Max Ernst was born on April 2, 1891, in Brühl, Germany. He enrolled in the University at Bonn in 1909 to study philosophy, but soon abandoned this pursuit to concentrate on art. At this time he was interested in psychology and the art of the mentally ill. In 1911 Ernst became a friend of August Macke and joined the Rheinische Expressionisten group in Bonn. Ernst showed for the first time in 1912 at the Galerie Feldman in Cologne. At the Sonderbund exhibition of that year in Cologne he saw the work of Paul Cézanne, Edvard Munch, Pablo Picasso, and Vincent van Gogh. In 1913 he met Guillaume Apollinaire and Robert Delaunay and traveled to Paris. Ernst participated that same year in the Erste deutsche Herbstsalon. In 1914 he met Jean Arp, who was to become a lifelong friend.
