Friedrich Hermann Leuchs (8 August 1879 – 2 May 1945) was a German chemist.

Constantin Marie Le Paige (9 March 1852 – 26 January 1929) was a Belgian mathematician.
Born in Liège, Belgium, Le Paige began studying mathematics in 1869 at the University of Liège. After studying analysis under Professor Eugène Charles Catalan, Le Paige became a professor at the Université de Liège in 1882.
While interested in astronomy and the history of mathematics, Le Paige mainly worked on the theory of algebraic form, especially algebraic curves and surfaces and more particularly for his work on the construction of cubic surfaces. Le Paige remained at the university until his retirement in 1922.

Max Joseph Pettenkofer, ennobled in 1883 as Max Joseph von Pettenkofer (3 December 1818 – 10 February 1901) was a Bavarian chemist and hygienist. He is known for his work in practical hygiene, as an apostle of good water, fresh air and proper sewage disposal. He was further known as an anti-contagionist, a school of thought, named later on, that did not believe in the then novel concept that bacteria were the main cause of disease. In particular he argued in favor of a variety of conditions collectively contributing to the incidence of disease including: personal state of health, the fermentation of environmental ground water, and also the germ in question. He was most well known for his establishment of hygiene as an experimental science and also was a strong proponent for the founding of hygiene institutes in Germany. His work served as an example which other institutes around the world emulated.

Ferdinand Adolph Theophil Hueppe (24 August 1852 – 15 September 1938) was a German physician, bacteriologist and hygienist. From 1900 to 1904, he was the first Deutscher Fußball-Bund (DFB, German Football Association) president.

Abraham Albert Hijmans van den Bergh (1 December 1869, in Rotterdam – 28 September 1943, in Utrecht) was a Dutch physician specializing in internal medicine. Hijmans van den Bergh is best known for his Van den Bergh reaction.
In 1919 he became member of the Royal Netherlands Academy of Arts and Sciences.Hijmans van den Bergh was of Jewish descent, but neither he or his parents were religiously observant, nor members of a Jewish worship community. Later in life he joined the Remonstrant Church. His final years were spent under the German occupation of the Netherlands; he was spared persecution due to being in a "mixed marriage".

Robert Eugen Gaupp (3 October 1870 – 30 August 1953) was a German psychiatrist and neurologist who was a native of Neuenbürg, Württemberg.
Gaupp was an assistant to Carl Wernicke (1848–1905) and Karl Bonhoeffer (1868–1948) at Breslau, and afterwards worked with Emil Kraepelin (1856–1926) at the Universities of Heidelberg and Munich. From 1908 to 1936 he was a professor of psychiatry at the University of Tübingen. One of his assistants was Ernst Kretschmer. Following World War II, he was departmental head of health and welfare for the city of Stuttgart (1945–48).
Gaupp performed numerous investigations of psychological disorders, and is remembered for his case studies of mass-murderer Ernst August Wagner (1874–1938). He was particularly interested in correlations between personality and psychosis, and was an advocate of "pastoral psychology". For a period of time, he was also editor of the Zentralblatt für Nervenheilkunde und Psychiatrie.
Sometime shortly after the passage by decree, on 15 September 1935, of the "Nuremberg Laws"(officially "Laws for the Protection of German Blood and Honor"), Gaupp came to the support of a local physician, Albrecht Schroeder (pictured at left in image below), a collegiate fraternity brother in a non-fighting order, die Igel (the Hedgehogs), to which Gaupp also belonged. With the passage of the Nuremberg Laws and the preemption of organizational authority to permit Jewish membership in non-dueling fraternal orders (Jews had never been permitted to join German dueling orders), Schroeder's status was made precarious because he was married to a Jew, née Felicia Rosenstein of Bad Cannstatt, an outer district of Stuttgart. At a meeting convened of the general membership to decide upon Schroeder's suitability for membership given Schroeder's marital status and his "Mischling" (mixed race) children, Gaupp, otherwise unaffiliated with Schroeder (Gaupp was 65 at the time, Schroeder 44; and the two had never before met), declared before those assembled: "Wenn der Schroeder raus muss, dann geh ich auch." (If Schroeder goes, then I go, too.) Schroeder withdrew his petition sometime before final disposition by the fraternity towards his case, and Gaupp himself left the organization voluntarily around the same time, as he had pledged doing on behalf of Schroeder. The two men remained close friends until Gaupp's death in 1953.

Karl Johann Freudenberg (29 January 1886 Weinheim, Baden – 3 April 1983 Weinheim) was a German chemist who did early seminal work on the absolute configurations to carbohydrates, terpenes, and steroids, and on the structure of cellulose (first correct formula published, 1928) and other polysaccharides, and on the nature, structure, and biosynthesis of lignin. The Research Institute for the Chemistry of Wood and Polysaccharides at the University of Heidelberg was created for him in the mid to late 1930s, and he led this until 1969.

Ernest Fourneau (4 October 1872 – 5 August 1949) was a French pharmacist who graduated in 1898 for the Paris university specialist in medicinal chemistry and pharmacology. He played a major role in the discovery of synthetic local anesthetics such as amylocaine, as well as in the synthesis of suramin. He authored more than two hundred scholarly works, and has been described as having "helped to establish the fundamental laws of chemotherapy that have saved so many human lives".Fourneau was a pupil of Friedel and Moureu, and studied in the German laboratories of Ludwig Gattermann in Heidelberg, Hermann Emil Fischer in Berlin and Richard Willstätter in Munich.
He headed the research laboratory of Poulenc Frères in Ivry-sur-Seine from 1903 to 1911.
One of the products was a synthetic local anesthetic that was named Stovaine (amylocaine).
This was a pun on the English translation of "fourneau" as "stove". (The same pun was used in the brand name of the drug acetarsol, Stovarsol.)
Other important medicines were antipyretics.
In 1910 Fourneau accepted the directorship of the Pasteur Institute's medical chemistry section, with the condition that he maintained his ties with Poulenc Frères. He recruited Germaine Benoit to work in the Institute as a new graduate.He was a member of the Académie Nationale de Médecine.

Friedrich Fichter (6 July 1869 – 1952) was a professor of inorganic chemistry at the University of Basel. His main field of interest was electrochemistry. He initiated the founding of the scientific journal Helvetica Chimica Acta.

Adolfo Ferrata (26 April 1880 in Brescia – 9 March 1946) was an Italian pathologist and hematologist.
In 1904 he earned his medical degree from the University of Parma, spending the following years performing scientific research in clinics at Parma, Berlin and Naples. From 1921 to 1924 he was a professor of special medical pathology at the Universities of Messina and Siena, afterwards serving as a professor of clinical medicine at the University of Pavia, a position he kept for the remainder of his career.Among his contributions to medical science are investigations on the structure and embryology of the kidney, research on the morphology of intestinal villi and haematopoietic studies in normal and pathological conditions. In his research of haematopoiesis, Ferrata helped demonstrate the systemic nature of leukemia, leading him to support an hypothesis that elements of the blood (erythrocytes, leukocytes, and blood platelets) all originate from the hemocytoblast, a direct descendant of a mesenchymal cell, which he referred to as an emoistioblasto (hemohistioblast).In 1907 he was the first scientist to show that the complement could be split into two components that were singularly inactive, only regaining their activity when reunited.In 1920 Ferrata founded the journal "Haematologica".
