Alexander McKenzie FRS (6 December 1869, Dundee – 11 June 1951) was a Scottish chemist, specializing in stereochemistry. Kinetic resolution by synthetic means was first reported in 1899 by Marckwald and McKenzie.

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.

Charles Frédéric Kuhlmann (22 May 1803 – 27 January 1881) was a French chemist who patented the reaction for converting ammonia to nitric acid, which was later used in the Ostwald process.He was both a research scientist and a professor at Université Lille Nord de France. He promoted chemical engineering education for science graduates in Lille and supported the development of École centrale de Lille (IDN).
As an entrepreneur starting in 1829, he established his own chemical company producing sulfuric acid. This company later merged into Pechiney Ugine Kuhlmann group.

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.

Prof Emil Clement Jungfleisch FRSE MIF (1839-1916) was a French biochemist and pharmacist. He studied molecular dissymmetry.

Dr. Clyde Allen Hutchison Jr. (May 5, 1913 – August 29, 2005) was an American chemist notable for his research in magnetic resonance spectroscopy.

Hutchison was a member of the National Academy of Sciences and
a chairman and professor of the department of chemistry at the University of Chicago.
He was also a fellow of the American Academy of Arts and Sciences,
a fellow of the American Physical Society,
a member of the American Chemical Society,Guggenheim fellow at Oxford University,
the George Eastman Professor at Oxford University,
and a member of the American Association for the Advancement of Science.
He was also a recipient of the Peter Debye Award in Physical Chemistry from the American Chemical Society. He served as editor of the Journal of Chemical Physics from 1953 - 1955 and again from 1958 - 1959.
Hutchison participated in the Manhattan Project.
The University of Chicago said that Hutchison "pioneered research in magnetic resonance spectroscopy".

Auguste Houzeau (French: [ogyst uzo]; 3 March 1829, Elbeuf – 17 February 1911, Rouen) was a French agronomist and chemist.
He studied at the Conservatoire national des arts et métiers in Paris, where he took chemistry classes from Jean-Baptiste Boussingault. He later served as a professor at the École préparatoire à l'enseignement supérieur des sciences et des lettres in Rouen, and in 1883 was appointed director of the Station agronomique de la Seine-Inférieure. He was also president of the Société centrale d'agriculture de la Seine-Maritime.He is remembered for his investigations on the nature of ozone and its diffusion into the atmosphere; as well as for various studies of fertilizers and for his research involving apple pomace. He was the recipient of several awards during his career, such as:

(1862): The Médaille de vermeil from the Société industrielle d'Elbeuf.
(1870): Chevalier of the Légion d'honneur, being promoted to officer in 1895.
(1872): The Médaille d'or of the Sociétés savantes à la Sorbonne.
(1872): Platinum medal from the Société d'encouragement of Paris.
(1877): The Prix Jecker for his work associated with ozone.
The Ordre du Lion et du Soleil of Persia.

Heinrich Hubert Maria Josef Houben (27 October 1875, in Waldfeucht (Rheinland) Germany – 28 June 1940, in Tübingen) was a German chemist. He made achievements within ketone synthesis, terpenes, and camphor studies. After being wounded several times on the front lines in World War I, Houben was made head of the war laboratory. He improved the Hoesch reaction which is now normally called Houben-Hoesch reaction. Houben organized and made a major rework of the book Methods of Organic Chemistry which is now referred to as Houben-Weyl Methods of Organic Chemistry.

Alfred Gottschalk (22 April 1894 – 4 October 1973) was a German biochemist who was a leading authority in glycoprotein research. During his career he wrote 216 research papers and reviews, and four

books.Gottschalk was born in Aachen, the third of four children to Benjamin and Rosa Gottschalk, who had Jewish heritage. He was raised Catholic. He choose to study medicine, from 1912 he attended the Universities of Munich, Freiburg im Breisgau and Bonn. During the war he served in the medical corps of the German Army. He completed his medical degree in 1920, graduating MD from the University of Bonn. He completed clinical work experience at the medical schools of Frankfurt am Main and Würzburg and physiology-biochemistry studies at Bonn, that led to his first publications, an award from the University of Madrid and an invitation to work at the Kaiser Wilhelm Institute for Experimental Therapy and Biochemistry with Carl Neuberg.
In 1923 he married Lisbeth Berta Orgler; together they had one son. They separated in 1950. Gottschalk left the Kaiser Wilhelm Institute for Biochemistry in 1926 to become Director of the Biochemical Department at the General Hospital in Stettin. He left the hospital in 1934 following upheaval in Nazi Germany and entered private practice, left for England in the spring of 1939, and on to Melbourne in July. He was offered a position as a biochemist by Charles Kellaway, director of the Walter and Eliza Hall Institute (WEHI). He initially worked with yeast enzymes and fermentation, but in 1947 he joined the virus department, where he worked with Frank Macfarlane Burnet. He also taught biochemistry and organic chemistry at the Melbourne Technical College and later at the University of Melbourne. In 1945 he became a naturalized British citizen. In 1949 he received a DSc from the University of Melbourne.
He was elected a Fellow of the Australian Academy of Science in 1954. He discovered viral neuraminidase there in 1957. As Burnet stated: “In the world of biochemistry the most important contribution of the Walter and Eliza Hall Institute is regarded as Gottschalk’s discovery of the structure of the sialic acids and his recognition that an enzyme which I had characterised biologically was chemically a neuraminidase. Gottschalk’s work was masterly and it was definitive.”On his retirement in 1959, he was invited by his friend and former WEHI colleague Frank Fenner to research at the John Curtin School of Medical Research at the Australian National University. He returned to Germany in 1963, where he was appointed Guest-Professor at the Max Planck Institute for Virus Research in Tübingen. He continued active research and for his contributions to science was elected to the Fellowship of the American Association for the Advancement of Science in 1967 and received an honorary doctorate from the University of Münster (MD) in 1969.
He died in Tübingen on 4 October 1973. The Gottschalk Medal for medical research awarded by the Australian Academy of Science is named in his honour.

Robert B. Goldschmidt (1877–1935) was a Belgian chemist, physicist, and engineer who first proposed the idea of standardized microfiche (microfilm).
Goldschmidt was a polymath who also made advances in aviation and radio, among other fields. In 1913 he constructed a major radio facility at Laeken, Belgium, where in 1914 he and Raymond Braillard inaugurated Europe's first regular radio concert broadcasts. He was also a participant in the first and second international Solvay Conferences reviewing outstanding issues in chemistry and physics.
