The Tate Members was founded in 1958 to raise money for the purchase of works of art across the range of the Tate collection, as well as to create wider support for Tate and to promote its aims to the general public. The first of the nearly four hundred works presented by the Tate Members was Henry Moore's sculpture King and Queen, acquired in 1959. Henri Matisse's The Snail was acquired through the Friends in 1962 and they have also assisted with other notable purchases, among them John Constable's The Opening of Waterloo Bridge, Gawen Hamilton's, The Du Cane and Boehm Family Group, Joseph Wright of Derby's Vesuvius in Eruption, Stanley Spencer's Zacharias and Elizabeth, Pablo Picasso's Weeping Woman and Andreas Gursky's Parliament.
