Fritz Winter was a German abstract painter and sculptor whose geometric compositions emerged from constructivist principles and his experience of postwar reconstruction. Working primarily in oil and mixed media, he developed a vocabulary of interlocking planes and bold primary colors that conveyed movement and spatial tension without representational reference. Winter's work bridges early modernism and the postwar European abstraction that dominated the 1950s and 1960s.
