Johann Wilhelm Goldschmidt
Inventor of Thermite Welding
Johann Wilhelm Goldschmidt was born 18 Jan. 1861 in Berlin and Died 25 May 1923 in Baden-Baden Germany. A chemist who invented the aluminum-thermic for reducing oxides by using aluminum to produce aluminum-oxide and free-metal and is also known as the Goldschmidt reduction process. Using the same process within a sand mold, molten metal could be obtained from the exothermic reaction of aluminum and used to weld high carbon metals such as railroad rails.
