastus" (1921), "Liza" (1922), "Dinah" (1923), which introduced the wildly popular black bottom dance, and "Desires of 1927" starring Adelaide Hall.
 For thirty years he directed the popular review, "Brown Skin Models", influenced by the "Ziegfeld Follies" but exclusively using black performers.
 "In the 1920s and 1930s, he was arguably the most well-established and successful producer of black musical comedy."
A Parisian Model is a 1906 Edwardian musical comedy with music by Max Hoffman, Sr. to a book and lyrics by Harry B. Smith.
 The story concerns a dressmaker's model who comes into a fortune.
 It opened on Broadway in 1906, ran with success and toured.
 It was produced by Frank McKee and Florenz Ziegfeld Jr., and starred Anna Held, Ziegfeld's common law wife.
 Soon after the success of this piece, Ziegfeld would launch his famous series of "Ziegfeld Follies" revues.
Vera Michelena (June 16, 1885 – August 28, 1961) was a Venezuelan American actress, contralto prima donna and dancer who appeared in light opera, musical comedy, vaudeville and silent film.
 She was perhaps best remembered for her starring rôles in the musicals "The Princess Chic", "Flo Flo" and "The Waltz Dream", her rendition of the vampire dance in the musical "Take It From Me" and as a "Ziegfeld Follies" performer.
Sally is a musical comedy with music by Jerome Kern, lyrics by Clifford Grey and book by Guy Bolton (inspired by the 19th century show, "Sally in our Alley"), with additional lyrics by Buddy De Sylva, Anne Caldwell and P. G. Wodehouse.
 The plot hinges on a mistaken-identity: Sally, a waif, is a dishwasher at the Alley Inn.
 She poses as a famous foreign ballerina and rises to fame (and finds love) through joining the Ziegfeld Follies.
 There is a rags to riches story, a ballet as a centrepiece, and a wedding as a finale.
 "Look for the Silver Lining" continues to be one of Kern's most familiar songs.
 The song is lampooned by another song, "Look for a Sky of Blue," in Rick Besoyan's satirical 1959 musical "Little Mary Sunshine".
Helen Barnes (1895–1925) was an American musical comedy actress and Ziegfeld Follies Girl.
Glorifying the American Girl is a 1929 American Pre-Code, musical comedy film produced by Florenz Ziegfeld that highlights Ziegfeld Follies performers.
 The last third of the film (which was filmed in early Technicolor) is basically a Follies production, with cameo appearances by Rudy Vallee, Helen Morgan, and Eddie Cantor.
Mary Nolan (December 18, 1902 – October 31, 1948) was an American stage and film actress, singer and dancer.
 She began her career as a Ziegfeld girl in the 1920s performing under the stage name Imogene "Bubbles" Wilson.
 She was fired from the "Ziegfeld Follies" in 1924 for her involvement in a tumultuous and highly publicized affair with comedian Frank Tinney.
 She left the United States shortly thereafter and began making films in Germany.
 She appeared in seventeen German films from 1925 to 1927 using a new stage name, "Imogene Robertson".
Lucille Bremer (February 21, 1917 – April 16, 1996) was an American film actress and dancer.
