Michael Seidner

* Rimóc, February 1, 1875 – † Budapest, July 12, 1968 / electrical engineer, corresponding member of the Hungarian Academy of Sciences (1960) ; ; He completed his secondary education at the state high school in Losonc. He was a diligent solver of mathematical problems published by Kömal92, and in 1894 he won the first Student Competition of the Mathematical and Physical Society. He was a student at the Budapest and then the Berlin-Charlottenburg Technical University and received his doctorate in Germany. From 1903 he worked in the experimental laboratory of the Ganz Electricity Co. in Budapest, and later in the power plant design department. During the Soviet Republic of 1919, he was a production commissar, which is why he emigrated to Czechoslovakia, where he designed and technically managed several power plants in the Transcarpathian region (Beregszász, Munkács, Nagyszőllős, Tőketerebes, Ungvár). He returned to Hungary in 1928. His invention related to the liquid cooling of electrical machines is one of his most significant engineering achievements. He developed a new structure for the application of the liquid cooling system to turbogenerators. He supervised the construction of the Tiszaluc hydroelectric power plant. In 1959, he received the Kossuth Prize, and in 1960 he was elected a corresponding member of the Hungarian Academy of Sciences. ; ; His main works: ; The relationship between the general transformer circuit and voltage vector diagram, 1904, ; The development of liquid-cooled turbogenerators, 1961.
