Sir Herbert Beerbohm Tree (17 December 1852 – 2 July 1917) was an English actor and theatre manager.
Tree began performing in the 1870s. By 1887, he was managing the Haymarket Theatre in the West End, winning praise for adventurous programming and lavish productions, and starring in many of its productions. In 1899, he helped fund the rebuilding, and became manager, of His Majesty's Theatre. Again, he promoted a mix of Shakespeare and classic plays with new works and adaptations of popular novels, giving them spectacular productions in this large house, and often playing leading roles. His wife, actress Helen Maud Holt, often played opposite him and assisted him with management of the theatres.
Although Tree was regarded as a versatile and skilled actor, particularly in character roles, by his later years his technique was seen as mannered and old-fashioned. He founded the Royal Academy of Dramatic Art in 1904 and was knighted for his contributions to theatre in 1909. His famous family includes his siblings, explorer Julius Beerbohm, author Constance Beerbohm and half-brother caricaturist Max Beerbohm. His daughters were Viola, an actress, Felicity, a socialite and Iris, a poet. His illegitimate children included film director Carol Reed. He was a grandfather of the actor Oliver Reed.
