Brazilian artist Almir da Silva Mavignier has pursued geometric abstraction, Op art, and graphic design. After studying with the Hungarian-born painter Árpád Szenès (1897–1985) in 1946, Mavignier created his first abstract paintings in 1949. After his work was featured in a solo exhibition at the Museum of Modern Art, São Paulo, in 1951, he devoted himself to Concrete art. From 1953 to 1958 Mavignier studied at the Hochschule für Gestaltung College of Design) in Ulm, Germany, with Josef Albers, Max Bense, and Max Bill. In 1954 he created his breakthrough color-point grid series that causes optical vibrations. While living in Paris in 1958, Mavignier joined the radical ZERO group, whose artists rejected color and expression for ephemeral events and nontraditional materials. In 1961 he co-organized Nove Tendencije (New Tendencies), the first Yugoslavian exhibition devoted to post-informel art, with the art historian Marko Mestrovich and Bozo Bek, director of the Museum of Contemporary Art, Zagreb. Mavignier’s work was included in the Venice Biennale (1964), Documenta (1964; 1968), and the kinetic and Op art exhibition The Responsive Eye at the Museum of Modern Art, New York (1965). He taught at the Hochschule für Bildende Künste (College of Fine Arts) in Hamburg from 1965 to 1990.
