You’ve probably guessed that inventions of mankind, such as the bra, diapers, dishwasher, or chocolate chip cookies, were probably invented by a woman. How about the car muffler or the circular saw? The 10 best inventions of women will break the stereotype that most technical inventions belong to male scientists.
1. The astrolabe is an ancient device for measuring the coordinates of celestial bodies. Back in 370 BC, it was invented by the woman philosopher, astronomer and mathematician Hypatia of Alexandria.
2. Kevlar, a material that is five times stronger than steel, was invented by Stephanie Louise Kwolek, a material used to make ropes on oil rigs, car bodies, military helmets, radial tires, cables for suspension bridges and much more. She is also known as the inventor of body armor and flame retardant clothing.
3. Observing her brothers, who spent a great deal of energy cutting logs with a special two-handled saw, Tabitha Babbitt invented the prototype circular saw in 1810.
4. The periscope for submarines, which determines the distance to observed objects, was invented by Sarah Mather in 1845.
5. The first car wipers were invented by Mary Anderson in 1903, again after observing the driver’s futile efforts to clean the glass by hand during a blizzard, stopping the car each time.
6. The sound filter for the car, the muffler, was invented in 1917 by El Dolores Jones.
7. The prototype Wi-Fi was invented by the scandalously famous actress Hedy Lamarr, who starred in the acclaimed film Ecstasy, which featured the first nude bathing scene in cinematic history. After marrying a gun maker, Heady became fascinated with physics and in 8. 1941 patented a communications device that dynamically changed the frequency of the broadcast. This jamming radio transmission technology became the basis for Wi-Fi in 1991.
9. Patricia Billings, who wanted to be a sculptor, worked with plaster and was very upset when her sculpture crumbled. She experimented with materials for eight years and eventually invented silicone, which was not only durable but also fireproof.
10. The ROOMBA round robot vacuum cleaner was invented in 2002 by Helen Greiner, president and co-founder of iRobot. The prototype was the funny barrel-shaped robot from the movie Star Wars, which was Helene’s favorite character as a child.
While working at NASA, Barbara Askins invented a method of improving photographs with radioactive materials, which has also become used in X-ray technology.
