Dr. Carl Auer von Welsbach, born on September 1, 1858 in Vienna, was an Austrian chemist and entrepreneur.
He discovered four elements and invented the gas-incandescent light, the metal filament lightbulb and the Cereisen flint for lighters.
His main scientific work was the rare earth elements and radioactive substances.
Companies such as AUERGESELLSCHAFT Berlin, Treibacher Industrie AG, OSRAM and others. were founded by him.
He made the first sound recordings with a phonograph in Austria (1900), was Austria's first color photographer (1908) and left us unique documents of his time.

|First disassembly of the supposed element "Didym" with the help of a new separation method developed by him and thus the discovery of the new elements praseodymium and neodymium.
Preparation of the first gaseous glow bodies of lanthanum oxide, with which it wraps the gas flame reticulated.
|Acquisition of the chemical-pharmaceutical factory Würth & Co in Atzgersdorf near Vienna for the industrial production of incandescent mantles.
|Beginning sales problems due to the shortcomings of the early incandescent mantles, closing the factory in Atzgersdorf. Beginning of the improvement of mantles by his further research.
|Development of the paste process for the production of filaments of refractory metals.
|Patenting of a new, improved incandescent body of 99% thorium oxide and 1% cerium oxide, resumption of production in Atzgersdorf and rapid spread of the incandescent body due to the increased luminosity and improved durability.

|August 4, 1929
|Carl Auer von Welsbach dies in his 71st year and is laid to rest in Vienna at the Hietzing Cemetery in the family grave.
