In the post war period the gallerist György Koller (1923–1996) founded the Association of Hungarian Engravers (“RMAK”)in 1953. In 1980, the first private gallery of Hungary was opened in the atelier-house of the Hungarian-Italian sculptor Amerigo Tot. From that time on the Koller Gallery presented not only graphic artists, but also sculptures and paintings. By 1984, an exhibition cum auction room was established in the Hungarian National Gallery, which is known to extend cooperation with Koller Gallery. Additionally, an exhibition room was opened in Sándor Petőfi street as well as in the Hilton Hotel in the Castle District. György Koller died in 1996.
