Walter Rudolf Hess

Walter Rudolf Hess (17 March 1881 – 12 August 1973) was a Swiss physiologist who won the Nobel Prize in Physiology or Medicine in 1949 for mapping the areas of the brain involved in the control of internal organs. He shared the prize with Egas Moniz.

Early life and education Hess was born in Frauenfeld as the second of three children to Clemens Hess and Gertrud Hess (née Fischer). His father encouraged him to pursue a scientific career and with him he conducted experiments in his physics laboratory. He started to study medicine in Lausanne in 1899 and then in Berlin, Kiel and Zürich. He received his medical degree from the University of Zurich in 1906 and trained as surgeon in Münsterlingen (in the same canton as his birthplace Frauenfeld) under Conrad Brunner (1859–1927). He developed a viscosimeter to measure blood viscosity and published his dissertation in 1906 titled Zum Thema Viskosität des Blutes und Herzarbeit. This research won him the Nobel prize in Physiology and Medicine 1949. Hess also helped to found the meteorological research foundation International Foundation for the High Alpine Research Station Jungfraujoch in 1930 and served as its director until 1937. Furthermore, he politically campaigned against the anti-vivisectionists that wanted to forbid animal experimentation.
