Born in Rome in 1926, he lived in Milan where he trained at the Brera Fine Arts Academy and then studied at the Milan University. He taught as professor of sculpture at the Brera Academy for 31 years. As sculptor he often broke, but not always, the rules and infringed the approved technology, for his own expression, communication and aesthetic needs in language.
During his 40 years activity, he used many different materials: from the traditionally metals used in sculpture, like copper, bronze, silver to the less traditional ones: steel, cast-iron, brass,lead, imitation-gold. He then used a variety of plastics, paper, words, sound, fabrics, wood, water, artifacts and objects trouvés, porcelain, ceramics, terra-cotta, glass, mirrors and recovered materials too.
In Los Angeles he worked on the "trace," on "void," leaving the absence of a work, in order to provoke, to stimulate one's memory, the remembrance of something that had happened before, something that was. His first solo show, in 1951, was followed by many around the world. He died in Milan in 1998.
