The man known as the “Father of Pop Art” has died in Britain. He was 89 years old.

British artist Richard Hamilton died Tuesday. The Gagosian Gallery, which represented Hamilton, confirmed his passing but did not disclose the location or cause of his death.

Hamilton was best known for his pop art collages, and was considered to be Britain's answer to American artist Andy Warhol. He first made his mark in the 1950s with a collage entitled “Just What Is It That Makes Today's Homes So Different, So Appealing?”

Hamilton also was well known for a variety of art projects, including the album design of the Beatles White Album in 1968, and depictions of celebrities and politicians.
