Let's be real: every day is a celebration of women's existence. But on March 8th, in particular, the purpose of International Women's Day (IWD) is for us to bring attention to the "social, political, economic, and cultural issues that women face, and to advocate for the advance of women within all those areas." According to IWD advocates, this year's theme, #BalanceforBetter, is meant to promote gender balance for economies and communities to thrive. As IWD reports, balance is not a women's issue — it's a business issue. And we, as a global community, must fight for "the gender-balanced boardroom, a gender-balanced government, gender-balanced media coverage, a gender-balance of employees, and more gender-balance in wealth."

This day is much more than a celebration — it’s a call to action for everyone to continue the push for gender equality worldwide. In honor of this momentous day, here are seven extraordinary Black women who've made significant contributions to the advancement of our Black, female community.

1. Mary Kenner — Inventor

Mary Kenner was an American inventor who revamped the world of feminine care with the invention of the sanitary belt (aka the maxi pad). In 1956, Kenner's sanitary belt, equipped with a moisture-proof napkin pocket, offered women a better alternative for handling their periods. Though multiple feminine hygiene products refused to sell Kenner's invention simply because she was a Black woman, Kenner went on to patent other household items including the bathroom tissue holder, a back washer that mounted on the wall of the shower, and the luggage-carrier attachment on walkers for disabled people.

2. Byllye Yvonne Avery — Activist

As the founder of Black Women's Health Imperative (formerly the Black Women's Health Project) — the first national organization to specialize in Black women's reproductive health issues — Avery has rightfully be awarded for contributions to the health care industry.

Marjorie Joyner was a beauty salon owner, who changed the game of hair styling when she invented the “permanent wave machine.” Her perm machine simplified the process of straightening and curling hair for all women, and made Joyner the first Black woman in history to receive a patent for her work. Unfortunately, despite the popularity of her invention among Black and white women, Joyner did not receive any profit from the invention as the rights were owned by Madam C.J. Walker’s company.
