University of Freiburg alumni

Sir Hans Adolf Krebs, FRS (, German: [hans ˈʔaːdɔlf ˈkʁeːps] ; 25 August 1900 – 22 November 1981) was a German-British biologist, physician and biochemist. He was a pioneer scientist in the study of cellular respiration, a biochemical process in living cells that extracts energy from food and oxygen and makes it available to drive the processes of life. He is best known for his discoveries of two important sequences of chemical reactions that take place in the cells of nearly all organisms, including humans, other than anaerobic microorganisms, namely the citric acid cycle and the urea cycle. The former, often eponymously known as the "Krebs cycle", is the sequence of metabolic reactions that allows cells of oxygen-respiring organisms to obtain far more ATP from the food they consume than anaerobic processes such as glycolysis can supply; and its discovery earned Krebs a Nobel Prize in Physiology or Medicine in 1953. With Hans Kornberg, he also discovered the glyoxylate cycle, a slight variation of the citric acid cycle found in plants, bacteria, protists, and fungi.
Krebs died in 1981 in Oxford, where he had spent 13 years of his career from 1954 until his retirement in 1967 at the University of Oxford.

Stephan Kurt Westmann (23 July 1893 – 7 October 1964) was a German soldier and physician.
In the First World War, Westmann served in the German 29th Infantry Division on the Western and Eastern fronts and then as an Air Force surgeon, although unqualified. He volunteered to serve in the Reichswehr after the war. After he was discharged, he completed his medical studies and became a professor at the University of Berlin, and in the 1930s migrated to England and became a doctor in Harley Street, Westminster. During the Second World War, he was a British medical officer in Scotland, so that in the two World Wars he served on different sides.
In later life, Westmann appeared on BBC television to talk about the First World War from the German point of view and also wrote his memoirs.

Selmar Aschheim (4 October 1878 – 15 February 1965) was a German gynecologist who was a native resident of Berlin.
Born into a Jewish family, in 1902 he received a doctorate of medicine in Freiburg, and later became director of the laboratory of the Universitäts-Frauenklinik at the Berlin Charité. In 1930 Aschheim attained the chair of biological research in gynecology at the University of Berlin. In 1933 he fled Nazi Germany and moved to Paris, where he worked in medical research at the Hôpital Beaujon.
Aschheim was a specialist concerning gynecological histology and hormone research. In 1928 with endocrinologist Bernhard Zondek (1891–1966), he isolated the gonadotropic hormone known as human chorionic gonadotropin (hCG), which was discovered in the urine of pregnant women. From their research the "Aschheim-Zondek test" for pregnancy was created, which involved injection of a patient's urine into an immature laboratory mouse. If the rodent displayed an estrous reaction, it represented a positive indication of pregnancy.
The two doctors published the findings of the hormone in a treatise titled Das Hormon des Hypophysenvorderlappens. At the time they believed that the gonadotrophin was produced by the anterior pituitary, however further research in the 1940s demonstrated that the placenta was responsible for the elaboration of the hormone.

Hillel Oppenheimer (Hebrew: הלל אופנהיימר, born Heinz Reinhard Oppenheimer; 4 April 1899 – 15 June 1971), was an Israeli professor of botany.

Norbert Elias (German: [ˈnɔʁbɛʁt ʔeˈliːas]; 22 June 1897 – 1 August 1990) was a German sociologist who later became a British citizen. He is especially famous for his theory of civilizing/decivilizing processes.

Paul Trendelenburg (24 March 1884, Bonn – 4 February 1931, Berlin) was a German pharmacologist.
He studied medicine at the universities of Grenoble, Leipzig and Freiburg, where from 1909 to 1918, he worked as an assistant in the pharmacological institute and at the surgical clinic. In 1912 he received his habilitation in pharmacology and toxicology, and from 1916 was an associate professor. In 1919 he became a full professor at the University of Rostock and later on, he served as a professor of pharmacology at the universities of Freiburg (from 1923) and Berlin (from 1927).He is known for his research of adrenaline, for the development of biological measurement procedures for the standardization of hormone preparations and for his investigations regarding the role of the hypothalamic hormones vasopressin and oxytocin. His name is associated with the so-called "Trendelenburg preparation", a preparation used in determining the actions of pharmacological agents on peristalsis.He was the son of surgeon Friedrich Trendelenburg and the brother of physiologist Wilhelm Trendelenburg. His son, Ullrich Georg Trendelenburg, was also a pharmacologist.

Edgar Goldschmid (born 14 December 1881 in Frankfurt, died 26 May 1957 in Lausanne) was a German physician, pathologist and historian of medicine.

Hans Adolf Eduard Driesch (28 October 1867 – 17 April 1941) was a German biologist and philosopher from Bad Kreuznach. He is most noted for his early experimental work in embryology and for his neo-vitalist philosophy of entelechy. He has also been credited with performing the first artificial 'cloning' of an animal in the 1880s, although this claim is dependent on how one defines cloning.

Hans Bender (5 February 1907 – 7 May 1991) was a German lecturer on the subject of parapsychology, who was also responsible for establishing the parapsychological institute Institut für Grenzgebiete der Psychologie und Psychohygiene in Freiburg. For many years his pipe smoking, contemplative figure was synonymous with German parapsychology. He was an investigator of 'unusual human experience', e.g. poltergeists and clairvoyants. One of his most famous cases was the Rosenheim Poltergeist.
