The Group Theatre was a theater collective based in New York City and formed in 1931 by Harold Clurman, Cheryl Crawford and Lee Strasberg. It was intended as a base for the kind of theatre they and their colleagues believed in—a forceful, naturalistic and highly disciplined artistry. They were pioneers of what would become an "American acting technique", derived from the teachings of Konstantin Stanislavski, but pushed beyond them as well. The company included actors, directors, playwrights, and producers. The name "Group" came from the idea of the actors as a pure ensemble; a reference to the company as "our group" led them to "accept the inevitable and call their company The Group Theatre."

Harold Edgar Clurman was an American theatre director and drama critic. In 2003, he was named one of the most influential figures in U.S. theater by PBS. He was one of the three founders of New York City's Group Theatre (1931–1941). He directed more than 40 plays in his career and, during the 1950s, was nominated for a Tony Award as director for several productions. In addition to his directing career, he was drama critic for The New Republic (1948–1952) and The Nation (1953–1980), helping shape American theater by writing about it. Clurman wrote seven books about the theatre, including his memoir The Fervent Years: The Group Theatre and the Thirties (1961).
