Hans Horst Meyer (17 March 1853 – 6 October 1939) was a German pharmacologist. He studied medicine and did research in pharmacology. The Meyer-Overton hypothesis on the mode of action on general anaesthetics is partially named after him. He also discovered the importance of glucuronic acid as a reaction partner for drugs, and the mode of action of tetanus toxin on the body.
Caesar Rudolf Boettger (20 May 1888 – 8 September 1976) was a German zoologist born in Frankfurt am Main. He specialized in malacology, particularly studying the land snails and slugs.
In 1912 he obtained his PhD from the University of Bonn, and in 1914 embarked on a scientific expedition to Africa and the Orient. During World War I, he was stationed in France and Turkey. In 1932 he became a private lecturer at the University of Berlin, where in 1938 he was appointed professor of zoology. In 1947 he became a professor of zoology at Braunschweig University of Technology, where he established a museum of natural history.
After retirement in 1956, he undertook five research trips to North America (including Mexico and Hawaii). In 1965 he was visiting curator at the University of Michigan and in 1967/68 took part in a research project of the Naval Medical Field Research Laboratory in North Carolina. Boettger has over a dozen species named after him, as well as a gastropod genus:
Boettgerilla Simroth, 1910.Caesar Boettger is commemorated in the scientific name of a species of lizard, Gallotia caesaris.
He was a nephew of German herpetologist Oskar Boettger.
Hugo Merton (18 November 1879 in Frankfurt am Main – 23 March 1940 in Edinburgh) was a German zoologist.
He studied sciences at the University of Heidelberg. From October 1907 to August 1908, with herpetologist Jean Roux, he conducted scientific investigations in the Aru and Kei Islands. In 1913 he obtained his habilitation at Heidelberg with a dissertation on the flatworm genus Temnocephala. Because of the 1935 Nuremberg Laws imposed by the Nazis, he was forced to relinquish his position as deputy director at the Senckenberg Museum in Frankfurt as well as his professorship at the University of Heidelberg.In 1937, by way of an invitation from Professor F. A. E. Crew, he went to the University of Edinburgh, where he spent time working in the institute of animal genetics. Upon this return to Germany in 1938, he was arrested and imprisoned in the concentration camp at Dachau. During the following year, he was deported to Scotland, where he resumed his work at the university. Due to deteriorated health, he died soon afterwards in March 1940.Organisms with the specific epithet of mertoni are named in his honor, an example being the sea snake species Parahydrophis mertoni. In 1911, Max Carl Wilhelm Weber named the fish species Pseudomugil gertrudae after Merton's wife, Gertrude.
Hillel Oppenheimer (Hebrew: הלל אופנהיימר, born Heinz Reinhard Oppenheimer; 4 April 1899 – 15 June 1971), was an Israeli professor of botany.
Max Marcuse (April 14, 1877, Berlin – June 24, 1963, Tel Aviv) was a German dermatologist and sexologist. He became an editor for Magnus Hirschfeld’s Journal of Sexology in 1919 and continued editing the journal until 1932. Marcuse immigrated to Palestine in 1933, following the Nazi rise to power. Several of Marcuse's unpublished writings are being preserved at the Kinsey Institute.
Harry Benjamin (January 12, 1885 – August 24, 1986) was a German-American endocrinologist and sexologist, widely known for his clinical work with transgender people.
Robert Wayne McCollum Jr. (January 29, 1925 – September 13, 2010) was an American virologist and epidemiologist who made pioneering studies into the nature and spread of polio, hepatitis and mononucleosis while at the Yale School of Medicine, after which he served for nearly a decade as Dean of the Dartmouth Medical School.
Hugo Gunckel Lüer (August 10, 1901 – July 17, 1997) was a Chilean pharmacist, botanist, and university professor.
Gualterio Looser Schallemberg (September 4, 1898, Santiago – July 22, 1982) was a Chilean botanist and engineer of Swiss parentage. He owned a factory that made agricultural implements.
In 1928 Looser joined the American Fern Society, and started to publish papers on the pteridophytes of Chile. His herbarium containing ca. 8000 specimens was given to Conservatoire et Jardin botaniques de la Ville de Genève.
Emilio Veratti (24 March 1872, Varese – 24 February 1967) was an Italian anatomist and pathologist. He is known for his discovery of the sarcoplasmic reticulum.
He studied medicine at the Universities of Pavia and Bologna, where he received his doctorate in 1896. Following graduation he worked for Camillo Golgi (1843-1926) at the Institute of General Pathology in Pavia. Here he distinguished himself by way of research in the fields of histology and microbiology. Eventually he attained the title of "libero docente" (equivalent of privat-docent) in histology and general pathology.
In 1921 he established a bacteriology laboratory in the medical clinic at Pavia. In 1930 he was successor to Aldo Perroncito (1882-1929) as professor of general pathology, a position he kept until his retirement in 1942.In March 1902, he provided the first accurate description of the reticular network (sarcoplasmic reticulum) in skeletal muscle fibers. His published findings attracted little attention at the time, and as years passed by, his discovery was all but forgotten. In 1961 "Veratti's reticulum" was re-discovered through the use of electron microscopy.
