Bláthy, Otto Titusz (Tata, 11 August 1860 - Budapest, 26 September 1939) – Mechanical engineer, inventor, well-known electro-technical pioneer. He studied at the Polytechnic of Vienna, worked with the MÁV (Magyar Államvasutak, Hungarian National Railways) Machine Works (1881-1883), and joined the Electrical Division, established in 1878, of the Ganz Works, Budapest. In the new work environment he recognized the practical application of Ohm’s Magnetic Law and with this knowledge designed his own machines, based on his own calculations, ahead of other countries. A list of results of some of his endeavors follows a patent on his Watt-meter in 1884: solution of the problem of parallel-connection of alternating-current generation in 1887, considered unsolvable before; the first induction Watt-meter (meters of power consumption) was adopted at the end of 1889; significant contribution to the development of the commutator motors in 1891; an automatic rotation-counter for water turbines in 1891; design of four-pole generators in 1903, followed by two-pole generators of gradually increasing performance; patent on a stroboscopic process for the certification of current meters; pioneering role in phase transformer of wide-gauge locomotives. He published about 50 articles in Hungarian and other languages. He was a gifted person who had outstanding abilities for langauges and mental arithmetics. As an author of complex chess problems, he published a book entitled Vielzügige Schachaufgaben in Leipzig in 1889. He was well ahead of his time. Most of his ideas are still timely. In the early 1800s the majority of experts in this field thought that the future belonged to direct current. Three engineers of the Ganz Industries of Budapest: Ottó Bláthy, Miksa (Maximilian) Déri and Károly (Charles) Zipernovsky envisioned the development of alternating current. As early as 1882, they built a generator-producing alternating current. At the Vienna Exhibition of 1883, the 150HP 54 V alternating current generator, feeding 1200 bulbs directly, was such a success that it brought about the adoption of alternating current worldwide. In 1884 he calculated and designed the first transformer together with Károly Zipernowsky (1853-1942) and Miksa Déri (1854-1938). They invented water turbines to generate electricity. The electrical system of the City of Rome was built according to their plan. A street in Budapest and a high school in Miskolc bear his name. – B: 0883, 1105, T: 7674, 7390.→Zipernowsky, Károly; Déri, Miksa.
