his life, Jürg Kreienbühl worked on the catalogue raisonné of his prints and on the monography Malerei der Leidenschaft, both published in 1998. Some important exhibitions were held at Musée de Gravelines (2011), Centre culturel Suisse in Paris (2001) and Centre d’art Jacques-Henri Lartigue in L’Isle-Adam (2006). After his death in 2007 in Cormeille-en-Parisis, his work is being progressively rediscovered and joined the collection of the Centre Georges Pompidou and the Museum of Fine Arts of Rennes in 2017. Work Although influenced at his beginnings by an expressionist manner like Lovis Corinth or Chaïm Soutine, his work turned quite quickly to an uncompromising realism. Willing to show the reality in the raw, he made himself the witness or the chronicler of the end times, by documenting the condemned worlds by the evolution of society : the old beliefs, the social outcasts and the life in the fringe and the ravages from urbanization and industrialization. According to Le Monde art critic Philippe Dagen, Jürg Kreienbühl "could be seen as the first photorealist of the Parisian painting in the 1960s. He can also be seen as the predecessor of those who make their art a disillusioned social and architectural chronicle". His realist approach does not aim to reproduce strictly his natural environment but "to go beyond reality through the reality"as written by Leonard Ginsburg. His conception of realism has to be linked to his use of LSD in his youth, under the supervision of his friend Albert Hofmann who evoke it in his book "LSD - My Problem Child". Since this experiment, the visible world is for the painter the vehicle of another reality, hidden, omnipresent but invisible. That's why Albert Hoffman wrote about him that he was "both a painter and mystic".
