BERGMAN (1735-1784)  , See also:Swedish chemist and naturalist, was See also:born at Katrineberg, Vestergotland, See also:Sweden, on the loth of See also:March 1735 . At the See also:age of seventeen he entered the university of See also:Upsala . His See also:father wished him to read either See also:law or divinity, while he himself was anxious to study See also:mathematics and natural See also:science; in the effort to please both himself and his father he overworked himself and injured his See also:health . During a See also:period of enforced See also:abstinence from study, he amussd himself with See also:field See also:botany and See also:entomology, to such See also:good purpose that he was able to send See also:Linnaeus specimens of several new kinds of See also:insects, and in 1756 he succeeded in proving that, contrary to the See also:opinion of that naturalist, Coccus aquatic us was really the ovum of a See also:kind of See also:leech . In 1758, having returned to Upsala, he graduated there, and soon afterwards began to See also:teach mathematics and physics at the university, See also:publishing papers on the See also:rainbow, the See also:aurora, the pyroelectric phenomena of See also:tourmaline, &c . In 1767 Johann Gottschalck Wallerius (1709—1785) having resigned the See also:chair of See also:chemistry and See also:mineralogy, See also:Bergman deter-See also:mined to become a See also:candidate, though he had paid no particular See also:attention to chemistry . As See also:evidence of his attainments he produced a memoir on the manufacture of See also:alum, but his pre-tensions were strongly opposed, and it was only through the See also:influence of Gustavus III., then See also:crown See also:prince and See also:chancellor of the university, that he gained the See also:appointment, which he held till the end of his See also:life . He died at Medevi on See also:Lake See also:Vetter on the 8th of See also:July 1784 . Bergman's most important chemical See also:paper is his See also:Essay on Elective Attractions (1775), a study of chemical See also:affinity . In methods of chemical See also:analysis, both by the See also:blowpipe and in the wet way, he effected many improvements, and he made considerable contributions to mineralogical and See also:geological chemistry, and to See also:crystallography . He also made observations of the transit of See also:Venus in 1761, and published a See also:Physical Description of the See also:Earth in 1766 . His See also:works were collected and printed in 6 vols. as Opuscula Physica et Chemica in 1779-1790, and were translated into See also:French, See also:German and See also:English .
