Best known for his kaleidoscopic dance sequences, Busby Berkeley (1895-1976) was a highly-influential director and choreographer of movie musicals. Born in Los Angeles, California as William Berkeley Enos, he served in World War I as a director of parade drills; most credit his involvement with the military for the patterns that would categorize his later work.Berkeley was known for his single-camera takes, which he developed during his first stint as a director. Unsatisfied with the protocol wherein choreographers created dance sequences, but had little control over camera placement and editing choices, Berkeley convinced film producer Samuel Goldwyn to allow him to try his hand at directing. The result was so visually stunning that Berkeley was given a seven year contract, and would continue to contribute musical numbers to almost all of the major productions coming out of Warner Brothers during the 1930s. Some of his most famous works include 42nd Street (1933), Gold Diggers of 1933 (1933), and Footlight Parade (1933). In all of these films, Berkeley used hundreds of dancers to create awe-inspiring, geometric spectacles.
