You may read all about him at http://nobelprize.org/nobel_prizes/peace/laureates/1964/king-bio.html. Then google Martin Luther King for other articles.
I grew up in the South during some of the mess that you read about in the history books. I remember it somewhat and looking back on it now as an adult I see where things that happened were not right. None of us now can help what happened in the past but we sure can help what happens in the future.
To all of you that live in a foreign country and do not know about Dr. King, it is worth reading about and seeing the history of the Civil Rights Movement.
HAPPY DR. KING DAY!
