Dobereiner, Johann Wolfgang (1780-1849), a German chemist. He discovered furfural, an oily liquid used in making synthetic rubber, in refining gasoline, and as a bleaching agent. His discovery of the catalytic action of platinum led to his invention of the Dobereiner lamp, a fire-starting device widely used before the invention of matches. It consists of finely divided platinum whose catalytic action ignites a jet of hydrogen gas that is passed over it. Dobereiner also did early work in grouping chemical elements by triads (threes), a step in the development of the Periodic Table. Dbereiner was born in Bavaria. He was professor of chemistry and pharmacy at the University of Jena after 1810.
The man who had some theories about relativity was also an eccentric who gleefully eschewed socks, dodged German military service and spurned social conventions.
He's ventured to the abyss of black holes, wagered on the information paradox and floated around in zero gravity. Meet the man, the legend, the super scientist: Stephen Hawking.
