Thomas Sowerby Hamblin (14 May 1800 – 8 January 1853) was an English actor and
theatre manager. He first took the stage in England, then immigrated to the United States in 1825. He received critical acclaim there, and eventually entered theatre management. During his tenure at New York City's
Bowery Theatre he helped establish
working-class theatre as a distinct form. His policies preferred American actors and playwrights to British ones, making him an important influence in the development of early American drama.
