Lothar von Meyer, German Chemist

Julius Lothar von Meyer (August 19, 1830 - April 11, 1895) was a German chemist. After his graduation in 1854 he went to Heidelberg, where Robert Bunsen held the chair of chemistry. In 1859 he became privat-docent in physics and chemistry at Breslau. In 1860 he had graduated as Ph.D. with a thesis on the action of carbon monoxide on the blood. He is best known for the share he had in the periodic classification of the elements. His book on Die modernen Theorien der Chemie, published in 1864, has an early version of the periodic table containing 28 elements classified into 6 families by their valence. Mendeleev published his periodic table of all known elements in 1869. Working completely independently, a few months later, Meyer published a revised and expanded version of his 1864 table, virtually identical to that published by Mendeleev. In 1882, Meyer received from the Royal Society, at the same time as Mendeleev, the Davy Medal in recognition of his work on the Periodic Law. In 1876, Meyer became the first Professor of Chemistry at the University of Tubingen, where he served until his death. He died in 1895 at the age of 65.
