Swedish abstract painter and sculptor, born in Halmstad. Has lived in Stockholm since 1928. Earned his living for many years by working in a bank, painting in his spare time. Painted in 1938 in a nordic expressionist style, then in 1939 turned to Matisse. In the mid 1940s began to develop towards abstraction. Visited Paris in 1948 and worked first with Lhote, then with Léger. Started in 1949 to paint completely abstract pictures with unbroken areas of colour and distinct lines, and experimented briefly with circles and after-images; first one-man exhibition at the Galerie Samlaren, Stockholm, 1949. Met Herbin in Paris in 1950 and joined the Réalités Nouvelles. Began in 1951 to use oblique rather than horizontal-vertical lines, and since 1954 has worked exclusively with open acute angles to achieve open form. Has also made sculptures since 1954 and from 1958 has worked on painting and sculpture side by side, regarding them as identical expressions. Lives in Stockholm.
