Johann Georg Halske
Johann Georg Halske (* July 30, 1814 in Hamburg, † March 18, 1890 in Berlin) was a German entrepreneur.
Halske was the son of sugar broker and volunteer city council Johann Heinrich Halske. From 1825 to 1828 he was a student at Berlin High School to the Grey Abbey.
In 1828 he left school and went for a short time at the Berlin machine builders Schneggenburger in the Knights Road 37 in the teaching and then moved to the workshop of precision mechanic Wilhelm Hirschmann. After his apprenticeship he worked in various companies in the precision engineering, most recently at the famous Hamburg mechanic Repsold.
In 1843 he returned to Berlin, where he founded in 1844 together with the mechanic Frederick M. Boetticher in the Charles Street a workshop for the construction of chemical and mechanical appliances. Developed for the physiologist Du Bois -Reymond and he built electro-medical devices such as slide inducers.
The directory of members which was founded in 1845 Physical Society of Berlin, which later became the German Physical Society, we find the name of the mechanic JG Halske alongside well-known names like Hermann Helmholtz, Emil H. du Bois -Reymond, Rudolf Virchow and Werner Siemens. Halske and Siemens met during the meetings and symposia of the society in the house of the physicist Heinrich Gustav Magnus, the Magnus house Kupfergraben understand (which was acquired in 2001 by Siemens AG and asked the German Physical Society available again ).
1846, Siemens presented with 'his' pointer telegraph in Halske & Boetticher ago. Halske broke up the following year by his Compagnon and devoted himself to the construction of the Siemens'schen telegraph. On October 12, 1847 he founded together with Werner Siemens, the Telegraph Construction of 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 and the adoption financially risky major contracts for the laying of telegraph cables caused him concern. In addition, its traditional workshop organization contradicted an economic optimization of production and division of labor by cheaper methods, which led to tensions with the London business. 1867 Halske withdrew due to disagreements with the Siemens brothers from the firm and devoted himself as Berlin city councilor to the administration of the city and the establishment of the Museum of Decorative Arts ( 1867, he was elected to its Board of Directors and in 1881 as its second vice-chairman ). With Werner von Siemens remained friends until his death.
Johann Georg Halske became involved after leaving the company he co-founded, for example through its financial contribution to the 1872 founded Siemens pension fund.
Halske had married Henriette Friederike Schmidt in 1846. From this marriage two sons and two daughters were born. Johann Georg Halske, was buried in the family vault in the Trinity Cemetery II in field M G3. His grave stone with a portrait medallion of Julius Moser has been preserved.
