From Inventing aviation

  • Inventor location: Marosvásárhely, location of Kornél Donner is currently located in Transylvania, Romania. Likewise is the case of Maroshévíz, the location of Béla Molnár. Both locations have changed national hands, and some of this tumult occurred in the early Twentieth Century. Name changesand name variations, between the Hungarian and Romanian languages, have occurred in the cases of each location. Both inventor names seem to be Hungarian. The names have been "half-Westernized" in that we are placing given names first, followed by family names. These may be cases in which AH is handy. Both locations are nationally designated as "(XX)" within the Hungarian database, which seems to be the protocol in cases of subsequently altered national status.
  • Donner occupation: iparfelügyelő, industrial supervisor or inspector?
  • Molnár occupation: főművezető, foreman or chief engineer?
