with Surrealist techniques. However, Conroy Maddox, one of the first British Surrealists whose work in this genre dated from 1935, remained within the movement, and organized an exhibition of current Surrealist work in 1978 in response to an earlier show which infuriated him because it did not properly represent Surrealism. Maddox's exhibition, titled Surrealism Unlimited, was held in Paris and attracted international attention. He held his last one-man show in 2002, and died three years later. Magritte's work became more realistic in its depiction of actual objects, while maintaining the element of juxtaposition, such as in 1951's Personal Values (Les Valeurs Personnelles) and 1954's Empire of Light (L’Empire des lumières). Magritte continued to produce works which have entered artistic vocabulary, such as Castle in the Pyrenees (Le Château des Pyrénées), which refers back to Voix from 1931, in its suspension over a landscape. Other figures from the Surrealist movement were expelled. Several of these artists, like Roberto Matta (by his own description) "remained close to Surrealism". After the crushing of the Hungarian Revolution of 1956, Endre Rozsda returned to Paris to continue creating his own word that had been transcended the surrealism. The preface to his first exhibition in the Furstenberg Gallery (1957) was written by Breton yet. Many new artists explicitly took up the Surrealist banner. Dorothea Tanning and Louise Bourgeois continued to work, for example, with Tanning's Rainy Day Canape from 1970. Duchamp continued to produce sculpture in secret including an installation with the realistic depiction of a woman viewable only through a peephole. Breton continued to write and espouse the importance of liberating the human mind, as with the publication The Tower of Light in 1952. Breton's return to France after the War, began a new phase of Surrealist activity in Paris, and his critiques of rationalism and dualism found a new audience. Breton insisted that Surrealism was an ongoing revolt against the reduction of humanity to market relationships, religious gestures and misery and to espouse the importance of liberating the human mind. Major exhibitions of the 1940s, '50s and '60s 1942 – First Papers of Surrealism – New York – The Surrealists again called on Duchamp to design an exhibition. This time he wove a 3-dimensional web of string throughout the rooms of the space, in some cases making it almost impossible to see the works. He made a secret arrangement with an associate's son to
