Josef Albers was not just an artist but a theoretician and teacher. “In math and science, one plus one is two,” he said. “In art, one plus one is two and also much more.” Born in Bottrop, Germany, in 1888, he studied and taught at the Bauhaus, then immigrated to North Carolina where he joined the faculty of Black Mountain College and ran its art department (Ruth Asawa and Robert Rauschenberg were among his students). In 1950, Albers launched his innovative “Homage to the Square” series, which explored how color interacted with geometric form. Albers was fascinated with duality. Juxtaposing different forms, he claimed, offered the viewer a visual feast. David Zwirner LA re-creates and expands on this notion, placing works from the 1930s through the 1970s in pairs. —Maggie Turner
