Paul Hatschek

Paul Hatschek (* 11. March 1888 Troppau ; † 15. May 1944 in Brandenburg-Gorden ) was a Czech-German doctorate in engineering for optics and film technology and inventor . Hatschek was a resistance fighter against National Socialism .

Life

In 1926 he applied for a patent for a projection apparatus in Canada. The American patent "Optical projection apparatus" followed in 1928.

Since 1931 he published specialist publications in Germany, which particularly concerned the technology of the sound film .

In 1934 it was first mentioned in the Berlin address book. From 1935 he lived in a small apartment at Holsteinische Strasse 21 in Berlin-Wilmersdorf . The 1936 Olympic Games he pursued apparently still without dissident thoughts. He later joined the European Union resistance group, founded in 1939 by Robert Havemann and Georg Groscurth , and tried to pass information on to the Soviet Union .

The historian Bernd Florath writes: “The Czechoslovak citizen Hatschek was an engineer for optics and film technology. His investigations and inventions dealt primarily with sound film technology. He worked u. a. worked with Manfred von Ardenne and Hugh John Gramatzki , a correspondent for Albert Einstein , and published a number of books that were reprinted and translated after his murder. In Prague in 1937 he had offered the Soviet Union some inventions and was then recruited as a contact person for the GRU . Hatschek worked as a patent engineer for the Tobis film company in Berlin . He was connected to the Uhrig group and was therefore briefly arrested in the spring of 1942, but quickly released. "

In September 1943 he was born together with his wife Elli Hatschek , b. Lotz, (born July 2, 1901 in Wetzlar) arrested again. The People's Court sentenced him on March 27, 1944 together with his daughter, the secretary Krista Lavíčková , b. Hatschek (born December 15, 1917), on death. Hatschek was executed on May 15, 1944 in the Brandenburg penitentiary . On November 4, 1944, the People's Court also sentenced Elli Hatschek to death for her ties to the European Union and “degradation of military strength”. The verdict is from Dr. Signed by Erich Schlemann. She was executed on December 8, 1944 in Plötzensee , her daughter on December 11.
