Perhaps Hamblin's greatest influence was in his incubation of American talent. He helped start the careers of many young unknowns, and he was not shy about exerting his influence over those who relied upon his patronage. His Bowery featured many big-name talents, including Junius Brutus Booth, Frank Chanfrau, George Washington Dixon, Louisa Lane Drew, Edwin Forrest, Josephine Clifton, Louisa Medina, James B. Phillips, Thomas D. Rice, and Charles W. Taylor. In 1831, he renamed the playhouse "the American Theatre, Bowery" after an anti-British riot at the Park Theater. The message was clear: The Bowery was the theatre of Native American drama.
