Life
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 Zurich. He received his medical degree from the University of Zürich 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. In 1907, he went to the University of Zurich to study under Otto Haab to be trained as an ophthalmologist and opened his own private practice in Rapperswil SG. In these years, he developed the "Hess screen", married Louise Sandmeier and in 1910 their daughter Gertrud Hess was born. 1913 his son Rudolf Max Hess was born.
In 1912, he left his lucrative private practice as an ophthalmologist and went into research under Justus Gaule (1849 - 1939), habilitating in 1913 to become Privatdozent. His main interests were the regulation of blood flow and respiration. During the First World War he spent a year at the Physiological Institute of the University of Bonn under Max Verworn. In 1916, Gaule retired and Hess first became interim director of the Department of the Physiological Institute at the University of Zürich and in 1917 he was officially promoted to full professor and director of the institute as which he served until retirement 1951.
In the 1930s, he began mapping the parts of the diencephalon that control the internal organs using cats. 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.
Hess retired in 1951 but continued working at the university in an office. In 1967, he moved to Ascona and died of heart failure in 1973 at the age of 92 in Locarno, Switzerland.

Famous quotes containing the word life:
“There is something servile in the habit of seeking after a law which we may obey. We may study the laws of matter at and for our convenience, but a successful life knows no law.”
—Henry David Thoreau (1817–1862)
“The clergyman is expected to be a kind of human Sunday. Things must not be done in him which are venial in the week-day classes. He is paid for this business of leading a stricter life than other people. It is his raison d’être.... This is why the clergyman is so often called a “vicar”Mhe being the person whose vicarious goodness is to stand for that of those entrusted to his charge.”
—Samuel Butler (1835–1902)
“I don’t like your miserable lonely single “front name.” It is so limited, so meagre; it has no versatility; it is weighted down with the sense of responsibility; it is worn threadbare with much use; it is as bad as having only one jacket and one hat; it is like having only one relation, one blood relation, in the world. Never set a child afloat on the flat sea of life with only one sail to catch the wind.”
—D.H. (David Herbert)
