Black History Month: The Davidson sisters and inventors

To celebrate Black History Month, Isiah Carey has been sharing inventors who are responsible for making our everyday lives easier. Today he highlights the Davidson sisters. Together, Mary and Mildred Davidson created the toilet paper roll and the sanitary belt which helped women during their time of the month. Mary went on to create several more things including the walker -- which helped with her "multiple sclerosis." The sisters never became rich off their products and several were never even made because companies refused to work with Black women.
