His circle of friends in Cornwall included artists such as Bryan Wynter, Roger Hilton, the poet W.S. Graham and the novelist John le Carré. He also became friends with Francis Bacon during his stay in Cornwall in 1959 - 60.
He is best known for his paintings which are mostly figurative although monumental and raw with nature in form. They are both exposed and challenging like the landscape in which he lived. Weschke remained notionally stateless after the war, as he did not want to go back to Germany and did not apply for British citizenship - displaced within his own landscape. He was inspired by, although not committed to, expressionism, and later developed a pared down painted surface style.
Available here are a selection of prints and etchings from the estate of Karl Weschke. These include images familiar from his painted works, and which retain a sense of the monumental. The Fire Eater is an etching of the subject which formed the lead image for his major solo exhibition at Tate St Ives in 2004 Beneath Black Sky - paintings and drawings 1953 - 2004.
