Adolf Wölfli is the emblematic figure of 20th century art brut, author of more than 1,500 drawings and of a 25,000-page biography. He has built a personal and complex universe, where he reinvents his past and projects a utopian future, colonized to the edge of space. The richness and excess of this work cause vertigo. The list of artists he fascinates is long (among them Jean Dubuffet, Annette Messager, Arnulf Rainer), and an echo to his presence in the collections of the Musée National d’Art Moderne (France), Prinzhorn collection (Germany), and the LaM (France). As André Breton pointed out, this is “one of the three or four major works of the 20th century.”
