(b Verona, 10 Dec. 1905; d Milan, 3 May 1959).
Italian painter whose outspoken political views and advanced and energetic artistic outlook gave him a prominent place in his country's avant-garde. His early work was Expressionist, influenced by Ensor and van Gogh, and a visit to Paris in 1936 introduced him to the work of the Fauves. In 1938 he was one of the founders of the anti-Fascist Corrente organization; he published articles in many journals and was persecuted and imprisoned for his political activities. After the Second World War he was strongly influenced by Picasso and gradually moved towards abstraction, his work eventually coming within the orbit of Art Informel. In 1947 he joined the Fronte Nuovo delle Arti. From 1948 his work was shown at the Venice Biennale on several occasions and was much exhibited elsewhere in Italy.
