Painter. Self-taught, he began painting in the early 1930's. He debuted around 1940, becoming part of the 'Corrente' group. In 1946 he published the manifesto Beyond Guernica, and then joined the 'Fronte Nuovo delle Arti', declaring his interest in abstract art. In 1952 L. Venturi presented him to the Eight Painters group. With an emerging dynamic style and interrupting the pictorial plane (Plurimi [Multiples]) he became an important figure in the European Art Informel movement.
