Nesch was born in Esslingen am Neckar, and studied at the academy in Dresden from 1912 to 1914. He then participated in World War I, but was taken prisoner by the British. In 1929 he settled in Hamburg to continue his painting career, influenced by expressionism in general, especially Ernst Ludwig Kirchner and Edvard Munch.
Nesch died in 1975 in Oslo. The Nesch Museum opened in 1993 in Ål, where he had lived for twenty-five years, to commemorate his hundredth anniversary.Wikipedia
