Academic staff of the University of Freiburg

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.

Walter Noddack (17 August 1893 – 7 December 1960) was a German chemist. He, Ida Tacke (who later married Noddack), and Otto Berg reported the discovery of element 43 and element 75 in 1925.

Karl Diehl (March 27, 1864, Frankfurt – May 12, 1943 in Freiburg im Breisgau) was a German economist and professor who taught from 1908 until his death in Freiburg. He taught at the universities of Heidelberg and Freiburg, known for teaching on the subject of Anarchism.The motivating force behind his scholarship was that academia must counter the idea that "...anarchism represents a criminal sect which lacks any social or political programme..." According to one historian on German reformers, Diehl had acquired a reputation as the "most important authority on socialism, communism, and anarchism," comparable only to Werner Sombart.

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.

Hermann Dold (born 5 October 1882 in Stuttgart, died 31 October 1962 in Freiburg im Breisgau) was a German physician and bacteriologist.

Friedrich Wilhelm Daniel Levi (February 6, 1888 – January 1, 1966) was a German mathematician known for his work in abstract algebra, especially torsion-free abelian groups. He also worked in geometry, topology, set theory, and analysis.

Karl Albert Ludwig Aschoff (10 January 1866 – 24 June 1942) was a German physician and pathologist. He is considered to be one of the most influential pathologists of the early 20th century and is regarded as the most important German pathologist after Rudolf Virchow.

Friedrich Meinecke (October 20, 1862 – February 6, 1954) was a German historian, with national liberal and antisemitic views, who supported the Nazi invasion of Poland. After World War II, as a representative of an older tradition, he criticized the Nazi regime, but continued to express antisemitic prejudices.In 1948, he helped to found the Free University of Berlin in West Berlin, and remained an important figure to the end of his life.

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.
