Johann Wolfgang Döbereiner (born Dec. 13, 1780, Hof an der Saale [Germany]—died March 24, 1849, Jena) was a German chemist whose observation of similarities among certain elements anticipated the development of the periodic system of elements.
Johann Wolfgang Döbereiner - Wikipedia
Johann Wolfgang Döbereiner (13 December 1780 – 24 March 1849) was a German chemist who is known best for work that was suggestive of the periodic law for the chemical elements, and for inventing the first lighter, which was known as the Döbereiner's lamp. [1] . He became a professor of chemistry and pharmacy for the University of Jena.

Johann Wolfgang Döbereiner - Oxford Reference
Döbereiner was interested in catalysis in general and discovered the catalytic action of manganese dioxide in the decomposition of potassium chlorate. His law of triads (1829), based on his observation of regular increments of atomic weight in elements with similar properties, was an important step on the way to Dmitri Mendeleev's periodic table.
