JULIUS LOTHAR See also:MEYER (183o-1895)  , See also:German chemist, was See also:born on, the 19th of See also:August 183o, at Varel in See also:Oldenburg . He was the son of a physician, and went to study See also:medicine first at See also:Zurich University in 1851, and then, two years later, at See also:Wurzburg, where he had R . See also:Virchow as his teacher in See also:pathology . The See also:influence of C . F . W . See also:Ludwig, under whom he studied at Zurich, decided him to devote his See also:attention to physiological See also:chemistry, and therefore he went, after his See also:graduation (1854), to See also:Heidelberg, where R . See also:Bunsen held the See also:chair of chemistry . There he was so influenced by G . R . See also:Kirchhoff's mathematical teaching that he took up the study of mathematical physics at Kiinigsberg under F . E .

Neumann . In 1859 he became privat-docent in physics and chemistry at See also:Breslau, where in the preceding See also:year he had graduated as Ph . D. with a thesis on the See also:action of See also:carbon monoxide on the See also:blood . In 1866 he accepted a See also:post in the School of Forestry at See also:Neustadt-See also:Eberswalde, but soon moved to Carlsruhe See also:Polytechnic . During the Franco-German See also:campaign the Poly-technic was used as a See also:hospital, and he took an active See also:part in the care of the wounded . Finally, in 1876, he became See also:professor of chemistry at See also:Tubingen, where he died on the rrth of See also:April 1895 . His name is best known for the See also:share he had in the periodic See also:classification of the elements . He noted, as did J . A . R . New-lands in See also:England, that if they are arranged in the See also:order of their atomic weights they fall into See also:groups in which similar chemical and See also:physical properties are repeated at periodic intervals; and in particular he showed that if the atomic weights are plotted as ordinates and the atomic volumes as abscissae, the See also:curve obtained presents a See also:series of See also:maxima and minima, the most electro-See also:positive elements appearing at the peaks of the curve in the order of their atomic weights . His See also:book on See also:Die modernen Theorien der Chemie, which was first published in Breslau in 1864, contains a discussion of relations between the atomic weights and the properties of the elements .

In 1882 he received from the Royal Society, at the same See also:

time as D . J . Mendeleeff, the See also:Davy See also:medal in recognition of his See also:work on the Periodic See also:Law . A younger See also:brother, O . E . See also:Meyer, became professor of physics at Breslau in 1864 .
