Leona Chalmers, Mother of Menstrual Cups

In 1937, Leona Chalmers seems to have produced the first commercial menstrual cup.


It was remarkably similar to cups made today.


The Tass-ette Cup could not out-sell Kotex, which is rather like cups today -- women prefer to use paper products rather than cups when dealing with the curse.
