If you close your eyes and picture a scientist, chances are you're seeing a man. We can't blame you, though. The assumption that science and innovation is a "men-only club" is still going strong. And women's contributions to science? Often treated like mere extras in a testosterone-filled blockbuster. This unfortunate perception has persisted, even after Charles M. Vest, MIT's former president, publicly acknowledged the rampant gender discrimination within his own institution. At MIT, women had fewer resources, earned lower salaries, and their influence... Let's just say they didn't have a front-row seat at the scientific symposium.

But there's a whole universe of things invented by women that changed the world in profound ways. Women have not just been a part of the STEM narrative but are often the authors of some of its most transformative chapters. Still scratching your head and wondering, "What have women invented?" Here's a sneak peek.

Got lost in the middle of nowhere during a road trip? We have Dr. Gladys West to thank for her work on the development of GPS. How about the wonder-material Kevlar, five times stronger than steel, used in everything from bike tires to bulletproof vests? That's Stephanie Kwolek's brainchild. Not forgetting the ever-practical dishwasher, brought to you by Josephine Cochrane. Next time you feel grateful for everyday conveniences that make your life so much easier, don't just assume there's a "he" behind these famous inventions. There's a good chance it may be a woman who used her brains, creativity, and tenacity to find a concrete solution to a shared problem.

Here's to celebrating the work of these unsung (s)heroes: the innovative women who've propelled humanity forward, one patent at a time! Our list features some of the most famous women inventors of our past who contributed greatly to science and technology. Plus, we'll highlight today's most noteworthy women in STEM who, standing on the shoulders of their brilliant predecessors, are actively shaping the world of tomorrow.

Margaret Eloise Knight – Paper Bag

Margaret Knight Photograph in a Boston Sunday Post Newspaper

Margaret Eloise Knight is known for inventing a machine that could shape and glue paper into a flat-bottomed bag. The popularity of her invention caught the eye of a man who stole her idea to patent it himself. When Knight took him to court, he stated that a woman "could not possibly understand such mechanical complexities." Knight won the case by proving that she had designed the machine, earning herself the right to patent it. She invented over 100 machines during her career and patented 20 of them.

Hedy Lamarr – Frequency-Hopping Technology

Hedy Lamarr was a glamorous black-and-white film star, but did you know she was also a gifted inventor? She worked with a composer to develop the principle of "frequency hopping," an innovation aimed at preventing torpedo control signals from being jammed by enemies. Even more impressively, this technology became the foundation for many modern-day inventions, including GPS and our precious Wi-Fi.

Gladys West – Global Positioning System (GPS)

Gladys West pictured with her husband, Ira West

In 1978, Gladys West became the project manager of Seasat, the first satellite to monitor the changing conditions and features of the oceans. Her work eventually evolved into GEOSAT, a satellite that could create models of the surface of the Earth. With her team, she developed a program to compute satellite orbits with extreme accuracy, assisting in the formulation of a mathematical representation of Earth's shape, the geoid. The geoid is a critical component of GPS technology, used to determine the precise location of a GPS receiver on the Earth's surface.

Capt. Godfrey Weekes, commanding officer at the Naval Surface Warfare Center Dahlgren Division, described the role played by West in the development of Global Positioning System: "She rose through the ranks, worked on the satellite geodesy, and contributed to the accuracy of GPS and the measurement of satellite data. As Gladys West started her career ... in 1956, she likely had no idea that her work would impact the world for decades to come." West agreed, saying "When you’re working every day, you’re not thinking, 'What impact is this going to have on the world?' You're thinking, 'I've got to get this right.'"

Sarah Breedlove – Specific Hair Care Products

Black and brown Sarah Breedlove portrait

Better known as Madam C.J. Walker, Sarah Breedlove became the first self-made female millionaire in the United States. She was only 20 when she realized that black women struggled with hair loss and scalp diseases because of inadequate plumbing and harmful product ingredients. Over several years, she developed her own hair care product line, specifically targeting African American people, and branded them as Madam C.J. Walker, chosen to evoke Parisian luxury. She also set up a school to train hairdressers. This initiative created employment opportunities for thousands of African American women. As her wealth and influence grew, she made considerable donations to African American schools, orphanages, and retirement homes.

After testing numerous materials, she created a coffee filter, obtained a patent, and established a business for its production. Within a year, she was selling hundreds of filters, and by 1928, her company was employing dozens of people. Known for her generosity and supportive work schedules, she also instituted "Melitta Aid," a welfare fund for her employees. And if the name sounds familiar, don't be surprised: the Melitta Group is still making coffee, coffee makers, and filters today.

I am very confused by this caption. Her work for the Dover Sun House had nothing to do with semiconductor thermoelectricity. Her heating/cooling system for the house operated on recrystalization of sodium sulfate. Her work at Westinghouse (1937-1939) largely involved thermoelectric devices which converted heat into electrical energy, likewise her later work at Curtis-Wright also involved thermoelectric generators (for early orbital applications!) By the time of the first "Thermoelectric Boom" in technology development (1954) between RCA and Westinghouse she had already left to work for New York University on solar stills, heating systems and ovens.

Jocelyn Bell Burnell talks about sience on TEDx show

In 1967, while analyzing quasar data from a radio telescope in Cambridge, astrophysicist Jocelyn Bell Burnell noticed fast, regular signals emanating from rapidly rotating stars. As she termed them, these pulsars earned her team the 1974 Nobel Prize in Physics — though the award was controversially bestowed only upon her male colleagues. Despite this, she brushed it off, saying that it was standard for the directors of studies, and not all the team members, to receive the accolade.
