Life

Werner Flechsig was born on June 8, 1900 in Cologne. He began studying mathematics and physics at the Technical University of Hanover and continued at the Georg-August University in Göttingen . He became an assistant to Robert Wichard Pohl and received his doctorate in 1925 with the dissertation “On the knowledge of the photoelectric primary current in crystals”, in which he also took into account the work of Pohl's assistant Bernhard Gudden . Then he dealt with hot cathodes and photocells .

Flechsig became an employee of the television company in Berlin, where he developed image pickup tubes . In 1936 he made the orthicon technique ready for practice, which was to replace the iconoscopes used at the Summer Olympics .

In 1937 a color television process with two basic colors was demonstrated by the Reichspost Research Institute at the radio exhibition , but it was not convincing, so that an additive color mixture with three basic colors to generate all colors was discussed as an alternative.

Flechsig invented the basic principle of producing colored pictures with color picture tubes and registered it in July 1938 as a German Reich patent with the title "Cathode ray tube for producing multicolored pictures on a fluorescent screen". The technical implementation of the shadow mask picture tubes was discontinued in 1940 due to the war, and the first commercial realization was done in 1949 by the Radio Corporation of America .

Flechsig was an honorary member of the Television and Cinema Technology Society .

Werner Flechsig died on October 12, 1981 in Wolfenbüttel.
