Paul Gabriel Hautefeuille (2 December 1836 in Étampes – 8 December 1902 in Paris) was a French mineralogist and chemist.

Icilio Guareschi (24 December 1847 – 20 June 1918) was an Italian chemist.
Icilio Guareschi studied at the University of Bologna and received his Ph.D there in 1871. He became professor at the University of Siena and in 1879 at the University of Turin, where he worked until his death in 1918.
Guareschi worked in the field of organic chemistry, pharmacy, toxicology and the history and chemistry. In 1894 he discovered a reaction to synthesise 2-Pyridones, today known as the Guareschi-Thorpe condensation.

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.

Alexander Robertson FRS (12 February 1896 – 9 February 1970) was a British chemist. He was awarded the Davy Medal in 1952 "In recognition of his researches into the chemistry of natural products, particularly the wide range of glycosides, bitter principles and colouring matters containing heterocyclic oxygen atoms". He is known for his organic chemistry research, particularly in the investigation of natural products.

Philippe Antoine Francoise Barbier (2 March 1848 – 18 September 1922) was a French organic chemist. He is best known for his two named reactions in organic synthesis, the Barbier reaction and the Barbier-Wieland degradation, as well as for his role in the creation of organomagnesium reagents with his student, Victor Grignard.
Although Grignard was awarded the Nobel prize in 1912 (along with Sabatier) for his discovery, Barbier and Sabatier’s collaborator, Senderens, were snubbed. Grignard himself decried this as an injustice, writing to a friend just days after returning from his Nobel acceptance: “…to tell the truth, and between us, I would even have preferred to wait a little longer, to see the prize shared between Sabatier and Senderens, and then share it myself with Barbier at a later time”. Nevertheless, Barbier’s contributions to the scientific community were plentiful and varied, including work in mineralogy, natural products isolation, and polycyclic aromatic hydrocarbons.

Józef Zawadzki (July 14, 1886 in Warsaw – February 22, 1951 in Zalesie, near Warsaw) was a Polish physical chemist and technologist. Father of Tadeusz (Zośka) and Anna Zawadzka.
Zawadzki was a co-founder, President and Vice-President of the Polskie Towarzystwo Chemiczne. He was a professor (from 1923) and rector (1936–1939) of Warsaw University of Technology, and a member of the Polish Academy of Learning (since 1947).
The oldest and largest traditional lecture hall at the Warsaw University of Technology is named Prof. Józef Zawadzki Auditorium.

Jan Czochralski ( YAN chokh-RAHL-skee, Polish pronunciation: [ˈjan t͡ʂɔˈxralskʲi]; 23 October 1885 – 22 April 1953) was a Polish chemist who invented the Czochralski method, which is used for growing single crystals and in the production of semiconductor wafers. It is still used in over 90 percent of all electronics in the world that use semiconductors. He is the most cited Polish scholar.There is evidence that Czochralski sheltered two Jewish women in his home until the Warsaw Uprising to save them from the Germans and some evidence that he was instrumental in financially helping a previously owned Jewish business in the ghetto.

Eugène-Melchior Péligot (24 March 1811 – 15 April 1890), also known as Eugène Péligot, was a French chemist who isolated the first sample of uranium metal in 1841.Péligot proved that the black powder of Martin Heinrich Klaproth was not a pure metal (it was an oxide of uranium, known in chemistry as UO2). He then succeeded in producing pure uranium metal by reducing uranium tetrachloride (UCl4) with potassium metal. Today better methods have been found.
Péligot was a professor of analytical chemistry at the Institut National Agronomique. He collaborated with Jean-Baptiste Dumas, and together they discovered the methyl radical during experiments on wood spirit (methanol). The terminology "methyl alcohol" was created by both chemists from "wood wine". They also prepared the gaseous dimethyl ether, and many esters. In 1838, they successfully transformed camphor into p-cymene using phosphorus pentoxide.
In 1844 he synthesized chromium(II) acetate, which was much later recognized (by F. Albert Cotton in 1964) to be the first chemical compound which contains a quadruple bond.

Fausto de Elhuyar (11 October 1755 – 6 February 1833) was a Spanish chemist, and the first to isolate tungsten with his brother Juan José Elhuyar in 1783. He was in charge, under a King of Spain commission, of organizing the School of Mines in México City and so was responsible for building an architectural jewel known as the "Palacio de Minería". Elhuyar left Mexico after the Mexican War of Independence, when most of the Spanish residents in Mexico were expelled.
