Julian Stanczak was a Polish-born American painter and printmaker who is considered a central figure of the Op art movement in the U.S. during the 1960s and 1970s. Described as an artist whose work "evinced a tremendous geometric inventiveness", Stanczak is primarily known for his large-scale polychromatic abstract compositions made using acrylic paint on canvas in which he explored the perceptual dimensions of color.
