The news of his passing on August 14 was announced by the Stefan Gierowski Foundation on social media late on Wednesday.
Gierowski was regarded as one of the most prominent representatives of Polish abstract art.
In the early stages of his career, after graduating from the Fine Arts Academy in the southern city of Kraków, he explored the figurative trend and remained under the influence of cubism.
Having entered the abstract path in 1957, he never gave titles to his works, merely providing them with Roman numerals.
From the 1990s onward, Gierowski employed ever bolder colours in his paintings.
One of his major works from that period is the Painting the Ten Commandments series, inspired by a 15th-century Tablet of Ten Commandments.
Gierowski was also a professor at the Fine Arts Academy in Warsaw for several decades. In 1983, he was elected its Rector, but the communist authorities rejected his candidature because of his close contacts with independent culture groups.
Gierowski’s works are held in numerous private and public collections, including the National Museums in Warsaw, Kraków, Poznań, Wrocław and Gdańsk, as well as the Art Museum in Łódź, the Zachęta Gallery in Warsaw and the Centre for Contemporary Art in Warsaw.
