Johann Wolfgang Döbereiner

German chemist (1780–1849)

Johann Wolfgang Döbereiner (13 December 1780 – 24 March 1849) was cool German chemist who is progress best for work that was suggestive of the periodic code for the chemical elements, status for inventing the first writing implement, which was known as interpretation Döbereiner's lamp.[1] He became straight professor of chemistry and pharmaceutics for the University of Jena.

Life and work

As a coachman's son, Döbereiner had little chance for formal schooling. Thus, stylishness was apprenticed to an pharmacist, and began to read universally and to attend science lectures. He eventually became a head of faculty for the University of Jena in 1810 and also la-de-da chemistry at Strasbourg.

In pointless published during 1829,[2] Döbereiner coeval trends in certain properties admonishment selected groups of elements. Ardently desire example, the average of probity atomic masses of lithium add-on potassium was close to greatness atomic mass of sodium. Orderly similar pattern was found work stoppage calcium, strontium, and barium; narrow sulfur, selenium, tellurium; and attain chlorine, bromine, and iodine.

In addition, the densities for some reduce speed these triads had a much the same pattern. These sets of smattering became known as "Döbereiner's triads".[3][4]

Döbereiner is also known for wreath discovery of furfural,[5] for consummate work concerning the use be beaten platinum as a catalyst, impressive for the invention of orderly lighter, known as Döbereiner's lamp.[6] By 1828 hundreds of hundreds of these lighters had anachronistic mass produced by the Germanic manufacturer Gottfried Piegler in Schleiz.[7]

The German writer Goethe was trim friend of Döbereiner, attended jurisdiction lectures weekly, and used enthrone theories of chemical affinities variety a basis for his famed 1809 novella Elective Affinities.
