Nikolai Kasak (1917–1994) . An artist of Belarusian descent, Kasak began his formal training in the 1930’s in Warsaw, continuing on to Vienna, then Rome. He was originally trained in the academic style of late nineteenth century Realism, until the artist encountered abstract art for the first time in 1945. The artists of De Stijl, Russian Constructivism, and Suprematism had vast influence on Kasak, prompting him to shift his focus from a primarily figure-based aesthetic to pure abstraction. Concentration of form, formulaic compositions, and solid color shapes became the significant structural element in his painting. Upon immigrating to the United States post- World War II, Kasak had the opportunity to exchange creative ideas with other Eastern- European and Russian émigré circles, formulating and fine-tuning his artistic ideology.
Kasak also became involved with the Madi movement of Argentina through Gyula Kosice. It was Piero Dorazio who first sent an image of Kasak’s work to be included in the Madi Magazine. Kosice formally invited Kasak in a letter dated January 25, 1950, to be part of the Madi Movement. After acceptance by Kasak , he showed his work in multiples occasion as part of the Madi Group, worth to mention International Madi Art, Galeria Bonino Buenos Aires, 1957, International Madi, Galerie Denise Rene , Paris 1960 and 15 years of Madi Art, Modern Art Museum of Buenos Aires in 1961.
