Mary Beatrice Davidson Kenner (1912 – 2006) – Sanitary belt
Mary Beatrice Davidson Kenner invented the sanitary belt, patented it in 1957, and revolutionized menstrual hygiene. Before her invention, most women were still using cloth pads for menstruation. The sanitary belt had a moisture-proof pocket and was adjustable to fit any user comfortably. Kenner also invented a toilet tissue holder, a back washer mounted on the shower wall, and a serving tray attached to a walking frame. Despite her many useful ideas now still widely used, Kenner was perhaps one of the most forgotten African American inventors.
