Erwin Hauer (January 18, 1926, Vienna, Austria - December 22, 2017, Branford, Connecticut) was an Austrian-born American sculptor who studied first at Vienna's Academy of Applied Arts and later under Josef Albers at Yale. Hauer was an early proponent of modular constructivism and an associate of Norman Carlberg. Like Carlberg, he was especially known for his minimalist, repetitive pieces in the 1950s and 1960s. Hauer's design studio in New Haven, Connecticut is well known for the production of sculptural, light-diffusing architectural screens and walls employing Hauer's modular style.
