The playhouse was founded in 1931 by Langner and his wife, Armina Marshall.

In addition to the playhouse, Langner founded the Theatre Guild, which produced “Oklahoma!” and “Porgy and Bess,” among many other plays and musicals. He also helped to establish the American Shakespeare Festival Theater, the American Repertory Company and the “U.S. Steel Hour.”

Langner also was the author of several plays and books, including his autobiography, “The Magic Curtain,” recounting his life in the theater as well as his other career as a patent attorney.
