Babi, Madame Walker became the first woman millionaire. A black, she started a black cosmetic line. I remember seeing something about her years ago, I think, in connection with an article or program on the founder of Ebony magazine, or on black entrepreneurs in general. Like I said, years ago so it's a bit fuzzy. I hadn't remembered her name, but I remember her accomplishment. Like you, I am totally unaware of some of the women profiled. The book title may be something of a misnomer, I think. Part of the Amazon book description reads: "With this collection of biographies, the author seeks to inform and inspire readers. We read so much about the Founding Fathers, but far less material has been made available to introduce the ladies, smart and strong in their own right, who have helped to form the political as well as the social universe that we are proud to call America."
I may see if I can get this at the library. But, like you, I am not so sure I want to pay money for it just now. If anyone has read it, I'd like an opinion.
