Klaus Hepp

Klaus Hepp (born 11 December 1936) is a German-born Swiss theoretical physicist working mainly in quantum field theory.Hepp studied mathematics and physics at Westfälischen Wilhelms-Universität in Münster and at the Eidgenössischen Technischen Hochschule (ETH) in Zurich, where, in 1962, with Res Jost as thesis first advisor and Markus Fierz as thesis second advisor, he received a doctorate for the thesis ("Kovariante analytische Funktionen“) and at ETH in 1963 attained the rank of Privatdozent.Hepp was also Loeb Lecturer at Harvard and was at the IHÉS near Paris.[1] In quantum field theory he gave a complete proof of the Bogoliubov–Parasyuk renormalization theorem (Hepp and Wolfhart Zimmermann, called in their honor the BPHZ theorem).[2] Since a research stay 1975/6 at MIT he also worked in neuroscience (for example, reciprocal effect between movement sensors, visual sense and eye movements with V. Henn in Zurich).
