Born in 1930 at Basle. Gerstner died in 2017.
One of the most important Swiss artists representing Concrete Art. His book »Kalte Kunst« (Cold Art), released in 1957, has been understood as being programmatic for Concrete Art and reveals his fascination for mathematical theories. In his pictures Gerstner concentrates on delicate chromatic gradation. In 1964 Gerstner and Spoerri were the editors of the famous »MAT edition«.
