“Publication/disclosure” will be treated as “date granted”, for now. The “Megjelent (year). évi (month) hó (day)-én”, that is “Released (month) (day), (year)”, given on the original, is seemingly always later, and we do not know the which legally constitutes the patent's being “granted”. Fortunately, filing date data is clean and simple and consistent between the data page and the original.

Pierre Georges Albert Levasseur[1][2], born 16 July 1890 in Paris[3][4] and deceased 2 August 1941 in Paris[5][6][7][8].
