[General Time Travel] Which historical figure has the most time travelling vistors and how does the knowledge of becoming world famous for centuries/millennia affects that person?

by far, FAR, the most visited historical figure is Hitler. 

Countless amateur Time-Travellers go back to try to kill him, and are usually thwarted either by:

- time travelling Neonazis
- actual Nazis who dabble with super-science/occult and know how to stop a time traveller
- Time Cops that want to protect the timeline

The thing with visiting, let alone trying to kill historical figures is that it changes history greatly, splitting a branching timeline. For example, killing Hitler almost always results in Germany getting a new, smarter and more pragmatic villain for a leader, and WW2 gets much worse.

Interestingly, in timelines where Hitler meets time travellers and survives, he is not changed much. He already seems to consider himself a god-like being, and his enemies Untermench. Time-travelling anti-Nazi assassins only confirm his conviction.
