Breon O’Casey, born in 1928 was the son of the Irish playwright, Sean O’Casey. After participating in National Service, he attended the Anglo-French Art School, which is a small art school in St John’s Wood, London, based on the French model.
He left for St Ives in the mid fifties and worked as an assistant to the sculptor, Denis Mitchell and then Dame Barbara Hepworth. He also began making jewellery as a side line, although his main occupation was and is always painting.
Breon O’ Casey continued making jewellery until he was 70 and the next 10 years were devoted solely to painting and sculpture, with the occasional session of print making.
