See also:GERHARDT, See also:CHARLES See also:FREDERIC (1816-1856) , See also:French chemist, was See also:born at See also:Strassburg on the 21st of See also:August 1816. After attending the gymnasium at Strassburg and the See also:polytechnic at See also:Karlsruhe, he was sent to the school of See also:commerce at See also:Leipzig, where he studied See also:chemistry under See also:Otto See also:Erdmann. Returning See also:home in 1834 he entered his See also:father's See also:- WHITE

white See also:lead factory, but soon found that business was not to his liking, and after a See also:sharp disagreement with his father enlisted in a See also:cavalry See also:regiment. In a few months military See also:life became equally distasteful, and he See also:purchased his See also:discharge with the assistance of See also:Liebig, with whom, after a See also:short See also:interval at See also:Dresden, he went to study at See also:Giessen in 1836. But his stay at Giessen was also short, and in 1837 he re-entered the factory. Again, however, he quarrelled with his father, and in 1838 went to See also:Paris with introductions from Liebig. There he attended See also:Jean See also:Baptiste See also:Dumas' lectures and worked with Auguste Cahours (1813–1891) on essential See also:oils, especially See also:cumin, in See also:Michel See also:Eugene See also:Chevreul's laboratory, while he earned a See also:precarious living by teaching and making See also:translations of some of Liebig's writings. In 1841, by the See also:influence of Dumas, he was charged with the duties of the See also:chair of chemistry at the See also:Montpellier See also:faculty of sciences, becoming titular See also:professor in 1844. In 1842 he annoyed his See also:friends in Paris by the See also:matter and manner of a See also:paper on the See also:classification of organic compounds, and in 1845 he and his opinions were the subject of an attack by Liebig, unjustifiable in its personalities but not altogether surprising in view of his wayward disregard of his See also:patron's See also:advice. The two were reconciled in 185o, but his faculty for disagreeing with his friends did not make it easier for him to get another See also:appointment after resigning the chair at Montpellier in 1851, especially as he was unwilling to go into the provinces. He obtained leave of See also:absence from Montpellier in 1848 and from that See also:year till 1855 resided in Paris. During that See also:period he established an " 1cole de chimie pratique " of which he had See also:great hopes; but these were disappointed, and in 1855, after refusing the offer of a chair of chemistry at the new See also:Zurich Polytechnic in18J4,he accepted the professorships of chemistry at the Faculty of Sciences and the l See also:cole Polytechnique at Strassburg, where he died on the 19th of August in the following year. Although Gerhardt did some noteworthy experimental work—for instance, his preparation of See also:acid anhydrides in 1852—his contributions to chemistry consist not so much in the See also:discovery of new facts as in the introduction of new ideas that vitalized and organized an inert See also:accumulation of old facts. In particular, with his See also:fellow-worker Auguste See also:Laurent (1807–1853), he did much to reform the methods of chemical formulation by insisting on the distinction between atoms, molecules and equivalents; and in his unitary See also:system, directly opposed to the dualistic doctrines of See also:Berzelius, he combined Dumas' substitution theory with the old radicle theory and greatly extended the notion of types of structure. His See also:chief See also:works were Precis de chimie organique (1844–1845), and Traite de chimie organique (1853–1856).
