George Orson Welles was born May 6, 1915, in Kenosha, Wisconsin, son of Richard Head Welles (b. Richard Hodgdon Wells, November 12, 1872, near St. Joseph, Missouri; d. December 28, 1930, Chicago, Illinois) and Beatrice Ives Welles (b. Beatrice Lucy Ives, September 1, 1883, Springfield, Illinois; d. May 10, 1924, Chicago).

Breaking with the Federal Theatre Project in 1937, Welles and Houseman founded their own repertory company, which they called the Mercury Theatre. The name was inspired by the title of the iconoclastic magazine, The American Mercury. Welles was executive producer, and the original company included such actors as Joseph Cotten, George Coulouris, Geraldine Fitzgerald, Arlene Francis, Martin Gabel, John Hoyt, Norman Lloyd, Vincent Price, Stefan Schnabel and Hiram Sherman.  "I think he was the greatest directorial talent we've ever had in the [American] theater," Lloyd said of Welles in a 2014 interview. "When you saw a Welles production, you saw the text had been affected, the staging was remarkable, the sets were unusual, music, sound, lighting, a totality of everything. We had not had such a man in our theater. He was the first and remains the greatest."  The Mercury Theatre opened November 11, 1937, with Caesar, Welles's modern-dress adaptation of Shakespeare's tragedy Julius Caesar -- streamlined into an anti-fascist tour de force that Joseph Cotten later described as "so vigorous, so contemporary that it set Broadway on its ear." The set was completely open with no curtain, and the brick stage wall was painted dark red. Scene changes were achieved by lighting alone. On the stage was a series of risers; squares were cut into one at intervals and lights were set beneath it, pointing straight up to evoke the "cathedral of light" at the Nuremberg Rallies. "He staged it like a political melodrama that happened the night before," said Lloyd.  Beginning January 1, 1938, Caesar was performed in repertory with The Shoemaker's Holiday; both productions moved to the larger National Theatre. They were followed by Heartbreak House (April 29, 1938) and Danton's Death (November 5, 1938). As well as being presented in a pared-down oratorio version at the Mercury Theatre on Sunday nights in December 1937, The Cradle Will Rock was at the Windsor Theatre for 13 weeks (January 4-April 2, 1938). Such was the success of the Mercury Theatre that Welles appeared on the cover of Time magazine, in full makeup as Captain Shotover in Heartbreak House, in the issue dated May 9, 1938--three days after his 23rd birthday.
