(b. London, 15 Jan. 1879; d. London, 4 Jan. 1961) Character actor, particularly known as a performer of high comedy. Thesiger trained initially as an artist, but quickly discovered he preferred acting. He worked initially under George Alexander and Beerbohm Tree, then from 1915 appeared in the farce A Little Bit of Fluff, which ran for over three years. After the First World War, Thesiger became one of Shaw's most valued actors. Shaw created several roles for him, including the Dauphin in St Joan. His memoir, Practically True, appeared in 1927.
