Here is someone to add to the list Victor Hugo Green The Negro Motorist Green Book.1947 it was for safe travel for black Americans in this time!
I think we need to look back at history and realize how the amazing inventions black Americans have given to the world this is why I say out of something horrifyingly bad came some great people! Honest Abe knew thing or two he was step ahead of people I feel if he was not shot he would have changed this country even more for the good.
