Carl Olaf Plate (1909 – 1977) was an Australian modernist painter and collage artist. He was born in Perth in 1909 and studied at the East Sydney Technical College before travelling to Europe in 1935. He studied at the Central School of Arts and Crafts in London and was influenced by Vivian Pitchforth's ideas on 'holistic composition.' Plate established the Notanda Gallery in Sydney and curated numerous exhibitions there between 1940 and 1943. He had 28 solo exhibitions in his lifetime and was the first Australian non-figurative artist to have solo exhibitions in London and New York. His collages and paintings are represented in many collections, including the National Gallery of Australia and the Art Gallery of New South Wales. Plate died in Woronora in 1977.
