Rejected by the Munich Art Academy and the Berlin Secession, Otto Mueller became - despite all adversities - one of the most important painters of German Expressionism. As co-founder of the New Secession and a member of the "Brücke" group of artists, Mueller was an integral part of the avant-garde, and yet he embarked on his very own artistic career. His main themes include slender nudes of girls as well as gypsy motifs. Due to the greatly simplified forms, the clear structure and the muted colors, his work does indeed play a special role among his artist colleagues. A characteristic of his paintings for example, is the use of distemper paint as well as burlap for the painting surface. Striving to express feelings with the greatest possible simplicity can be identified as one of his central artistic motifs. Mueller finally made a name for himself in the field of lithography with his so-called "Gypsy Portfolio", completed in 1927. Posthumously, his work was declared degenerate under the Nazi regime and many of his works were confiscated.
