Otto Müller (16 October 1874 – 24 September 1930) was a German painter and printmaker of the Die Brücke expressionist movement.

[citation needed] Mueller was known as incredibly antibourgeois and is said to have urinated on the floor of a middle-class household when he was invited for a dinner party.

After the war he became a professor at the Academy of Arts (Akademie der Bildenden Kunste) in Breslau where he taught until his death on 24 September 1930.

The main topic of Mueller's works is the unity of humans and nature; his paintings emphasize a harmonious simplification of form, colour and contours.

[3] Mueller was a huge fan of Egyptian art, and likened his use of simple clean lines to the ancient style.
