McCaull Comic Opera Company, sometimes called the McCaull Opera Comique Company, was founded by Colonel John A. McCaull in 1880. The company produced operetta, comic opera and musical theatre in New York City and on tour in the eastern and midwestern U.S. and Canada until McCaull's death in 1894. It nurtured such stars, in their early careers, as Lillian Russell and DeWolf Hopper.
