Born in 1937 in Falkenstein, Lower Austria, as the son of a head forester, Korab already harboured the desire to become an artist during his school years; painting and drawing were his outlet. His preferred subjects were landscapes, still lifes and portraits.
From 1957 to 1964, Korab studied at the Academy of Fine Arts in Vienna under Sergius Pauser and Herbert Boeckl. During his training he met representatives of the Viennese School of Fantastic Realism (Ernst Fuchs and Anton Lemden) and temporarily adopted their style of painting in the style of the Old Masters.
From the mid-1960s, however, he developed his own style of painting - far removed from illusions. His depictions of people became increasingly abstract and, over time, were replaced by masks. Korab expanded his artistic repertoire to include depictions of cities and machines. In parallel, the artist now concentrated on printmaking, especially screen printing. From 1980 onwards, the theme of landscape became increasingly important for the artist. In addition, he discovered collage on various materials for himself; on paper on the one hand, and on ash, sand, wood, metal and canvas on the other. Some time later, Korab went on long journeys across Europe with his second wife. In Ireland, he produced a book of drawings and photographs, which became a great success.
Korab has already received many awards for his artistic work, including the Great Decoration of Honour for Services to the Province of Lower Austria in 2012. Today, his paintings can be found in numerous collections, both in Austria and abroad.
