Werner Heinrich Gustav Kolhörster (28 December 1887 – 5 August 1946) was a German physicist and a pioneer of research into cosmic rays.
Kolhörster was born in Schwiebus (Świebodzin), Brandenburg Province of Prussia. While attending the University of Halle, he studied physics under Friedrich Ernst Dorn.Repeating the cosmic ray experiments of Victor Hess, in 1913-14 Kolhörster ascended by balloon to an altitude of 9 km, where he confirmed Hess' result that the ionization rate from cosmic rays was greater at that altitude than at sea level. This was evidence that the source for these ionizing rays came from above the Earth's atmosphere.Kolhörster continued his physics studies at the Physikalisch-Technische Reichsanstalt in Berlin, beginning in 1914. During World War I he made measurements of atmospheric electricity in Turkey. Following the war he became a teacher. He joined the Physikalisch-Technische Reichsanstalt in 1922.In 1928–29, Walter Bothe and Kolhörster used the Geiger-Muller detector to demonstrate that cosmic rays were actually charged particles. The ability of these particles to penetrate the Earth's atmosphere meant that they must be highly energetic.In 1930, Kolhörster started the first institute for the study of cosmic rays in Potsdam, with financial assistance from the Prussian Academy of Sciences. He became director of the Institut für Hohenstrahlungsforschung in Berlin-Dahlem in 1935, where he was appointed an ordinary professor.Kolhörster was killed in a car crash in Munich. The crater Kolhörster on the Moon is named in his memory.

Eduard von Martens (18 April 1831 – 14 August 1904) also known as Carl or Karl Eduard von Martens, was a German zoologist.Born in Stuttgart in 1831, von Martens attended university in Tübingen, where he graduated in 1855. He then moved to Berlin, where he would be based for the remainder of his career, both at the Zoological Museum of the Berlin University (from 1855) and, from 1859 on, at the Museum für Naturkunde.In 1860, he embarked on the Thetis expedition of the Prussian expedition to Eastern Asia. When the expedition returned to Europe in 1862, von Martens continued to travel around Maritime Southeast Asia for 15 months. He published the results of the "Thetis" expedition in two volumes, constituting the Zoologischer Theil of the "Preussische Expedition nach Ost-Asien." Vol. ii, consisting of 447 pages and 22 plates, contained a very full account of the land molluscs.
Back in Berlin, von Martens was curator of the malacological and other invertebrate sections until his death.Von Martens described 155 new genera (150 of them molluscs) and almost 1,800 species (including around 1,680 molluscs, 39 crustaceans, and 50 echinoderms).
He was a foreign member of the Linnean Society of London, and a corresponding member of the Zoological Society of London.

Hermann Johannes Karl Fehling (14 July 1847 - 11 November 1925) was a German obstetrician and gynecologist who was a native of Stuttgart. He was the son of the chemist Hermann von Fehling (1811-1885).
In 1872 he received his medical doctorate from the University of Leipzig, and following graduation remained in Leipzig as an assistant to obstetrician Carl Siegmund Franz Credé (1819-1892). In 1877 he became director of the Württemberg state midwifery school in Stuttgart, and later accepted a teaching job at the University of Tübingen (1883).
In 1887 he became a professor of obstetrics at the University of Basel, and afterwards served as a professor at the Universities of Halle (1894) and Strasbourg (1900). In the aftermath of World War I, Fehling along with other German professors were expelled from the University of Strasbourg. He eventually settled in Baden-Baden, where he died in 1925.
Hermann Fehling is considered to be one of the leading gynecologists of his era, and made contributions in his research of disorders that included eclampsia, rachitic pelvis and puerperal osteomalacia. In 1877, with Heinrich Fritsch (1844-1915), he founded the journal Zentralblatt für Gynäkologie.

Eugen Baumann (12 December 1846 – 3 November 1896) was a German chemist. He was one of the first people to create polyvinyl chloride (PVC), and, together with Carl Schotten, he discovered the Schotten-Baumann reaction.

Christian Gottlieb Ferdinand Ritter von Hochstetter (30 April 1829 – 18 July 1884) was a German-Austrian geologist.

Fritz Georg Arndt (6 July 1885 – 8 December 1969) was a German chemist recognised for his contributions to synthetic methodology, who together with Bernd Eistert discovered the Arndt-Eistert synthesis.

Rudolf Magnus (2 September 1873, Brunswick – 25 July 1927, Pontresina) was a German pharmacologist and physiologist. He studied medicine, specialising in pharmacology, in Heidelberg, where he became associate professor of pharmacology in 1904. In 1908 he became the first professor of pharmacology in Utrecht, where he spent the rest of his working life.
Had he lived, he likely would have been awarded the Nobel Prize for his work on animal reflexes. The authors of Nobel, the Man and his Prizes by H.Schück et al., edited by the Nobel Foundation (2nd ed. Amsterdam, 1962, p. 311) wrote of Magnus and his co-worker De Kleyn: ‘The examiner [1927] declared that the work done by Magnus and De Kleyn clearly deserved a prize, and the prospects for an award seemed most favourable when Magnus unexpectedly died.’ For his life and work see, Rudolf Magnus, Physiologist and Pharmacologist: A Biography (2002, Royal Netherlands Academy of Arts and Sciences) by his son, Dr.Otto Magnus.
Magnus had five children, Karl (1903-1989) lung specialist; Margarete (Gretl)(1905-1968)who worked as his secretary and translator; Dorothea who died aged 11; Erica (1909-1991) architect; and Otto (1913-2014) neurologist.
Magnus is most widely known for his work as a physiologist. His book Körperstellung ("Posture")., a study of functional neurology, is his best known work.

Osamu Hayaishi MJA (早石 修, Hayaishi Osamu, January 8, 1920 – December 17, 2015), was a Japanese biochemist, physiologist, and military physician. He discovered Oxygenases at the National Institute of Arthritis and Metabolic Diseases, National Institutes of Health in 1955.Citing his "outstanding and pioneering contributions to biomedical sciences and enzymology," the Wolf Foundation awarded Hayaishi the 1986 Wolf Prize in Medicine "for his discovery of the oxygenase enzymes and elucidation of their structure and biological importance".Hayaishi was President of International Union of Biochemistry and Molecular Biology from 1973 to 1976.

Friedrich August Ferdinand Christian Went (June 18, 1863 – July 24, 1935) was a Dutch botanist.
Went was born in Amsterdam. He was professor of botany and director of the Botanical Garden at the University of Utrecht. His eldest son was the Dutch botanist Frits Warmolt Went, who in 1927 as a graduate student worked on plant hormones, specifically the role of auxin in phototropism.
He became member of the Royal Netherlands Academy of Arts and Sciences in 1898.Went died, aged 72, in Wassenaar.

Nathan Zuntz (6 October 1847, in Bonn – 22 March 1920, in Berlin) was a German physiologist born in Bonn. He was a pioneer of modern altitude physiology and aviation medicine.
