Academic staff of Goethe University Frankfurt

Alexander Ellinger (17 April 1870 in Frankfurt am Main – 26 July 1923 in Frankfurt am Main) was a German chemist and pharmacologist.
From 1887 he studied chemistry at the University of Berlin under August Wilhelm von Hofmann and at the University of Bonn as a pupil of August Kekulé. Afterwards, he studied medicine at the University of Munich, followed by work as an assistant in the institute of pharmacology at the University of Strasbourg. In 1897 he became an assistant to Max Jaffé in the laboratory of medicinal chemistry and experimental pharmacology at the University of Königsberg. In 1914 he was appointed professor of pharmacology at the newly established University of Frankfurt.He is remembered for his extensive biochemical research of several amino acids, especially tryptophan. In 1904 he isolated kynurenic acid from the urine of dogs that had been fed tryptophan. His other work included studies on the water exchange between body tissues and blood, on the formation on lymph, and with chemist Karl Spiro, he conducted investigations of blood coagulation.

Ludwig Edinger (13 April 1855 – 26 January 1918) was an influential German anatomist and neurologist and co-founder of the University of Frankfurt. In 1914 he was also appointed the first German professor of neurology.
Edinger was born into a Jewish family and grew up in Worms, where his father was a successful textile salesman and democratic congressman in the state parliament of Hesse-Darmstadt. His mother was the daughter of a physician from Karlsruhe. He was not ashamed that he started his career as a poor man. Indeed, he proposed free schooling for all children in 1873, but without success.
Edinger studied medicine from 1872 to 1877 in Heidelberg and Strasbourg. His studies into neurology began during his time as an assistant physician in Giessen (1877 - 1882). His habilitation was in 1881 about neurological researches. He became a docent for these themes. He worked in Berlin, Leipzig and Paris and opened his own practice for neurology in Frankfurt am Main in 1883.
Due to Edingers initiative in 1885, the pathologist Karl Weigert became director of the Dr. Senckenbergische Anatomie in Frankfurt. Weigert opposed antisemitism. Weigert gave his friend Edinger a place to work in his institute. In 1902, Edinger received enough space to start his own neurological department.
In 1909, after a dispute between Edinger and the Senckenberg foundation about the finances of the neurological institute, Edinger moved to the University of Frankfurt under the condition that he was responsible for the financing of the department. His problems had eased in 1886, when he married Anna Goldschmidt, the daughter of an old family of traditional Jewish bankers in Frankfurt; she received a large inheritance in 1906.
Edinger died suddenly on 26 January 1918 in Frankfurt of a heart attack. He had left instructions for his brain to be examined in his institute. The institute continued with the introduction of a foundation set-up by Edinger. The Neurology department of the Goethe University's Faculty of Medicine is named after him.
Edinger is credited with coining the terms "gnosis" and "praxis". These terms were later used in psychological descriptions of agnosia and apraxia. Also, he was the first to describe the ventral and dorsal spinocerebellar tracts and to distinguish the paleocerebellum from the neocerebellum.

Ludwig Georg Elias Moses Bieberbach (German: [ˈbiːbɐˌbaχ]; 4 December 1886 – 1 September 1982) was a German mathematician and Nazi.

Walter Emmerich Behrmann (May 22, 1882, Oldenburg – May 3, 1955, Berlin) was a German geographer. He is remembered for introducing a cylindrical map projection known as the "Behrmann projection".

Walther Gerlach (1 August 1889 – 10 August 1979) was a German physicist who co-discovered, through laboratory experiment, spin quantization in a magnetic field, the Stern–Gerlach effect. The experiment was conceived by Otto Stern in 1921 and successfully conducted first by Gerlach in early 1922.
