Peter Coker was born in London in 1926. He would study during his early career at St Martins College of Art and would later go on to the Royal College of Art where he was greatly admired, winning a number of scholarships during his tenure. His work was linked to the 'Kitchen Sink movement' whose proponents were artists such as John Bratby.
He was given multiple solo shows at the Zwemmer Gallery, the Thackeray Gallery, and Gallery 10. He was also an ardent fixture at the Royal Academy summer shows. He would eventually be given the Royal Academician status in 1972.
His work is held in the National collection at the Tate and in many other local and international Museums.
