Elvis Presley

And let me place my own choice now, and I think I'll go for this one. Fun fact, he and I both have our birthday on June 19th (and I wonder if that is a coincidence or not), and I've learned a lot about coding when I coded in Pascal, which was named after him too. Somehow I feel some connection to him.

Remarkable choice... ;)

Michael Jackson

Alexander Sergeyevich Pushkin. He was a Russian poet in the 18th-19th century. Absolutely love the guy

Albert Einstein (not the smart part, but we basically have the same personality)

Heinz Gudarian ( ww2 German commander invented blitzkrieg and made the tank a eficcient killing machine

Remarkable choice.... But I guess he did make an important historical contribution to history, yes ;)

Yep

Or that Russian commander

Just as a note, the person in question had to be dead prior to your birth, otherwise you cannot be he/her re-incarnation. Plus whether this person is a man or a woman does not matter in your current gender, as it has never been stated a male cannot re-incarnate as a female or vice versa. Neither does country or skin color or whatever matter. As long as it's a historic person who died before you were born, it counts.... And it doesn't even matter if you agree with that person now.... (different times bring different opinions).

But do they have to have died before my birth? Because i really want to pick Stan Lee

Well, in theory you can only reincarnate after you die, right, so I deem it highly unlikely you can be the reincarnation of somebody who die when you were already born... That was a bit of the theory.
