Pierre Restany (1930-2003) was brought up in Morocco. He later studied in France, Italy and Ireland. In 1963 he worked on the art and architecture journal "Domus", and since 1985 he has edited the magazine "D'ARS". His meeting with Yves Klein in 1955 inspired his 1960 theory of "Nouveau Réalisme" and he founded an art-group of the same name in Paris. He wrote and published extensively on the art of the twentieth century.
