German-born Norwegian printmaker and painter who was one of the first artists to use metal collage in printmaking.

Nesch was educated in Germany at art schools in Stuttgart and Dresden. He was greatly influenced by the Expressionist (Expressionism) painter Ernst Ludwig Kirchner (Kirchner, Ernst Ludwig), under whom he studied in 1924, and also by the Norwegian artist Edvard Munch (Munch, Edvard). About 1925 he began experimenting with unusual printmaking and painting techniques. He fled Germany in 1933 to escape Nazi persecution and settled in Norway, drawn there by his admiration for Munch.

In the 1930s Nesch developed a method of producing deeply embossed graphics by attaching metal strips of soldering wire to the printing plate. This eventually led him to affix metal, wood, coloured glass, and stones to the plate, creating mosaic constructions that were themselves works of art. Nesch's experiments in printmaking helped establish his international reputation; he represented Norway in the Venice Biennale of 1962 and in the São Paulo Biennale of 1973.
