In 1947 Bertschmann began four years of study at the Basel School of Design (Kunstgewerbeschule) under a staff of well-known art instructors. Of particular importance and influence was the graphic design department, led by Armin Hofmann [b.1920] whose collaborating instructor was the great typographer Emil Ruder [1914-1970]. They were reinforced by Donald Brun [1909-1999], another of the world’s most famous poster designers. Hofmann, who later taught at Yale, is credited for having developed the Swiss Style in graphic design — noted for its dynamic compositions,.
