Welcome back to Black History Fun Fact Friday. Today, I’d like all of the women readers to thank Beatrice Kenner!
Some of the most common forms of protection for women during their cycles were grass, rabbit skins, sponges, rags, menstrual aprons, homemade knitted pads, or other absorbents. Usually, women used some form of cloth back in the day. These cloths are why “she’s on the rag” is a popular expression used to refer to menstruating women.
While she did not invent the modern version of the Maxi Pad, Mary Beatrice Davidson Kenner developed the sanitary belt, one of the first versions of the modern-day pad.
Mary was born in Monroe, North Carolina, on May 17, 1912, and came from a family of inventors. Her sister invented a children’s board game that explored family ties called “Family Treedition.” Mary’s father, Sidney Davidson, patented a pants presser in 1914. According to historian and former U.S. Patent Examiner Patricia Sluby, a maternal grandfather of the daughters was of German and Irish descent who invented a tricolor train light. It’s safe to say that developing things was in Mary’s blood, pun intended.
The sanitary belt was a belt used to hold pads in place before designing self-adhesive maxi pads.
Mary invented the sanitary belt with a moisture-proof napkin pocket, but the company that showed interest in the pads rejected the invention because Mary was a black woman. For this, the sanitary belt didn’t become widespread until 1956, thirty years after its design. Learning this has taught me the power of patience and how everything comes to be in its time. It may have seemed like a lifetime to Mary, but eventually, her invention saw the light of day. Mary received five patents for her invention between 1956 and 1987.
While mostly known for her invention of the sanitary belt, Mary had other groundbreaking designs like the toilet paper holder, and the mounted back scrubber and washer for showers. Mary has been an entrepreneur from the start, operating her own floral business in Washington, D.C., when she was not inventing things.
Adhesive Maxi Pads (a sticky side that stuck to the lining of a woman’s panties) were invented in the 1970s, so the sanitary belt did not last very long. But without the belt, someone would not have thought to make things easier by eliminating the belt and just going with the napkin.
If you are a young woman like me and have never used the belt, you can Google Sanitary Napkins (or talk to your mom or grandmother), and learn that the strap was uncomfortable and inconvenient. While tampons existed, using them for younger women was considered sexually improper. (A pretty good article to study up on the evolution of pads can be found HERE.)
Life happens in stages, and good things come to be because someone took a risk on something others may not have found useful. Mary’s invention helped women who didn’t want to use tampons to get by and paved the way for all of the pads currently on the market.
