History’s spotlight loves the usual suspects. Meanwhile, the women doing the legwork, breaking ground, and rewriting the rules are filed under “miscellaneous.” This list pulls them out of the footnotes and hands them the mic.
Some wore lab coats, some laced boots, but all earned more recognition than they received. If you haven’t heard of them yet, you’re about to wonder why.
Mary Eliza Mahoney
Mary Eliza Mahoney became the first Black woman in the U.S. to earn a professional nursing license in 1879. She trained in Boston, graduating when few women (let alone Black women) could even apply. She also co-founded the National Association of Colored Graduate Nurses and pushed the profession forward when no one else offered her a seat at the table.
Dr. Mary Edwards Walker
Before women could vote, Dr. Mary Edwards Walker had already served in the Union Army, been a prisoner of war, and earned a Medal of Honor. She didn’t want to be first, but to be useful. She chose medicine, treated the wounded, and stood up in courtrooms and lecture halls wearing whatever she liked. Her work spoke for itself, louder than any dress ever could.
Mary Jackson
Mary Jackson started as a math teacher and ended up as NASA’s first Black female engineer. The middle part? She worked through segregated facilities, buried her name behind white male titles, and took night classes in a segregated school to qualify. She didn’t coast. Instead, she rewrote what was possible for women in STEM, then turned around and helped others climb, too.
Emma Tenayuca
In Depression-era Texas, pecan shellers made pennies a day, and Emma Tenayuca made that everybody’s problem. She organized workers, held marches, and gave fiery speeches no one could ignore. The city blacklisted her. The movement didn’t. She kept speaking, kept pushing, and gave working-class Latina women the power to strike back. At 21, she led a walkout. At 22, she’d made history.
Josephine Peary
Josephine Peary packed a fur-lined parka and joined Arctic expeditions while most women were packing for tea. She traveled to Greenland in the 1890s, braved ice storms, gave birth in near-total darkness, and wrote bestselling books about the Arctic before her husband took the credit. She didn’t need to plant flags to prove anything; she proved enough by showing up and staying longer than they did.
Dorothy Vaughan
Dorothy Vaughan (left) supervised a team of Black women computers during segregation, helped launch satellites, and rewrote the future of tech without much thanks from the present. She worked at NACA, later NASA, leading a segregated team of Black women computers. She transitioned her team into the machine age, coding in FORTRAN before most knew what it was.
Elizabeth Le Blond
Victorian women weren’t exactly encouraged to climb mountains. Elizabeth Le Blond did anyway. Corset and all. She tackled the Alps, shot early mountaineering films, and took photographs on snow-covered peaks while the men debated who got credit. Spoiler: not her. She didn’t stop there; she founded the Ladies’ Alpine Club in 1907 so other women could do what she wasn’t supposed to do either.
Georgia E. L. Patton Washington
Born enslaved in 1864, Georgia Patton Washington became a physician three decades later. She earned her degree at Meharry Medical College and brought care where others didn’t: rural Tennessee, the West Indies, poor neighborhoods, and crowded cities. She knew medicine wasn’t about titles, but showing up. Her tools were basic, her time short, her service lasting. She died young, but she changed how people lived.
Hedy Lamarr
Movie star by day, inventor by night. Hedy Lamarr lit up 1940s Hollywood, but her brain outshone the spotlights. She co-created a radio tech system to block Nazi torpedoes, a concept that helped build modern Wi‑Fi. She wasn’t formally trained; she saw gaps and connected the dots. Studios called her beautiful. Engineers later called her brilliant. Turns out she had more range than anyone guessed.
Patsy Mink
Patsy Mink didn’t come from privilege, but she built policy like someone who knew the system. As a Congresswoman, she wrote protections for women, students, immigrants, and children. Title IX is the headline, but her portfolio ran deep. She knew what it meant to be locked out, and she wrote people back in. Her laws outlived her, and so did the opportunities she made possible.
Mary Kenneth Keller
Sister Mary Kenneth Keller became one of the first people in the U.S. to earn a PhD in computer science in 1965. She didn’t just learn FORTRAN. She taught it, built programs, led departments, and believed computers should be accessible to everyone. She helped design early educational tech, then built opportunities for women who weren’t expected to belong in tech.
Claudette Colvin
Claudette Colvin didn’t have a polished reputation or civil rights mentors cheering her on. She was a teenager on a crowded bus who said no. She was handcuffed, kicked out of school events, and nearly erased from history. Her story didn’t make national headlines. She wasn’t the face of the boycott, but her name is in the lawsuit that changed everything.
Henrietta Lacks
Henrietta Lacks didn’t donate her cells. They were taken during treatment, and no one told her. What followed changed modern medicine. Her cells (HeLa) became the first to thrive in labs. They were used to test polio vaccines, cancer treatments, IVF, and more. Her story isn’t just medical history. It’s about rights, race, and finally being acknowledged.
Katherine Johnson
Katherine Johnson liked solving problems. The bigger the better: calculating rocket launches, reentry paths, and more. She started at NASA in a segregated unit and ended up writing parts of the flight plan to the moon. John Glenn asked for her by name. The computer’s numbers weren’t enough; he only trusted hers. That’s how essential she was. Her work was precise, and her impact was planetary.
Alice Hamilton
Alice Hamilton became the U.S.’s leading expert on industrial toxins by walking into smelters and sweatshops with a notebook. She chased down toxic chemicals, exposed unsafe working conditions, and called out the industries causing them. She didn’t win popularity contests; she won safer laws. Harvard hired her but didn’t give her full rights. She kept showing up. That’s how change happens. Relentlessly.
