Oskar Frölich

Emil Adolf Oskar Frölich (born November 23, 1843 in Bern , † July 6, 1909 in Berlin ) was a technician who worked in Berlin in the fields of electrical engineering, telegraphy, electrochemistry and solar heat.

In 1868 he wrote his dissertation on the influence of the absorption of solar heat in the atmosphere on the temperature of the earth at the Albertus University in Königsberg . In 1873 he was employed by Siemens as the first physicist to investigate magnetism. In 1881, based on the theory he had developed in 1871, he constructed a spherical electrodynamometer in which the fixed and movable roles of Weber's instrument were replaced by wound spherical surfaces. Almost at the same time, Friedrich Kohlrausch built a similar instrument.
