Kálmán Tihanyi (28 April 1897, Zbehy (Üzbég) – 26 February 1947, Budapest), was a Hungarian physicist, electrical engineer and inventor. One of the early pioneers of electronic television, he made significant contributions to the development of cathode ray tubes (CRTs), which were bought and further developed by the Radio Corporation of America (later RCA), and German companies Loewe and Fernseh AG. He invented and designed the world's first automatic pilotless aircraft in Great Britain.
Born in Üzbég, Kingdom of Hungary (since 1920 Zbehy, Slovakia), Tihanyi studied electrical engineering and physics in Preßburg (today Bratislava) and Budapest.
Tihanyi called his fully electronic television system "Radioskop". His patent application contained 42 pages detailing its design and mass production. It is recorded in UNESCO's Memory of the World Programme. Though it bears certain similarities to earlier proposals employing a cathode ray tube (CRT) for both transmitter and receiver, Tihanyi's system represented a radical departure. Like the final, improved version Tihanyi would patent in 1928, it embodied an entirely new concept in design and operation, building upon a technology that would become known as the "storage principle". This technology involves the maintenance of photoemission from the light-sensitive layer of the detector tube between scans. By this means, accumulation of charges would take place and the "latent electric picture" would be stored. Tihanyi filed two separate patent applications in 1928 then extended patent protection beyond Germany, filing in France, the United Kingdom, the United States, and elsewhere.
