Ryszard Winiarski (1936, Lviv - 2006, Warsaw), a Polish painter, stage designer and author of spatial forms. A Professor at the Academy of Fine Arts in Warsaw. A winner of Jan Cybis Award (1996). He was one of the major representatives of indeterminism in art. He held both a Master of Science degree as well as a degree in the Master of Arts.
Winiarski's art practice is based on mathematics and science. In his opinion, it was possible to build bridges between life, science, technology and art." He did not create "images" but "areas," which came into being through increasingly more complicated functions of random variables. At the same time the selected method allowed the artist to diversify techniques: he made three-dimensional, relief, kinetic, colourful objects. A project of arranging the interior of an individual exhibition in Zachęta National Gallery of Art as a monumental, prostrate image was a large-scale experiment (1970).
Polish art critic and historian Mieczysław Porębski wrote in the introduction to the catalogue for the first individual exhibition of Winiarski (Contemporary Gallery, Warsaw, 1967) as follows: "There is also the language of mathematics. If I try to learn it, I do not do it because of snobbery or pedantry. Simply it seems to me that – at our age – it is not possible to express certain matters which I find interesting and care for in a different language. Not merely express. More: see. I cannot agree that there is such a language and that I would be forced to capitulate before it in advance. If engineers, biologists, economics can use it – it is not right that philosophers, linguists, art critics, artists cannot make expressions in it".
