Anton Hermann Victor Thomas Schrötter, name sometimes referred to as Hermann Schrötter von Kristelli (5 August 1870 – 6 January 1928) was an Austrian physiologist and physician who was a native of Vienna. He was the son of laryngologist Leopold von Schrötter (1837–1908), and grandson to chemist Anton Schrötter von Kristelli (1802–1875).
He studied medicine and natural sciences at the Universities of Vienna and Strasbourg, earning his medical degree in 1894, and during the following year receiving his doctorate of philosophy. Afterwards he worked under Carl Gussenbauer (1842–1903) at the University Hospital in Vienna and was an assistant to his father at the clinic of internal medicine. In the mid-1890s with physiologist Nathan Zuntz (1847–1920) and others, he began investigations involving physiological effects on the body associated with air pressure and altitude change. In 1896 made the first in a series of several high-altitude balloon ascents.
In 1910 Schrötter accompanied scientists Nathan Zuntz, Arnold Durig (1872–1961) and Joseph Barcroft (1872–1947) on an expedition to Tenerife, where he conducted research involving respiration and oxygenation at higher elevations. During the Balkan Wars of 1912-13, he worked with the Red Cross in Montenegro, afterwards serving as a physician during World War I (including a stint as Sanitätschef in Jerusalem). After the war he was director of Malariaspitals in Wieselburg, and following his discharge from military service, he was in charge of the Alland Lungenheilanstalt (lung hospital founded by his father in 1898). In the 1920s he made balneological studies of the Dead Sea, and in 1925 was habilitated for internal medicine at the University of Vienna.
