Life

At Easter 1913 he obtained his secondary school leaving certificate at the Friedrich-Wilhelm-Gymnasium in Cottbus . He then began studying chemistry at the Friedrich-Wilhelms-Universität Berlin and worked in the I. Chemical Institute headed by Emil Fischer . With the outbreak of the First World War in 1914, he joined the 1st Guard Dragons (cavalry regiment) as a war volunteer. He was used as a cavalryman, artilleryman and since 1916 as an infantryman in various regiments in various theaters of war. In 1917 he was promoted to lieutenant in the reserve. He passed the association examination before the war and during a vacation in December 1917. In December 1918 he was released from military service.

He resumed his studies in Berlin in February 1919 and received his doctorate from Burckhardt Helferich in July 1920 with a thesis on γ-phenyl-γ-oxy-n-butyraldehyde .

At the beginning of the 1920s he founded the Lausitz industrial laboratory at Wernerstraße 25 in Cottbus as a public chemical research institute. It was a special laboratory for glass production and ceramics, examination of glasses and glazes. He also advised companies on manufacturing defects of all kinds, testing raw materials and finished products.

Among other things, he developed an extract from spruce needles as a therapeutic agent , the Daroliko bath . At the end of the 1920s he went to the Soviet Union (Moscow, Leningrad, etc.) every three months , where he contributed to the development of the brick industry as a building materials chemist.

At the beginning of the 1930s, Lecher founded the Lausitz Dental Depot .

From the 1920s onwards, Lecher's major scientific contributions were in the chemistry of ceramics and glass production. His work received international attention.

In 1934 Oskar Lecher was involved in securing the Cottbus gold discovery .

For many years he was a member of the Kreutzer department of the German Sailing Association and the author of various articles in the magazine "Yacht". In February 1941, he passed the maritime skipper examination at the Stettin seafaring school.

In November 1944, he commissioned two French prisoners of war, the architect André Malizard (architect of the Swedish embassy building in Paris 1972-74) and the interior designer Roland Malassinet (Ecole Nationale Supérieure des Arts Décoratifs) to plan a country house on a 5,000 m² water plot at Schwielochsee.

After the end of the war, he was arrested on June 23, 1945 by the operational group of the NKVD of the USSR in Cottbus (inmate number 27,800) and taken to special camp No. 6 Jamlitz near Lieberose. The arrest charge on July 21, 1945 was of being a member of the werewolf underground movement . On May 4, 1947, he was transported from special camp No. 6 to NKVD special camp No. 1 in Mühlberg , where he died of tuberculosis on October 30, 1947 in the hospital (zone 5) .

His wife Johanna Lecher continued to run the Lusatian dental depot after his death . The Lausitz industrial laboratory Dr. Oskar Lecher even existed until 1952.

An application to the General Prosecutor's Office of the Russian Federation for rehabilitation in 2000 was rejected as follows: Since Mr. Lecher was not prosecuted for charges of acts against citizens or interests of the USSR, but was interned, the law of the Russian Federation of 18.10 .91 "On Rehabilitation of Victims of Political Repression" cannot be applied to his case.
