Ferdinand Bernauer
Ferdinand Bernauer (born July 23, 1892 in Menzingen (Baden) , † May 16, 1945 in Berlin ) was a German mineralogist, geologist and developer of large-area polarization filters made from herapathite .
life and work
Bernauer was born as the son of the married couple Hermann Bernauer and Lina Dörschuck. His father worked as a senior teacher. After studying in Heidelberg, he joined the Geological State Institute in Berlin in early 1919.
Ferdinand Bernauer received an extraordinary professorship for mineralogy and petrography at the Technical University of Berlin in 1928 .
From 1930 he worked as a volcanologist . Related study trips took him to Iceland and Vulcano .
In 1938, the Technical University of Berlin transferred the management of the scientific deposit archive to Bernauer.
He also gained fame through the development of large-area monocrystalline polarization filters made of Herapathite , which were manufactured by the Zeiss company from 1935 and initially sold under the name "Herapathite Filter", but then from 1936 onwards under the name "Bernotar" based on his family name were. With the method developed by Bernauer, large-area, but only a fraction of a millimeter thick, single crystals of herapathite could be grown. These single crystals were mounted between two glass plates for optical use.
A war-related injury from shrapnel resulted in his death.
In 1919/20 he was at the Prussian Geological State Institute (PGLA).
