Kálmán Tihanyi in England, 1930

Kálmán Tihanyi , in Hungarian Tihanyi Kálmán [ ˈtihɔ̃jɲ ˈkaːlmaːn ] (born April 28, 1897 in Üzbég , Neutra County ; † February 26, 1947 in Budapest ) was a Hungarian physicist and inventor . He improved the sensitivity of the cathode ray tube and in 1928 invented the radioscope, a complete electronic television system consisting of a camera, an image pickup tube (on the receiving side similar to the iconoscope ) and a television set.

Tihanyi worked in London for the UK Aviation Department in the 1930s . He returned to Hungary in 1940 after the outbreak of World War II, but before Hungary entered the war. As a supporter of the politician Endre Bajcsy-Zsilinszky , he was temporarily arrested in 1941 for propaganda activities against the National Socialist German-Hungarians. After the German occupation of Hungary in March 1944, he was imprisoned by the German SS for five months. When the Germans installed the Szálasi regime of the Arrow Cross in October 1944 , he went underground.
