The Brilliant Woman Behind Sanitary Pads Invention Has 5 More Patents For Life-Changing Inventions!
Mary Beatrice Davidson Kenner was an extraordinary inventor who made significant contributions despite facing numerous challenges. Born on May 17, 1912, in Monroe, North Carolina, Kenner was most famous for developing the sanitary pad. Throughout her life, she received five patents for her inventions, which improved daily living and hygiene. The walker attachment, toilet paper holder, adjustable sanitary belt (a predecessor to the maxi pad) along with mounted back washer and massager are some of her patented inventions.
Despite encountering racial discrimination, she left a lasting legacy of innovation and made everyday life easier. Not only Mary but her whole family is known for innovation. Let’s dive into her story and other contributions.
Mary Kenner’s Invention of the Sanitary Belt
Mary Kenner invented the adjustable sanitary belt in the early 20th century. At that time, menstruation was a taboo subject, and women often used homemade sanitary products. Commercial options like Kotex pads were uncomfortable and only occasionally used.
Kenner’s sanitary belt addressed these issues. The belt secured sanitary napkins in place, prevented menstrual blood from staining clothes, and provided comfort and ease of use. She conceived the idea in the 1920s but could not afford to patent it until about thirty years later.
In 1954, Kenner completed the patent application for her sanitary belt, and it was granted in 1956. Despite the invention’s potential, the Sonn-Nap-Pack Company rejected it upon learning that she was African American. This racial discrimination prevented Kenner from profiting from her invention, as her patent eventually expired, making the sanitary belt public domain.
Overcoming Racial Discrimination and Patenting Her Innovations
Kenner faced significant racial discrimination throughout her career. Despite these obstacles, she managed to secure patents for her inventions between 1956 and 1987. This was a remarkable achievement, as she held the most patents of any African American woman at the time.
Kenner once recounted her experience with a company interested in her sanitary belt, only to lose interest upon discovering her race: “Sorry to say, when they found out I was black, their interest dropped.”
