Bks I've read lately that relate to civil rights

Several of you have read books about people who have contributed to the civil rights of Americans. Some related books you might be interested in follow:
The Greatest (Walter Dean Myers) is about Muhammed Ali. I'm sure we all remember when he lit the torch in the Atlanta Olympics but what do you know about him and his contributions to civil rights for African Americans?

The Voice that Challenged a Nation (Russell Freedman) is about Marian Anderson who had one of the greatest voices of the 20th century. The problem was that she could not sing for integrated audiences and was banned from singing in Constitution Hall in Washington, D.C. The solution to the problem was that she would sing at the Lincoln Memorial--these events (and others that are too many to list) led to the opening of buildings to integrated audiences and to African American performers. Also read about Eleanor Roosevelt's response to the ban at Constitution Hall. All this happened not too long ago.

Young, Black, and Determined (Patricia McKissack & Fredrick McKissack) is about Lorraine Hansberry. Do you know who Lorraine Hansberry was and what she should be known for? You definitely need to read this book to learn about this fascinating African American woman.
Vision of Beauty (Kathryn Lasky) is a picturebook biography about Sarah Breedlove Walker--perhaps you know her as Madame C. J. Walker--or perhaps you have never heard of her--she was a millionaire--does that give you a clue?

Can you tell I like to read biographies? I am particularly intrigued by biographies about African Americans who were neglected in the history lessons I learned--most had made history when I was growing up, but still, they were not mentioned in our history books. This really troubles me that I know so little about American history.

I wonder who you can name off the top of your head that is/was an influential African American man or woman or child.
