Helmut Sturm was a German painter.
From 1952 to 1958, he studied at the Akademie der Bildenden Künste, Munich. After this he joined Heimrad Prem, Lothar Fischer and Hans-Peter Zimmer in founding Gruppe SPUR, which in 1959 entered the Situationist International.
From 1980 to 1982, he was guest professor at the Hochschule der Künste, Berlin, taking over Hann Trier's class. He continued to exhibit across Germany and from 1985 to 1998 was professor at the Akademie der Bildenden Künste, Munich.
Hann Trier was a German abstract expressionist watercolourist and graphic artist. Hann Trier is best known for his giant ceiling paintings in the Charlottenburg Palace. He was the older brother of the art historian Eduard Trier (1920-2009).
Norbert Prangenberg was an abstract painter, sculptor, and engraver. Though he had no formal training and did not fully engage with art until his 30s, Prangenberg did finally come up with a style that was uniquely his own, not fitting comfortably into the neo-expressionist or neo-geo movements of his time, in the 1970s and 1980s. At this time, he was considered a major figure in contemporary German art. Though he got his start with abstract paintings, he also became known for making sculptures of all sizes; and while his work initially appears abstract, the titles given sometimes allude to the human body or a landscape. As a trained gold- and silversmith, as well as a glassblower, he always showed an attention to materials and how they could be physically engaged with. He was interested in how his own two hands could affect the painting or sculpture's surface. Traces of the artist's hand appear literally throughout his entire oeuvre, before he lost the battle with liver cancer in 2012.
