Peter Wyss was born in 1943 in Zürich. He studied scientific drawing with Karl Schmid at the Kunstgewerbeschule Zürich. After two years working in pharmaceutical advertising at Geigy in Basel he moved to Paris. There he enjoyed a successful career as a freelance illustrator for various international magazines and advertisement agencies. His calligraphic creations were in demand and drew clients such as Credit Suisse, Beyer, and Blondino.
