The British sculptor Henry Moore expressed an interest in sculpture at an early age. After serving in the army in World War I (1917–1919), he studied at the Leeds School of Art. In 1925 he toured France and Italy on a scholarship. He then taught at the Royal College of Art, London, until 1932, when he became head of the sculpture department at the Chelsea School of Art (until 1939). Moore’s first one-man show was at London’s Warren Gallery in 1928, followed by other exhibitions and public commissions. Influenced by primitive art and surrealism, his work became more abstract, and in the 1930s he associated with several artist groups, including the Seven and Five Society (later the Seven and Five Abstract Group) and Unit One. During World War II he was commissioned to do a series of drawings depicting people seeking shelter in the London Underground. At first Moore mostly worked in wood and stone, while his later sculptures were often in cast metal. His subjects included reclining figures, family groups, and abstract, organic forms. In 1977 he established the Henry Moore Foundation, which encourages public appreciation of the visual arts. Throughout his career Moore earned many important prizes and retrospective exhibitions.
