This question is a bit odd. Had it been Fictional person, I'd readily choose a few. But historical is a bit of a challenge. In as much as having Shakespeare and the like might seem interesting to have in a game, I don't really find that as fascinating as say having River Song or the kids from Stranger Things in a gaming group I'm in. The word historical also suggests it has to be someone from way back, so that removes wanting people like David Bowie or Vin Diesel in a game with us.
Given the need to choose one, therefore, I might be bland and just choose Jacob and Wilhelm Grimm, the German academic/linguist authors who collected and published folklore. I would love to have them in a game using Changeling the Lost and watch them freak out as the monsters they face are born from the stories they have gathered through the years.
