Richard Hamilton was often called the ''Father of Pop Art".

LONDON: Richard Hamilton's gallery says the British Pop Art pioneer has died. He was 89.

The Gagosian Gallery says Hamilton died early Tuesday. It did not disclose the cause.

Hamilton was often called the ''Father of Pop Art,'' a movement marked by its ironic and iconic use of pop-culture imagery.

He made his name in the 50s with ''Just What Is It That Makes Today's Homes So Different, So Appealing?'' —a collage showing a naked couple in a product-strewn home.

His images were striking and often political, from Mick Jagger in handcuffs to Tony Blair as a cowboy.

The gallery said that Hamilton had been working on a major retrospective that will travel to Los Angeles, Philadelphia, London and Madrid in 2013-14.

He is survived by his wife, Rita Donagh, and son Rod.
