Kennerβs first and most mentioned patent was in 1957 for the sanitary belt, used to hold napkins before adhesive-backed pads and tampons were invented. She created the belt 30 years prior in the 1920s but could not afford a patent. Kennerβs following four patents included a sanitary belt with a moisture-resistant pocket, a toilet tissue holder, a hard-surface tray and pocket for holding items that mount to wheelchairs/walkers, and a wall-mountable back washer and massager.
Mary Beatrice Kenner died without having received fame or wealth on January 13, 2006.
