Madame CJ Walker (1867-1919), born Sarah Breedlove McWilliams Walker,
is generally credited with being the first Black woman to become a
millionare and the first self-made female millionare in the United
States , around 1910. It is not clear whether this honor belongs to
Annie Turbo Malone. Both women became rich producing hair care
products with Walker credited with inventing the modern hot comb.
