Marian Bogusz spent part of World War II as a prisoner of the concentration camp at Mauthausen. This experience did not, however, directly influence his later life. Perhaps this enabled him after 1945 to become one of the most important figures in the Polish arts, both as an independent artist and as someone who spawned many important community and national projects which, although varied, were primarily avant-garde in nature. Bogusz received his training as a painter between 1946 and 1948 at Warsaw's Academy of Fine Arts where he studied under Jan Cybis and Jan Sokołowski among others. In 1947 he began to work actively with the Warsaw-based Young Artists and Scientists Club, which was an unusually lively source of intellectual and artistic initiatives whose impact was felt throughout the country. During the Socialist Realist period he withdrew into the background, as did many artists, limiting himself to designing scenery and exhibitions.
