Leona Chalmers was born around 1886, though the exact date and location remain unknown due to limited biographical information. Her early life is largely undocumented.

Little is known about Chalmers' childhood. Given the era, she likely received a basic education, possibly focusing on subjects considered appropriate for women at the time, such as reading, writing, and domestic skills. Access to higher education for women was limited, but not entirely absent, in the late 19th and early 20th centuries.

It can be assumed that during this period, Leona Chalmers developed the ideas that eventually led to her invention. Exposure to the social stigmas and inconveniences surrounding menstruation likely played a significant role in her desire to create a more practical and comfortable solution. The prevailing limited options of reusable cloths would have been commonplace.
