Fritz Blau

from Wikipedia, the free encyclopedia

Fritz Blau (born April 5, 1865 in Vienna , † December 5, 1929 in Berlin ) was a chemist and senior scientist at the Osram Group.

His parents were the change agent Josef Blau, Jr. (* 1833 in Budapest - 1905) and Johanna, geb. Taussig (* 1837 in Trebitsch, Moravia - 1912).

Fritz Blau studied chemistry at the University of Vienna , earned his doctorate in 1886 and then worked as Robert von Lieben's laboratory assistant . He spent a year in Adolf von Baeyer's laboratory . In 1902 he was hired by the Auer Society in Berlin. Around 1903 he worked at the electrical incandescent lamp factory "Watt" AG (originally Scharf & Co. , from 1900 Siemens), where he applied for a patent for a "process for the manufacture and repair of electric incandescent lamps". As a result of a patent dispute, he moved to the litigation opponent Deutsche Gasglühlicht AG , where he developed the Osram brand.

As early as 1906, he pointed out the decisive influence that the surface quality of a filament can exert on its emissivity. The rougher a thread surface is, the more cavities it has, the “black” it will behave under otherwise identical circumstances.

He received over 180 other patents. His successor was Karl Mey .
