The success story of today’s international Goldschmidt Group begins in 1895 with the invention of the thermite process by the chemist and pioneer of the railroad, Professor Hans Goldschmidt. He had succeeded in making the reduction of metal oxides with aluminum powder technically applicable.
Hans Goldschmidt (1861-1923) is the second son of Theodor Goldschmidt and Johanna Sophie Luise Goldschmidt (born Koner). He went to high school in Altenburg and studied chemistry from 1882, first in Berlin and then, like his older brother Karl Goldschmidt, at the University of Heidelberg, where he received his doctorate in 1886. After completing his doctorate, he took over the management of the father’s company “Chemische Fabrik Th. Goldschmidt”. The thermite process he developed in 1895, which made it possible to easily produce carbon-free metals such as iron, chromium and manganese, is still considered a standard procedure for welding railway and tram rails that is unsurpassed in quality worldwide.
Theodor Goldschmidt establishes the “Chemische Fabrik Th. Goldschmidt” in Berlin, Germany. Initially, the factory mainly supplied preliminary products for textile processing, including preparation salt, dextrin, chlorinated lime, tin salt and chlorine tin. The main customer was the Kattun printing company R. Goldschmidt & Sons, relatives of Theodor Goldschmidt.
The company founder Theodor Goldschmidt passes away.
After receiving his PhD in chemistry Karl Goldschmidt takes on sole management responsibility for the time being of the Chemische Fabrik Th. Goldschmidt company.
For about 30 years the brothers Karl and Hans Goldschmidt share responsibility for the company – Karl Goldschmidt as entrepreneur and politician with a social conscience and Hans Goldschmidt as a chemist who promotes technical development.
