Both pacifists, Jonah Jones and John Petts were in the same parachute unit during World War Two, where they met in 1944. A multi-talented artist, sculptor, teacher and publisher, Petts had studied at Hornsey College of Art, the Royal Academy and Central School of Arts and Crafts. In 1934 he moved to Llanllechid, in a remote part of Wales, where with his first wife, the artist and writer Brenda Chamberlain, he founded the Caseg Press, which published prints with local Welsh themes.
After the war, with his second wife, the artist and writer Marjory (Kusha) Miller, he restarted the Caseg Press in Llanystumdwy, near Cricieth, where from 1948–1949 Jonah joined him as his assistant.
From the early 1960s Petts was mainly preoccupied with stained-glass design. Among his most notable commissions were windows for the 16th Street Baptist Church in Birmingham, Alabama, and the 40-foot windows for the Brighton and Hove Synagogue. He exhibited widely as a painter, sculptor, designer, artist in mosaic, and craftsman. His work is in many public collections, including the National Library of Wales in Aberystwyth, Derby Art Gallery, and the University of Hong Kong.
