Karl Mostböck was born on April 12, 1921 in Grein/Danube. Basically, Mostböck was a self-educated artist. He only got suggestions and training for his artistic work by Professor Gerhardinger (Munich Academy of Arts) and by the English painter of mountain scenery, Harrison Compton. In 1946, Mostböck joined the professional association of Upper Austrian artists. In 1949, he moved to Steyr and began his occupation as a graphic artist in the technical department of “Steyrer Werke”. From 1954 on, he participated in the Austrian graphic competition and was accepted for the exhibition together with artists like Alfred Kubin, Kurt Moldovan, Kurt Absolon, Alfred Hrdlicka, Hans Fronius, Adolf Frohner. In 1955, he first travelled to Paris, where he was influenced by the works of Jean Dubuffet, Jean Fautrier and Francois Desnoyer. This considerable influence of the “School of Paris”, especially of the works of Alfred Manessier, turned Mostböck into an enthusiast of the “Art of Informel”. From the mid-sixties on, Mostböck turned towards Asian art and philosophy. In 1968, he participated in an exhibition in Dubrovnik together with Japanese and Chinese artists. This was followed by a frequent participation in international exhibitions such as “Art Basel” and “Art Washington”. He showed interest for “Art Brut” and worked on a synthesis of the Asian calligraphy with the European Informel. The 1990s took him back to a reductionist scriptual language of forms. In 2008, Mostböck received a special appreciation of his art, when he was invited to take part in a presentation together with his former role models Jean Fautrier, Emil Schuhmacher, Henri Michaux, Cy Twombly und Mark Tobey in the exhibition “Vom Aufruhr zur Struktur – Schriftwerte im Informel“ which showed examples of German and French informel at the Gustav-Lübcke-Museum in Hamm/Germany.
Karl Mostböck also was an excellent musician (accordion) and passionate jazzman. He was awarded the title “Professor” and the “Austrian Cross of Honor for Arts and Science” and was honorary citizen of both his town of birth, Grein, and his hometown Steyr, where he died on Oct 19, 2013.
