Mary Kenner

 Born in 1912, Mary Kenner’s creativity and ingenuity was evidenced by the five different patents she received during a 21-year time frame. In 1956, Kenner received a patent for inventing the Sanitary Belt. Three years later, she received another patent for inventing a sanitary belt with a moisture-resistant pocket. In 1976, Kenner invented an attachment for an invalid walker. In 1982, she invented the toilet-tissue holder, and in 1987, she received a patent for a backwash that was mounted on a bathtub and shower wall. While these inventions did not make her rich, Kenner stated that she enjoyed the idea of making life more convenient for other people.
