Physical chemistry and chemical education · 1830–1895

Julius Lothar Meyer

Meyer began in medicine and became interested in physiological chemistry before building a career in chemical research and teaching. His 1864 textbook grouped elements using atomic weights and valence. A 1870 paper plotted atomic volume against atomic weight, giving a graphical demonstration of recurring physical properties. Like Mendeleev, he benefited from the clarification of atomic weights discussed at the 1860 Karlsruhe Congress.
