The Zuntz-Geppert respiratory apparatus, created in 1885, became a foundational instrument for measuring metabolic processes during physiological research. Developed by Nathan Zuntz alongside August Julius Geppert, this device exemplified the career of a man who transitioned from medical training at the University of Bonn to become a significant force in altitude physiology and aviation medicine in Germany.
Early Career and Academic Appointments
Born in Bonn in 1847, Zuntz undertook his medical education at the University of Bonn, where he earned a Doctor of Sciences degree. He began his professional path as an assistant to Max Schultze in 1868. Following a period of research in Berlin, he returned to Bonn in 1870 to assist the physiologist Eduard Pflüger. By 1872, he held an honorary professorship of physiology at the Landwirtschaftliche Akademie in Poppelsdorf. His academic tenure culminated in a professorship at the Landwirtschaftliche Hochschule Berlin, a position he maintained from 1881 until his retirement in 1919.

Zuntz focused on the practical application of physiology, particularly regarding respiration, nutrition, and metabolism. To conduct precise field studies, he invented a portable dry gas measuring device known as a Gasuhr. In 1889, he engineered an early treadmill, which he later upgraded in 1914 by integrating an X-ray apparatus to monitor cardiac activity during physical exertion. His commitment to practical science further manifested in 1911 when he established the first laboratory in Germany dedicated exclusively to the study of sports medicine.
High-Altitude and Aviation Research
Extensive investigation into extreme conditions formed a significant portion of his research, often conducted at the Capanna Regina Margherita station on Monte Rosa. In 1902, Zuntz completed two balloon ascents reaching 5000 meters in partnership with Hermann von Schrötter, Arthur Berson, and Reinhard Süring. His subsequent 1910 expedition to the Pico de Teide in the Canary Islands, conducted with Schrötter, Arnold Durig, and Joseph Barcroft, expanded his findings. These inquiries informed his 1906 book, "Höhenklima und Bergwanderungen in ihrer Wirkung auf den Menschen," and his 1912 publication on the physiology and hygiene of aviation.
Professional Honors and Affiliations
Throughout his career, Zuntz maintained formal connections with prestigious scientific bodies. He was elected a member of the German Academy of Sciences Leopoldina in 1884 and later joined the Hungarian Academy of Sciences. The academic community recognized his contributions through several honors, including the Order of the Red Eagle 4th Class, the Order of Saint Stanislaus 2nd Class, and an honorary doctorate awarded by the University of Natural Resources and Life Sciences in Vienna in 1913. He died in Berlin in 1920.
