From around 1958, Leo Erb started with his structured 'line paintings' and 'line reliefs', with which he exhibited, among other things, in Düsseldorf in 1958 as part of the 7th evening exhibition “Das Rote Bild” of the ZERO group in Düsseldorf.
In 1961 Erb moved to Paris, where he lived and worked in his self-built studio until 1975. During this period he further developed his line works and created “linear light objects”, “solar sculptures” and kinetic objects. In 1977 he took part in Documenta 6 in Kassel. 'The line' and the color white in all its shades run like a common thread through Leo Erb's entire work. This core theme affects all his working groups, such as signatures, material images, reliefs, sculptures, kinetic objects, light objects and handprints.
In Erb's work “… the great Bauhaus doctrine returns, radicalized and concentrated on the essential elements. Many of Erb's line paintings and line objects are both flat and spatially legible. Erb's lines are three-dimensional edges of light or shadow; They turn images into things that present themselves to the light, that live in the light” (Lorenz Dittmann).
