The Shubertbrothers were theatrical managers and producers of the largest theater empire in the 20th century.
The rapid growth of the Shubert Company was a threat to the Syndicate, a group of producers and theater owners who literally controlled American theater in the early 20th century.
While the brothers had essentially formed their own trust and were in constant litigation, the Shuberts did introduce to the stage many of the finest actors of the time, including the Marx Brothers, Will Rogers, Jack Benny, Al Jolson, Eddie Cantor, Bert Lahr, the Barrymores, Spencer Tracy, and dozens more.
