Ken Tyler, an American print publisher who has worked with leading contemporary artists since the 1960s, has donated 460 prints to the Tate Gallery in London.
The gift of works by 28 artists, including David Hockney, James Rosenquist, Joan Mitchell and Michael Heizer, is the largest donation of prints ever received by the gallery and the final installment in a series of gifts from Tyler's collection to museums around the world.
Tyler, who began printmaking in Chicago, co-founded Gemini G.E.L., a Los Angeles fine art publishing house, with businessmen Sidney Felsen and Stanley Grinstein in the mid-1960s. He moved to New York state in 1974, set up Tyler Graphics and retired four years ago.
Tyler told the London Independent that the Tate gift helped to fulfill his mission to "make sure that great prints are seen and appreciated by the greatest number of people possible."
