Otto Feussner

from Wikipedia, the free encyclopedia

Otto Feussner (born August 12, 1890 in Berlin , † July 25, 1934 in Hanau ) was a German physicist.

His father was Karl Feussner .

Studied in Marburg, a. a. at FF Martens.

For its research program he had Wilhelm Heinrich Heraeus to January 1, 1927 a new, independent department, the Metallurgical Laboratory set up, specifically the exploration of new precious metals - alloys served.

He developed a mechanically controlled spark generator as a light source for spectral analysis. He introduced a rotating interrupter into the discharge circuit of a spark generator, in which a capacitor is discharged via the analysis spark gap .

In 1933 he developed the first alloy of iridium with ruthenium for thermocouples .

He died on July 25, 1934 a few days after a fire in the high-frequency system as a result of inhaled toxic fumes.
