Vocation : Science : Chemistry

Lorene_Rogers

Lorene Lane Rogers (April 3, 1914 – January 11, 2009) was an American biochemist and educator who served as the 21st President of the University of Texas at Austin. She has been described as the first woman in the United States to lead a major research university.

Marie_Pasteur

Marie Pasteur, née Laurent (15 January 1826 in Clermont-Ferrand, France – 28 September 1910 in Paris), was the scientific assistant and co-worker of her spouse, the famous French chemist and bacteriologist Louis Pasteur.

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.

Paul_Lebeau

Paul Marie Alfred Lebeau (19 December 1868 – 18 November 1959) was a French chemist. He studied at the elite École supérieure de physique et de chimie industrielles de la ville de Paris (ESPCI). Together with his doctoral advisor Henri Moissan he was working on fluorine chemistry discovering several new compounds, like bromine trifluoride, oxygen difluoride, selenium tetrafluoride and sulfur hexafluoride.
In 1899 he was able to obtain pure beryllium by electrolysis sodium fluoroberyllate (Na2[BeF2]).
In World War I he improved the gas mask design used by the French army.
