The 'Art Fund' was launched in 1903 and it has since become Britain's leading charity for the purchase of works of art for the nation's collections. More than four hundred works have been acquired by Tate with assistance from the Art Fund. The first of these was J. M. Whistler's Nocturne in Blue and Gold: Old Battersea Bridge, acquired in 1905 and more recent acquisitions assisted by the Art Fund are Piet Mondrian's Sun, Church in Zeeland, David Smith's Wagon II and Rebecca Horn's Concert for Anarchy.
