Ida Bell Wells-Barnett (July 1862-March 1931) really lived a life. She was a teacher, and a journalist, most known for her work on documenting lynchings, and she was active in the civil rights and women's rights movements. Her parents were slaves, freed at the end of the Civil War. She wrote books, and books have been written about her. Wells' life and her work are fascinating. If you don't know much about her, take a couple minutes and read up. I'd suggest going here, here and here to start.
"Brave men do not gather by thousands to torture
and murder a single individual,
so gagged and bound he cannot make
even feeble resistance or defense."
-- Ida B. Wells
