Johann Wolfgang Döbereiner
Johann Wolfgang Döbereiner (13 December 1780 – 24 March 1849) was a German chemist who is best known for work that foreshadowed the periodic law for the chemical elements, and for inventing the first lighter, which was known as the Döbereiner's lamp. He became a professor of chemistry and pharmacy at the University of Jena. Life and work As a coachman's son, Döbereiner had little opportunity for formal schooling. Thus, he was apprenticed to an apothecary, and began to read widely and to attend science lectures. He eventually became a professor at the University of Jena in 1810 and also studied chemistry at Strasbourg. In work published in 1829, Döbereiner reported trends in certain properties of selected groups of elements. For example, the average of the atomic masses of lithium and potassium was close to the atomic mass of sodium. A similar pattern was found with calcium, strontium, and barium; with sulfur, selenium, tellurium; and with chlorine, bromine, and iodine. ...
