Miksa Déri – (b. 1854, d. 1938) Ottó Bláthy – (b. 1860,  d. 1939) Károly Zipernowsky – (b. 1853, d. 1942)

Their names are mentioned together by historiography. The great triad of Miksa Deri, Otto Titusz Blathy, and Karoly Zipernowsky (left to write) was connected by the invention of the transformer and worked at the famous Ganz factory in Budapest. In the 1880s scientists were often engaged in working on the distribution of electric light. Edison had solved the problem of carrying light economically to short distances with DC (direct current). Historical credit is due to Zipernowsky and his colleagues for developing the economical transmission and distribution of light to long distances. In 1889 they developed the transformer and the AC (alternate current) energy distribution system based on transformers connected in parallel shunt. The state of the art electric equipment they produced was admired by the trade all over the world and is and is part of our life until today. Other inventions by them include: the tension regulator, the wattmeter, the alternating current motor, the turbogenerator and the high efficiency turbogenerator, and the AC electric generator.
