Peter Somm was born in Sulgen (Thurgau) in 1940. After leaving school he studied medicine in Freiburg, then Zurich. During this time he explored art and took courses in painting and drawing, but he is largely self-taught. Since the mid-1960s he has focused on the constructivist style. He held his first group exhibition in 1968. In 1972 he moved to Herrenschwanden near Bern, and worked part-time as an anaesthetist until 1999. He immerses himself in art and is developing his work further. He lives and works in Herrenschwanden.
