Mihály Csíkszentmihályi has died
The correct name is Mihály Csíkszentmihályi (never mind the diacritics, but the "i" appended to the first name is definitely wrong).Explanation for language nerds: Mihály is the Hungarian version of "Michael", Csíkszentmihály is a Hungarian village in Romania with a name derived from St. Michael (https://ro.wikipedia.org/wiki/Mih%C4%83ileni,_Harghita), and the "i" at the end denotes a toponymic surname (https://en.wikipedia.org/wiki/Toponymic_surname).
