Everything about Johann Wolfgang D Bereiner totally explained
Johann Wolfgang Döbereiner (
December 13,
1780 –
March 24,
1849) was a
German chemist who is best known for work that foreshadowed the
periodic law for the
chemical elements.
Life and work
As a coachman's son, Döbereiner had little opportunity for formal schooling, and so he was apprenticed to an apothecary, reading widely and attending science lectures. He eventually became a professor at the University of
Jena in
1810. In work beginning in 1817, Döbereiner discovered trends in certain properties of selected groups of elements. For example, the average atomic mass of lithium and potassium was close to the atomic mass of sodium. A similar pattern was found with calcium, strontium, and barium, with sulphur, selenium, and tellurium, and also with chlorine, bromine, and iodine. Moreover, the densities for some of these triads followed a similar pattern. These sets of elements became known as "Döbereiner's triads".
Döbereiner also is known for his discovery of
furfural, for his work on the use of
platinum as a catalyst, and for a lighter, known as
Döbereiner's lamp.
The German writer
Goethe was a friend of Döbereiner, attended his lectures weekly, and used his theories of
chemical affinities as a basis for his famous 1809 novella
Elective Affinities.
