Robert Matta is a Chilean painter, born in 1911 and died in 2002 in Italy. He is a painter who is part of the surrealist vein, but he is also interested in architecture, sculpture and poetry. In 1933, he moved to Paris and entered Le Corbusier's studio where he stayed only a short time. Later on he moved away from the rationalism of the architect. He became a friend of André Breton and Yves Tanguy, whose influence was very important in Matta's training at that time. In his paintings, he came closer and closer to the process of automatic writing. During the war, he took refuge in New York with Marcel Duchamp and exhibited there in the Julien Levy gallery, whose specialty was the surrealist movement. It was there that Matta discovered relativistic physics and theories of the fourth dimension: he spent all his time reading the scientific press. Matta was also very politically engaged. Wars and political affairs inspired him: he painted to represent the Algerian war, the Vietnam war or the case of the Rosenberg couple convicted of spying for the USSR. Matta remained faithful to the surrealist style, but it was above all the subjects he tackled that became more diverse.
