Johann von[1] Michelsohnen (also Mikhelson or Michelson; Russian: Ива́н Ива́нович Михельсо́н, romanized: Ivan Ivanovich Mikhelson; 14 May [O.S. 3 May] 1740 – 17 August [O.S. 5 August] 1807) was a Baltic German military commander who served in the Imperial Russian Army. He was a prominent general in several wars, but his most noted contribution was his critical role in suppressing Pugachev's Rebellion.
^In German personal names, von is a preposition which approximately means 'of' or 'from' and usually denotes some sort of nobility. While von (always lower case) is part of the family name or territorial designation, not a first or middle name, if the noble is referred to by his last name, use Schiller, Clausewitz or Goethe, not von Schiller, etc.
