Johann Georg Halske
Johann Georg Halske (born July 30, 1814 in Hamburg , † March 18, 1890 in Berlin ) was a German entrepreneur .
Halske was the son of the sugar broker and honorary city councilor Johann Heinrich Halske. From 1825 to 1828 he was a student at the Berlin Gymnasium zum Grauen Kloster .
In 1828 he left school, for a short time did an apprenticeship with the Berlin mechanical engineering company Schneggenburger at Ritterstraße 37 and then switched to the workshop of the precision mechanic Wilhelm Hirschmann. After his apprenticeship, he worked in various precision engineering companies , most recently with the well-known Hamburg mechanic Repsold .
In 1843 he returned to Berlin and founded a workshop for the construction of chemical and mechanical apparatus there in 1844 together with the mechanic Friedrich M. Boetticher in Karlstrasse. For the physiologist Emil Heinrich du Bois-Reymond he developed and built electromedical devices such as sled inductors.
In the directory of members of the Physikalische Gesellschaft von Berlin , founded in 1845, later the German Physical Society , the name of the mechanic JG Halske can be found alongside well-known names such as Hermann Helmholtz , Emil H. du Bois-Reymond, Rudolf Virchow and Werner von Siemens . Halske and Siemens may have met at the Society's meetings and colloquia in the house of physicist Heinrich Gustav Magnus , the Magnus House on Kupfergraben (which was taken over by Siemens AG in 2001 and made available again to the German Physical Society).
In 1846 Siemens presented itself to Halske & Boetticher with 'his' pointer telegraph . In the following year, Halske broke away from his companion and devoted himself entirely to the construction of Siemens' telegraphs. On October 12, 1847, he and Werner Siemens founded the Telegraphen-Bauanstalt von Siemens & Halske in Berlin. For twenty years he headed the internal organization of the Berlin factory.
The international expansion of the company through the branches in St. Petersburg and London as well as the acceptance of financially risky large contracts for the laying of telegraph cables worried him. In addition, his traditional workshop organization contradicted an economic optimization of production through cheaper and labor-sharing methods, which led to tensions with the London business. In 1867 Halske withdrew from the company due to differences of opinion with the Siemens brothers and, as a city councilor of Berlin, devoted himself to the administration of the city and the development of the arts and crafts museum (in 1867 he was elected to its board of directors and in 1881 as its second deputy chairman). Halske remained on friendly terms with Werner von Siemens until his death.
Even after his departure, Johann Georg Halske was committed to the company he co-founded, for example through his financial stake in the Siemens pension fund founded in 1872 .
Halske had married Henriette Friederike Schmidt in 1846. This marriage resulted in two sons and two daughters. Johann Georg Halske was buried in the family's hereditary funeral on Dreifaltigkeitskirchhof II in field M, G3. His gravestone with a portrait medallion by Julius Moser has been preserved.
