Karl Otto Götz often simply called K.O. Götz, was a German artist, filmmaker, draughtsman, printmaker, writer and professor of art at the Kunstakademie Düsseldorf. He was one of the oldest living and active artists older than 100 years of age and is best remembered for his explosive and complex abstract forms. His powerful, surrealist-inspired works earned him international recognition in exhibitions like documenta II in 1959. Götz never confined himself to one specific style or artistic field. He also explored generated abstract forms through television art. Götz is one of the most important members of the German Art Informel movement. His works and teachings influenced future artists such as Sigmar Polke, Nam June Paik and Gerhard Richter. He lived in Wolfenacker from 1975 until his death.
