Jacob Moleschott (9 August 1822 – 20 May 1893) was a Dutch physiologist and writer on dietetics. He is known for his philosophical views in regard to scientific materialism. He was a member of German Academy of Sciences Leopoldina (since 1884).
Viktor Freiherr von Weizsäcker (21 April 1886, in Stuttgart – 9 January 1957, in Heidelberg) was a German physician and physiologist. He was the brother of Ernst von Weizsäcker, and uncle to Richard von Weizsäcker and Carl Friedrich von Weizsäcker. (For his family tree, see Weizsäcker.)
He studied at Tübingen, Freiburg, Berlin, and Heidelberg, where he earned his medical degree in 1910. In 1920, he became head of the neurological department at Ludolf von Krehl's clinic in Heidelberg. In 1941, he succeeded Otfrid Foerster as professor of neurology in Breslau, and in 1945 returned to Heidelberg as a professor of clinical medicine.
Weizsäcker is known for his pioneer work in psychosomatic medicine and for his theories regarding medical anthropology. He is remembered for his concept of Gestaltkreis, an elaboration of Gestalt psychology, in which he explains that biological events are not fixed responses but are dependent upon previous experience and are constantly being repatterned through experience. Via Gestalt, Weizsäcker attempted to theoretically represent the unit of perception and movement.
In the late 1920s, Weizsäcker was co-editor of Die Kreatur with philosopher Martin Buber (1878-1965) and theologian Joseph Wittig (1879-1949). In this journal, Weizsäcker advances his ideas concerning medical anthropology. In 1956, he published Pathosophie, where he tried to create a philosophical understanding of man through his drives, conflicts, and illnesses.
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.
Richard Benedict Goldschmidt (April 12, 1878 – April 24, 1958) was a German geneticist. He is considered the first to attempt to integrate genetics, development, and evolution. He pioneered understanding of reaction norms, genetic assimilation, dynamical genetics, sex determination, and heterochrony. Controversially, Goldschmidt advanced a model of macroevolution through macromutations popularly known as the "Hopeful Monster" hypothesis.Goldschmidt also described the nervous system of the nematode, a piece of work that influenced Sydney Brenner to study the "wiring diagram" of Caenorhabditis elegans, winning Brenner and his colleagues the Nobel Prize in 2002.
Otto Frank (21 June 1865 – 12 November 1944) was a Grand Duchy of Hesse born medical doctor and physiologist who made contributions to cardiac physiology and cardiology. The Frank–Starling law of the heart is named after him and Ernest Starling.
Wilhelm Kolle (born 2 November 1868 in Lerbach near Osterode am Harz, died 10 May 1935) was a German bacteriologist and hygienist. He served as the second director of the Royal Institute for Experimental Therapy, succeeding its founder, the Nobel laureate Paul Ehrlich. He was also the original author, with Heinrich Hetsch, of the famous book Experimental Bacteriology, one of the most authoritative works in microbiology in the first half of the 20th century.
Following studies of medicine at the universities of Göttingen, Halle and Würzburg, he became an assistant to Robert Koch at the Institut für Infektionskrankheiten (Institute for Infectious Diseases) in Berlin (1893–97). In 1897–98 he performed research of rinderpest and leprosy in South Africa, and in 1900, on behalf of the Egyptian government, studied rinderpest in Sudan.
In 1901 he became departmental head at the Institut für Infektionskrankheiten, followed by an appointment as professor of hygiene and bacteriology at the University of Bern (1906). As a military physician and hygienist during World War I, he was highly successful in vaccination against diphtheria and cholera. In 1917, he became director of the Royal Institute for Experimental Therapy and of the Georg Speyer House in Frankfurt am Main.
Kolle made numerous contributions in the fields of serology, microbiology and chemotherapy. He is credited with the development of an anti-meningococcus serum, as well as a vaccine against rinderpest. He introduced an improved Salvarsan preparation for treatment of syphilis, and in 1896 developed a heat-inactivated cholera vaccine that was used extensively during the 20th century.He was the father of the painter Helmut Kolle (1899–1931).
Paul Emil Flechsig (29 June 1847, Zwickau, Kingdom of Saxony – 22 July 1929, Leipzig) was a German neuroanatomist, psychiatrist and neuropathologist. He is mainly remembered today for his research of myelinogenesis.
Friedrich Carl Duisberg (29 September 1861 – 19 March 1935) was a German chemist and industrialist.
Oskar Franz Xaver Miller, since 1875 von Miller (7 May 1855 – 9 April 1934), was a German engineer and founder of the Deutsches Museum, a large museum of technology and science in Munich.
Gustav Nachtigal (German: [ˈɡʊstaf ˈnaxtɪɡal]; born 23 February 1834 – 20 April 1885) was a German military surgeon and explorer of Central and West Africa. He is further known as the German Empire's consul-general for Tunisia and Commissioner for West Africa. His mission as commissioner resulted in Togoland and Kamerun becoming the first colonies of a German colonial empire. The Gustav-Nachtigal-Medal, awarded by the Berlin Geographical Society, is named after him.
