Born: May 17, 1912
Biography:
Mary Beatrice Davidson Kenner, born on May 17, 1912, was an American inventor best known for her remarkable contributions to women’s hygiene. Despite facing racial discrimination, Kenner’s ingenuity led her to develop the adjustable sanitary belt, revolutionizing the way women managed their menstruation. However, it was not until thirty years later that her patent for the sanitary belt was finally granted.
Kenner hailed from a family of inventors and inventiveness. Her father, Sidney Nathaniel Davidson, held a patent for a clothing press designed to fit in suitcases, although he unfortunately never profited from this invention. He also invented a window washer for trains and a stretcher with wheels for ambulances. Kenner’s grandfather invented a light signal for trains, but racial injustice caused it to be stolen from him by a white man. Even her sister, Mildred Davidson Austin Smith, created, patented, and successfully sold board games.
Growing up in Monroe, North Carolina, Kenner’s passion for discovery was nurtured by her father. She attended Dunbar High School, graduating in 1931. While she desired to continue her education at Howard University, financial constraints prevented her from doing so. It was an era where women, particularly African American women, faced substantial barriers to accessing scientific establishments and academic institutions.
As opportunities for her ideas to be patented emerged, Kenner moved to Washington, D.C., where she remained close to the United States Patent and Trademark Office. In 1954, she submitted a patent application for her most significant invention, the adjustable sanitary belt. This ingenious creation included a moisture-proof napkin pocket, aiming to eliminate the chafing and irritation often caused by similar devices. Two years later, in 1956, the application was approved.
Sadly, the company initially interested in manufacturing Kenner’s invention, the Sonn-Nap-Pack Company, rejected her after discovering she was African American. This prejudice resulted in Kenner never profiting from her sanitary belt, as her patent expired, entering the public domain.
Undeterred by this setback, Kenner continued to dedicate herself to innovation. She later introduced a modified version of the sanitary belt, incorporating a moisture-resistant pocket.
Kenner’s struggles and accomplishments demonstrate her resilience and unwavering commitment. Her drive to address women’s needs and improve their quality of life was a testament to her compassion and vision. Despite the racial discrimination she faced, Kenner’s inventions left a lasting impact on society.
