Victor Vasarely was a 20th-century, French-Hungarian artist credited as the father of the Op Art movement. Utilizing geometric shapes and colorful graphics, the artist created compelling illusions of spatial depth. Vasarelyâ€™s method of painting borrowed from a range of influences, including Bauhaus design principles, Wassily Kandinsky, and Constructivism. Vasarely experimented in a style based in Surrealism and Abstract Expressionism during the 1940s before arriving at his hallmark checkerboard works. Op Art went on to have a number of practitioners, including Bridget Riley and Yaacov Agam.
