Wols was the pseudonym of Alfred Otto Wolfgang Schulze (27 May 1913, Berlin – 1 September 1951, Paris), a German painter and photographer predominantly active in France. Though broadly unrecognized in his lifetime, he is considered a pioneer of Lyrical Abstraction, one of the most influential artists of the Tachisme movement. He is the author of a book on art theory entitled Aphorismes de Wols.
