Barnett, Samuel Augustus, 1844-1913, English clergyman and social worker. As vicar of St. Jude's, Whitechapel, in the slums of London, he pioneered in the social settlement movement. Toynbee Hall, the first settlement house, was opened in 1884 with Barnett as its first warden. He was also active in the university extension movement. His wife, Henrietta Octavia Barnett, 1851-1936, was especially interested in housing and helped found a model garden suburb at Hampstead. She collaborated in some of her husband's books, notably Practicable Socialism (1888) and wrote his biography (1918). In 1924 she became Dame Commander of the British Empire.
