Heinrich Schallbroch

Heinrich Emil Karl Schallbroch (born July 4, 1897 in Huckingen ; † September 2, 1978 in Munich ) was a German mechanical engineer and professor of machine tools .

Life

He was the son of the businessman Heinrich Schallbroch and his wife Hedwig, nee Mittmann. From 1903 to 1907 he attended the primary school in Huckingen and then until 1915 the municipal high school in Duisburg, where he passed his Abitur in 1915.

In the same year he enlisted during the First World War as a volunteer for the Bavarian army . From August 1915 was with the II. Replacement Department of the 12th Field Artillery Regiment . There he was promoted to private , and later to non-commissioned officer. In 1917 he took part in fighting on the Eastern Front a . a. in what is now Belarus . For his work, Schallbroch received the Military Merit Cross III on July 20, 1917 . Class with crown and swords; two months later (September 13, 1917) the Prussian Iron Cross 2nd class. In 1918, Schallbroch took part in fighting on the Western Front in Lorraine . There he was injured in 1918 and went through various hospitals . On December 15, 1918, he was released from the club hospital in Huckingen as a lieutenant in the reserve .

At the beginning of 1919, he completed a six-month internship at the Mannesmannröhren-Werke in Huckingen. In the summer of 1919 he went to MAN in Nuremberg for three months . From the winter semester of 1919/20 he studied mechanical engineering at RWTH Aachen University , where he passed his diploma examination in May 1923. In the same year he became an employee of Schiess AG in Düsseldorf , for which he worked for two years.

From July 1925 he worked for Adolf Wallichs' chair at RWTH Aachen University . The first few months as an assistant, from November 1925 to 1934 as chief engineer at the chair and laboratory for machine tools and industrial engineering. In 1930 he received his doctorate in engineering. with the topic " Investigations into the sinking and rubbing of iron, copper and aluminum alloys. " Almost three years later he submitted his habilitation thesis on " The machinability of metals with special consideration of the materials used in mechanical engineering ". Schallbroch gave his habilitation lecture on the drilling properties of cast iron and steel on July 1, 1933. Shortly afterwards, he was appointed private lecturer for workshop operations and manufacturing processes . In April 1934 he was offered a chair for mechanical technology at the Technical University of Munich . After the death of Christian Prinz in 1934, he took on the role of full professor of the Institute for Machine Tools and Industrial Management (iwb). He headed the institute until 1945.

After the war, almost all of the department staff were dismissed by the military government. This explained to the chair that he was "?? permitted to produce and test but not to do research ??" . Schallbroch then oriented himself to Berlin. At the Technical University of Berlin , he took over from Karl P. Matthes as head of the chair for machine tools and production technology and thus also the institute for machine tools and factory operations (IWF). He headed the institute until 1965. His successor was Günter Spur .

Schallbroch was married three times. Shortly after completing his studies, he married Elisabeth ( Else ) Stühlen (* 1900) on June 12, 1923 . His two children came from this marriage: Martha, born on August 27, 1924, and Werner, born on November 1, 1930. In 1949 he married Maria Schwertfirm, in 1963 Gertraud Engl.
