20th-century French chemists

Irene_Joliot-Curie

Irène Joliot-Curie (French: [iʁɛn ʒɔljo kyʁi] ; née Curie; 12 September 1897 – 17 March 1956) was a French chemist, physicist and politician, the elder daughter of Pierre Curie and Marie Skłodowska–Curie, and the wife of Frédéric Joliot-Curie. Jointly with her husband, Joliot-Curie was awarded the Nobel Prize in Chemistry in 1935 for their discovery of induced radioactivity, making them the second-ever married couple (after her parents) to win the Nobel Prize, while adding to the Curie family legacy of five Nobel Prizes. This made the Curies the family with the most Nobel laureates to date. In addition to the following honours in the family: the first ever woman Nobel Prize laureate, the first ever person and, to this day, only woman double Nobel Prize laureate, the sole person to this day with two Nobel Prizes in different sciences, thanks to her mother.
Her mother Marie Skłodowska–Curie and herself also form the only mother–daughter pair to have won Nobel Prizes whilst Pierre and Irène Curie form the only father-daughter pair to have won Nobel Prizes by the same occasion, whilst there are 6 father-son pairs who have won Nobel Prizes by comparison.She was also one of the first three women to be a member of a French government, becoming undersecretary for Scientific Research under the Popular Front in 1936. Both children of the Joliot-Curies, Hélène and Pierre, are also prominent scientists.In 1945, she was one of the six commissioners of the new French Alternative Energies and Atomic Energy Commission (CEA) created by de Gaulle and the Provisional Government of the French Republic. She died in Paris on 17 March 1956 from an acute leukemia linked to her exposure to polonium and X-rays.

Charles-Victor_Mauguin

Charles-Victor Mauguin (French: [ʃaʁl.vik.tɔʁ mo.gɛ̃]; 19 September 1878 – 25 April 1958), more often Charles Mauguin, was a French mineralogist and crystallographer. He and Carl Hermann invented an international standard notation for crystallographic groups called Hermann–Mauguin notation (also sometimes called international notation).

Camille_Matignon

Arthème Camille Matignon (French pronunciation: [kamij matiɲɔ̃]; 3 January 1867 – 18 March 1934) was a French chemist noted for his work in thermochemistry. He was a member of the Académie des Sciences, President of the French Chemical Society and an honorary Fellow of the British Chemical Society.

Léon_Maquenne

Léon-Gervais-Marie Maquenne (2 December 1853 – 10 January 1925) was a French chemist and plant physiologist born in Paris.
From 1871 he worked in the laboratory of agricultural chemistry at the Ecole d'agriculture in Grignon. Here, he was a student of Pierre Paul Dehérain (1830-1902). In 1883 he became préparateur at the Muséum national d'histoire naturelle, where from 1885 to 1898 he served as an assistant to the chair of Physiologie végétale. In 1898 he succeeded Georges Ville (1824-1897) as chair of Physique végétale, a position he held on to until 1925. In 1904 he became a member of the Académie des sciences.
Among Maquenne's contributions was research involving the chemical make-up of sugar alcohols. He was able to resolve the chemical constitution of inositol and demonstrated it to be a hexahydroxycyclohexane.He is credited with invention of the so-called "Maquenne block", an apparatus used for determining the melting point of chemical compounds.

Louis_Camille_Maillard

Louis Camille Maillard ( my-YAR; French: [lwi kamij majaʁ]; 4 February 1878 – 12 May 1936) was a French physician and chemist. He made important contributions to the study of kidney disorders. He also became known for the "Maillard reaction", the chemical reaction which he described in 1912, by which amino acids and sugars react in foods via contact with fats, giving a browned, flavorful surface to everything from bread and seared steaks to toasted marshmallows.

Georges_Lemoine

Clément Georges Lemoine (16 January 1841 in Tonnerre – 13 November 1922 in Paris) was a French chemist and hydrologist. He was the father of geologist Paul Lemoine (1878–1940).
He studied at the École Polytechnique and the École des ponts et chaussées, obtaining a doctorate in physical sciences in 1865. For many years he was associated with the École Polytechnique in Paris, where he ultimately served as a professor of chemistry from 1898 to 1911.In 1866 he began work as an engineer in charge of hydrometric services in the Seine Basin. In 1881 he was appointed chief engineer of bridges and roads, and in 1901, was named inspector general of bridges and roads. He is credited with organizing a flood warning service throughout France.As a chemist he discovered phosphorus sesquisulfide, a compound that will later be used in the manufacture of matches. He continued research on the allotropic transformation of phosphorus, and was also the author of works on chemical equilibria.In 1899 he became a member of the Académie des sciences (chemistry section), of which in 1921, he was named its president.

Stéphane_Leduc

Stéphane Leduc (1 November 1853 – 8 March 1939) was a French biologist who sought to contribute to understanding of the chemical and physical mechanisms of life. He was a scientist in the fledgling field of synthetic biology, particularly in relation to diffusion and osmosis. He was a professor at the École de Médecine de Nantes and worked on osmotic crystallisation and the physiological effects of electric current. He was an Officier de la Légion d'honneur.
