John Petts (1914-1991) was a British artist. Petts was born in London, England but is considered a Welsh artist and is known for his engravings and stained glass works. A British Institution scholarship allowed Petts to study at the Royal Academy Schools for two years from 1933, during which time he also took evening classes in printing at the Central School of Arts and Crafts. In 1935 Petts married the artist Brenda Chamberlain in London and the couple set up home near Llanllechid in north Wales, where they held two joint exhibitions of their art and supported themselves by creating and selling greeting cards and doing some part-time teaching in Bangor. With Chamberlain, Petts bought a hand operated printing press and set up the Caseg Press in 1937 to produce bookplates, greeting cards and prints of local scenes. Petts collaborated with the poet Alun Lewis on illustrations for a number of Welsh-language magazines before the latter died in the Second World War. At the start of the war Petts had registered as a conscientious objector and was required to undertake farm work away from Wales. Petts and Chamberlain separated in 1943 after which Petts volunteered to join a Royal Army Medical Corps Parachute Field Ambulance unit. Returning to Wales Petts and his second wife Kusha Petts sought to restart the Caseg Press and also undertook work for the Golden Cockerel Press. He helped to design the Lloyd George Museum at Llanystumdwy which for a time housed the Caseg Press's printing press. In 1951 Petts took a series of posts with the Welsh Committee of the Arts Council. Petts was elected to the Society of Wood Engravers in 1953 and became an Associate of the Royal Society of Painter-Etchers & Engravers in 1957. Taking a post as a lecturer in design and crafts at the Carmarthen School of Art in 1957 allowed him to concentrate on working in stained-glass. In later life Petts lived and worked in Abergavenny in the southeast of Wales.
