Arman was a French-American artist and sculptor, most commonly known for his assemblages. By preference, he used pre-fabricated materials. In 1957 he decided, in the spirit of ‘Vincent’ (van Gogh)- not to go by the name of Armand Pierre Fernandez anymore, but simply Arman.
Between 1959 and 1962 Arman developed his notorious style by introducing two new concepts: the accumulation and the poubelle. The accumulation was a collection of ordinary, identical objects, in large quantities confined together in a polyester or plexiglass case. The poubelle was a collection of scattered consumer trash, with which he filled galleries including that of Yves Klein. In October 1960 he was closely involved with the establishment of the artist-movement Nouveau Réalisme which included artists like Yves Klein, Daniel Spoerri, Jean Tinguely and later also César, Niki de Saint Phalle, Christo and others.
