Now... There are a countless number of people that can be mentioned for their worth, and many will obviously be named over the few number of days. To start off, though, I think I'll have to nominate a guy whose memorial I have visited in Atlanta. That guy would be Dr. Martin Luther King, Jr.
I can fairly assume that everyone here would vouch for Dr. King for the World Hall of Fame. I managed to buy a Civil Rights book and a DVD on King himself. He was an extremely important part in the Civil Rights movement. I'd like to think that without him, the changes that have been made in this country would not exist today. I couldn't help getting a lump in the throat when looking at some of the stuff they offered at The King Center where the memorial sits. His speeches are extremely inspirational and wise. I think everyone should hear them at least once in their lifetime. There's a lot you can learn from him.
Well, that's my two cents. I'll add some more guys later once some other people start posting. Feel free to add more info about Martin Luther if you can.
