Mixed-Media Sigmar Polke
Sigmar Polke (13 February 1941 – 10 June 2010) was a German painter and photographer.
Polke experimented with a wide range of styles, subject matters and materials. In the 1970s, he concentrated on photography, returning to paint in the 1980s, when he produced abstract works created by chance through chemical reactions between paint and other products. In the last 20 years of his life, he produced paintings focused on historical events and perceptions of them.Wikipedia
In 1963, Polke founded the painting movement "Kapitalistischer Realismus" ("Capitalist realism") with Gerhard Richter and Konrad Fischer (alias Konrad Lueg as artist). It is an anti-style of art, appropriating the pictorial shorthand of advertising. This title also referred to the realist style of art known as "Socialist Realism", then the official art doctrine of the Soviet Union and its satellites (from one which he had fled with his family), but it also commented upon the consumer-driven art "doctrine" of western capitalism. He also participated in "Demonstrative Ausstellung", a store-front exhibition in Düsseldorf with Manfred Kuttner, Lueg, and Richter. Essentially a self-taught photographer, Polke spent the next three years painting, experimenting with filmmaking and performance art.Wikipedia
