Alexander Just
Friedrich Alexander Just (born April 12, 1874 in Bremen , † May 30, 1937 in Budapest ) was a German - Hungarian chemist and inventor .
Life
His parents were Maximilian Alexander Just (born June 22, 1845 in Marienburg) and Elisabeth Dorothea Sophie Hoyerman. His uncle, the chemist Eduard Just , had a photo paper factory in Vienna .
The merchant family moved to Vienna in 1882 , where Alexander was enrolled at Mariahilf-Gymnasium two years later. In 1892 he began his studies at the University of Vienna and listened to chemistry, physics, philosophy, mathematics and mineralogy. At the suggestion of his uncle, he began his doctoral thesis in 1894 and was awarded his doctorate two years later. He worked as an assistant at the Department of Analytical Chemistry at the Technical University of Vienna.
In 1900 he married Anna Maria Elisabeth Nozsicska, with whom he had four sons and a daughter. At first the family lived in poor conditions on Gumpendorfer Strasse.
At the institute he met Franjo Hanaman , with whom he developed a process for the manufacture of tungsten filament, for which they received a patent in April 1903. Two lightbulbs that were tested at the Institute for Electrical Engineering proved to be economical with 1 W / HK. They were referred to Siemens & Halske, where development of the tantalum lamp had just begun so that the negotiations remained fruitless. They got the attention of Richard Engländer and Jozsef Pinter (uncle of Nicholas Kurti ).
When Hanaman went to Lédecz as a cement chemist in 1904, the Justs moved to Breslau, where Alexander found work at Egyesält Villamossági (from 1909 Tungsram ).
Newspaper reports in 1916 that he had invented a self-regenerating dry cell battery from atmospheric oxygen turned out to be a duck.
During the First World War he served as a medic and was released as an ensign in the reserve. In 1919 he received Hungarian citizenship.
