Hans Goldschmidt

Born 18 Jan 1861; died 25 May 1923 at age 62.German chemist who invented the thermite (alumino-thermic) process which was adopted worldwide for welding railroad and streetcar rails, and is still in use for on-site welding. The first track so welded was laid in Essen. This method evolved from his Goldschmidt reduction process that he began investigating in 1893 for the preparation of carbon-free metals. He used the reactions of oxides of certain metals with aluminum to yield aluminum oxide and the free metal. It has been applied to separate chromium, manganese, and cobalt from their oxide ores. Goldschmidt was also a co-inventor of sodium amalgam. His father, Theodor Goldschmidt, founded Chemische Fabrik Th. Goldschmidt which became the modern company, Degussa.«
