Chair (II), 1963 (All Photos By Gail)

Günther Uecker (German, b. 1930) is a sculptor, op and installation artist, known for his relief nail works first developed in 1957. His three-dimensional work creates a unique experience as it appears to move and cast different lighting effects as the viewer moves around the work. In 1961, Uecker became a member of the group of artists called ZERO, founded by Heinz Mack and Otto Piene. Inspired by the Kinetic Art movement, the collective grounded their philosophy on theories of light, technology, and optical illusion. Uecker also produces sculptures of pianos and chairs with nails sticking out of them, and he creates sets and costumes for opera performances.
