Nathan Zuntz

Nathan Zuntz (6 October 1847, Bonn – 22 March 1920, Berlin) was a German physiologist born in Bonn. He was a pioneer of modern altitude physiology and aviation medicine.

He studied medicine at the University of Bonn, where he was an assistant to Max Schultze. In 1868 he earned his doctorate, and following a study trip to Berlin, returned to Bonn in 1870 as an assistant to physiologist Eduard Pflüger. The following year he became a lecturer at the University of Bonn, and in 1872 was an honorary professor of physiology at the Landwirtschaftlichen Akademie at Poppelsdorf. From 1881 until his retirement in 1919, he was a professor at the Landwirtschaftliche Hochschule Berlin (Royal Agricultural College) in Berlin.

Zuntz was involved in many facets of physiological research, including metabolism, respiration and nutrition, and is well known for his work in high-altitude physiology. He conducted extensive research on the physiological changes in animals and humans in extreme conditions. Many of his field studies were conducted at Capanna Regina Margherita, a research station at the apex of Monte Rosa, Italy. In 1902 with his assistant Hermann von Schrötter and meteorologists Arthur Berson and Reinhard Süring, he made two high-altitude balloon ascents in which they reached an altitude of 5000 meters. In 1910 Zuntz participated in a scientific expedition to Pico de Teide in the Canary Islands with Schrötter and physiologists Arnold Durig (1872-1961) and Joseph Barcroft (1872-1947).
