Georg Hummel
Georg Hummel (born December 1, 1856 in Moosburg an der Isar , † March 12, 1902 in Munich ) was a German inventor and entrepreneur .
Life
His parents were the city pharmacist Georg Hummel (* 1818) and Ursula, geb. Satzenhofer (1827-1905). After completing his studies at the Technical University of Munich in 1882, Hummel started working for Sigmund Schuckert's company in Nuremberg. As head of the laboratory there, he developed and improved DC machines and dealt with materials testing. He developed and improved various instruments for measuring direct and alternating current and voltage. For a constructed with only a small proportion of iron moving iron instrument he received in 1884 the patent DRP 30 486. The patent DRP 43487 was granted in 1887 for improved electricity meter. After the international electrotechnical exhibition in Frankfurt in 1891, this patent was transferred to the British Thomson-Houston company , which developed the Thomson counter from it .
In 1893 he founded a meter factory in Munich. In 1895 he received the patent DRP 98 897 for the Hummel circuit that was later named after him . He is thus considered the inventor of the electricity meter.
Since 2009, the VDE has been awarding the Georg Hummel Prize , which is excellent study and final theses in the field of measurement of electrical energy and power, in particular in the areas of counting, measuring, testing, measurement data processing / transfer, the use of measurement technology to increase energy efficiency and related Topics from economic, social or legal disciplines.
