Karl Holl (15 May 1866 – 23 May 1926) was a professor of theology and church history at Tübingen and Berlin and is considered one of the most influential church historians of his era.

William Cullen (; 15 April 1710 – 5 February 1790) was a Scottish physician, chemist and agriculturalist, and professor at the Edinburgh Medical School. Cullen was a central figure in the Scottish Enlightenment: He was David Hume's physician, and was friends with Joseph Black, Henry Home, Adam Ferguson, John Millar, and Adam Smith, among others.
He was President of the Royal College of Physicians and Surgeons of Glasgow (1746–47), President of the Royal College of Physicians of Edinburgh (1773–1775) and First Physician to the King in Scotland (1773–1790). He also assisted in obtaining a royal charter for the Philosophical Society of Edinburgh, resulting in the formation of the Royal Society of Edinburgh in 1783.Cullen was a beloved teacher, and many of his students became influential figures. He kept in contact with many of his students, including Benjamin Rush, a central figure in the founding of the United States of America; John Morgan, who founded the first medical school in the American colonies, the Medical School at the College of Philadelphia; William Withering, the discoverer of digitalis; Sir Gilbert Blane, medical reformer of the Royal Navy; and John Coakley Lettsom, the philanthropist and founder of the Medical Society of London.Cullen's student and later rival John Brown developed the medical system known as Brunonianism, which conflicted with Cullen's. The competition between the two systems had knock-on effects in how patients were treated worldwide, especially in Italy and Germany, during the end of the eighteenth and beginning of the nineteenth century.Cullen was also an author. He published a number of medical textbooks, mostly for the use of his students, though they were popular in Europe and the American colonies. His best known work was First Lines of the Practice of Physic, which was published in a series of editions between 1777 and 1784, and inventing the basis of modern refrigeration.

André Laronde (19 June 1940, in Grenoble – 1 February 2011, in Paris) was a French historian and archaeologist. He was a specialist of Greek settlements in Cyrenaica (now Libya).

Joseph Alexandre Laboulbène (25 August 1825 Agen – 7 December 1898, Paris) was a French physician and entomologist.
A friend of the entomologist Jean-Marie Léon Dufour (1780-1865), he studied medicine in the University of Paris and was awarded the title Docteur in 1854. He taught in the medical faculty until 1879.
Laboulbène was interested in harmful insects notably in the Order Diptera. The order of mushrooms Laboulbeniales, is dedicated to him, by Engler in 1898.In 1853, Laboulbenia which is a genus of fungi in the family Laboulbeniaceae, was named in his honour.

Max Jakob (July 20, 1879 – January 4, 1955) was a German physicist known for his work in the field of thermal science.
Born in Ludwigshafen, Germany, Jakob studied engineering at Technical University Munich, from which he graduated in 1903. From 1903 to 1906, he was an assistant to O. Knoblauch at the Laboratory for Technical Physics. In 1910, Jakob embarked on a 25-year career at the Physikalisch-Technische Reichsanstalt in Charlottenburg, Berlin. During this time he founded and directed applied thermodynamics, heat transfer, and fluid flow laboratories.Fleeing Nazi persecution, Jakob left Germany in 1936 and immigrated to the United States, where he became a professor at Armour Institute of Technology (now Illinois Institute of Technology) and a consultant in heat transfer for Armour Research Foundation. There he conducted research, covering areas such as steam and air at high pressure, devices for measuring thermal conductivity, the mechanisms of boiling and condensation, and flow in pipes and nozzles.His many years of teaching, consulting, and writing resulted in contributions to the literature of the profession; nearly 500 books, articles, reviews and discussions have been published based on his research. He has published a number of books in thermal sciences including Elements of Heat Transfer and Insulation (1942) and Heat Transfer (1956).
He is credited with devising the Jakob dimensionless number, aka Jakob number, which is used in phase change heat transfer calculations:

The Max Jakob Memorial Award, the highest honor in the field of heat transfer, was established in 1961 by the American Society of Mechanical Engineers (ASME) Heat Transfer Division in honor of Jakob.

Jean Hyppolite (French pronunciation: [ʒɑ̃ ipɔlit]; 8 January 1907 – 26 October 1968) was a French philosopher known for championing the work of G.W.F. Hegel, and other German philosophers, and educating some of France's most prominent post-war thinkers. His major works include Genèse et structure de la Phénoménologie de l'esprit de Hegel (1946) and Études sur Marx et Hegel (1955) and the first translation of Hegel's The Phenomenology of Spirit into French in 1939.

John Mackintosh Howie (23 May 1936 – 26 December 2011) was a Scottish mathematician and prominent semigroup theorist.

Carl (or Karl) Otto Harz (28 November 1842 in Gammertingen – 5 December 1906 in Munich) was a German mycologist, pharmacist and botanist.
After spending time as an intern in several pharmacies, he studied botany at the University of Berlin. Later, he relocated to Munich, where he served as a lecturer at the Technische Universität München (from 1873) and at the Tierärztlichen Hochschule (from 1874). In 1880 he was appointed professor of botany and pharmacognosy at the Tierärztlichen Hochschule.In 1877, with pathologist Otto Bollinger, he conducted early studies of actinomycosis in cattle, and is credited for naming the causal agent Actinomyces bovis. From his observations, he believed the culprit to be a mould, related to the genera Botrytis or Monosporium.As a taxonomist, he circumscribed a number of varieties from the species Cucurbita pepo. His name is associated with the following mycological genera:

Harzia (family Ceratostomataceae), named by Julien Noël Costantin (1888).
Harziella (family Chaetomiaceae), named by Otto Kuntze (1891).

Octave Hamelin (22 July 1856 in Montpellier – 11 September 1907 in Prades, Pyrénées-Orientales) was a French philosopher. He taught as a professor at the University of Bordeaux (1884-) and the University of Sorbonne (1905-). Hamelin was a close friend of the sociologist Émile Durkheim, with whom he shared an interest in the French philosopher Charles Renouvier. He is also known as a translator of classical Greek philosophers.Hamelin drowned in 1907, attempting to save two young women.

François Cyrille Grand'Eury (9 March 1839, Houdreville – 22 July 1917, Malzéville) was a French geologist, paleontologist and mathematics teacher.
He studied at the École Loritz in Nancy and at the École des mines in Saint-Étienne, and later worked as a mining engineer in Roche-la-Molière. From 1863 to 1899 he taught classes in mathematics at the École des mines in Saint-Étienne, where in 1883 he received the title of professor.From 1877 he was a member of the Société géologique de France and in 1885 was elected a correspondent member of the Académie des Sciences.He is remembered for his stratigraphic research of coal fields and for his investigations involving the formation of coal. He is credited with establishing the chronological succession of floras associated with the coal seams of the Stephanian stage (named after the development of this stage at Saint-Étienne). He conducted exhaustive studies of coal flora (Cordaites, Calamites, et al), and in 1877 described the genus Tubiculites.
