If You Could Have Dinner with Anyone

If you could have dinner with anyone from the past, who would it be?

Dinner with any person from the past wouldn't work because you would spend all of the dinner explaining technology like your phone ringing in your pocket or vernacular like what the griddy is. In other words, by virtue of being a regular person from the future, you are by default more interesting to them than they are to you, just because your world is more interesting.

I think a better question is: who would you want to have dinner with from the future? What archetype would you like to have this person encapsulate? Scientist from 2900? Starving artist from 2356? Warmonger from 3790, when all war is done in an Ender's Game type format?
