The Follies were produced and managed by Florenz Ziegfeld (1869-1932).
The Follies were lavish reviews, something in between later Broadway shows and a more elaborate high class Vaudeville variety show. Many of the top entertainers of the era appeared in the shows. The Ziegfeld Follies were also famous for many beautiful chorus girls.
After Flo Ziegfeld's death, his widow authorized use of his name for Ziegfeld Follies of 1934 and 1936. The name was later used by other promoters with less connection to the original Follies.
