10 inventions by women that changed the world (PHOTOS)

Women are used to dealing with the difficulties they encounter in the labor market and in everyday life.

That is why it is surprising to know which important inventions we use were developed by brave women who definitely broke the standards of the time in which they lived and left us a whole legacy.

Tools like syringes, windshield wipers, and Kevlar, the resistant fiber used in bulletproof vests, among many others, were created by women ahead of their time.

Below are the inventions along with the women who made them.

Glass cleaner

This indispensable tool to provide better visibility for drivers on rainy days was created by Mary Anderson in 1903, who came up with the idea after being forced to drive in the middle of a snowfall, realizing the difficulty and importance of keeping of clear glass.

Coffee filter

Melitta Bentz, a housewife found that cleaning the cloth coffee filters used at the time was extremely tedious.

So she decided to try to figure out a new way of filtering it. After doing a few tests, she decided to take a tin cup and drill some holes in it. She took a sheet of paper from her son's notebook, filtered the drink, and the result was amazing.

Melitta realized it in 1908 and soon after, she started her own business. Years later, during the First World War, the company faced many difficulties, but managed to grow despite everything.

Melitta was also concerned about the welfare of her employees, so she decided to extend their holiday season, reduce their working hours, give them Christmas bonuses and create a social fund for them. Today, the company remains strong and is managed by family members.

Injection syringe

An American nurse, Letitia Mumford Geer, was responsible for creating the first piston syringe, which was produced in 1899.

This enabled doctors to perform it with one hand. Undoubtedly, this was an important innovation in the field of health and extended to many other sectors, in addition to serving as a starting point for the syringe we know today.

Children's diapers

Marion Donovan created the first disposable liquid resistant diaper.

The idea appeared shortly after World War II, when she was fully devoted to her family life and domestic activities. With a sewing machine and a shower curtain, she managed to create her first prototype.

Donovan also invented plastic gloves to replace diaper pins. These and many other inventions earned her a place in the inventors' hall of fame.

sink

Josephine Cochrane built the first dishwasher in 1886.

A few years later, it managed to attract the interest of restaurant entrepreneurs during a fair in Chicago, but the car gained real importance in the 50s, a period when it became more accessible to consumers.

monopoly

Elizabeth J. Phillips was the creator of Monopoly in 1904.

Initially, the idea of ??this was to convey the notion of economics and demonstrate how harmful the capitalist system was. Monopoly spread like it was created by Charles Darrow.

Fortunately, after meeting the true creator, the company looked for a way to compensate Lizzie Magie, as she was known to everyone.

Lifeboat

After the success of her invention to speed up the production of barrels, Maria Beasley decided to create a lifeboat that was more compact, safer, resistant to fire and water, and easy to use.

In 1880 she developed the new model. She did not imagine that years later her lifeboats would help many people on the most famous ship in the world: the Titanic.

Invisible glass

Katharine Burr Blodgett was the first woman to earn a doctorate in physics at Cambridge University in 1926.

Years later, she invented low-reflective glass, which helped improve the camera, microscope, and projector technology of her time. Its technology was even used to film the famous movie "Gone with the Wind".

Kevlar, the tough fiber used in bulletproof vests

Stephanie Kwolek, who had a PhD in chemistry, was the creator of the extremely strong fiber known as Kevlar.

This thread can be up to 5 times stronger than steel and is used to make bulletproof vests and many other products.

Wireless, wireless network

Actress and inventor Hedy Lamarr developed, in partnership with her friend George Antheil, a technology known as the precursor to Wi-Fi.

Its idea allowed remote control of torpedoes, as well as preventing their interception by enemies, by changing the frequency of radio signals in a spectral band.

However, at that time, the "United States Navy" did not want to implement the invention, which only began to be used many years later.

Fortunately, in the late 1990s, the duo received a major award for their discovery, and in 2014, Lamarr entered the inventors' hall of fame.

These and many other women revolutionized the world and became examples of strength, courage and determination!
