Günther Uecker is a German artist. He occupied himself with the medium of light, studied optical phenomena, series of structures and the realms of oscillation which actively integrate the viewer and enable him to influence the visual process by kinetic or manual interference. Uecker, Mack and Piene began working together in joint studios at the Stedelijk Museum in Amsterdam in 1962 and installed a 'Salon de Lumière' at the Palais des Beaux-Arts in Paris. Other 'light salons' followed in Krefeld and in Frankfurt. Since 1966, after the group ZERO dissolved and a last joint exhibition, Uecker increasingly used nails as an artistic means of expression - a material which, until today, stands in the centre of his oeuvre. At the beginning of the 1960s he began hammering nails into pieces of furniture, musical instruments and household objects, then he began combining nails with the theme of light, creating his series of light nails and kinetic nails and other works. Light and electricity continued to be one of the main subjects and natural materials such as sand and water were included in his installations, resulting in an interaction of the different elements to create a sensation of light, space, movement and time. Günther Uecker's oeuvre includes painting, object art, installations as well as stage designs and films.
Uecker taught from 1974 until 1995 at the Kunstakademie Düsseldorf and was promoted to professor in 1976. With Otto Piene, Heinz Mack and Mattijs Visser he founded in 2008 the international ZERO foundation. The foundation has the complet ZERO archives from three Düsseldorfer artists as well as documents and photos from other related artist.
