Italian sculptor and designer, born at Orciano di Pesaro. He was self-taught as a sculptor and like his brother Arnaldo worked as a jeweller early in his career. He settled in Milan in 1953 and had his first exhibition in Florence in 1954. In 1959 he won the Sculpture Prize at the Paris Biennale. His work was varied, but he was best known for abstract reliefs. In his Surfaces in Tension series (begun 1958) he used stretched fabric and tried to integrate the surface of the piece with the surrounding space. He was a member of Continuità.
