Do you think the wireless connection and beer were invented by men, asks Rambler? No matter how wrong! All this is women's discoveries, although representatives of a strong half of humanity love to talk about the small role of women in scientific and technical progress. We can do a lot - and these seven female inventions are proof of that!
Paper bags
In the 1871 year, after a lawsuit with a colleague trying to arrogate to herself her achievement, Margaret Knight received a patent for a device that makes paper bags. At that moment, almost half of the residents of the United States could work in addition to housework, and, oddly enough, paper bags helped improve this indicator. The fact is that the schools did not feed the children, and it was not easy to give them food from home, so the mothers stayed at home to feed the schoolchildren. Paper bags saved the day.
Wireless communication
Wi-Fi came up with a Hollywood beauty, the star of the screen Hedy Lamarr, about which we already wrote. She was not only a talented actress, but also a wonderful inventor. For a long time the woman was not taken seriously, but she managed to change that. It was Lamarr who figured out how to safely transfer data between military objects, inventing a kind of secret communication system. Later, this technology formed the basis Wi-Fi and Bluetoothand GPS.
Beer
The adored "male" drink is actually purely feminine - it was invented, as historians say, by the women of Mesopotamia, making the drink by fermentation. Then only women were engaged in kitchen, and this invention could not belong to anyone else. In Finland and England, women ran taverns, brewed beer and provided for the family.
Non-glare glass
Catherine Blodgett - the first woman who was able to get her doctorate at Cambridge, and the first woman hired by the concern General Electric. During World War II, she figured out how to produce gas masks, coatings for aircraft wings, and even create smoke screens. The same author owns the invention of glass without glare - first, the military introduced it into telescopes, so as not to be seen by the enemy, but now such glass is used everywhere.
Coffee filters
The German housewife Melitta Bentz used the method of filtering coffee grounds through a layer of thick paper - only pure liquid without impurities was in the cup. Prior to this, coffee was placed in a bag and dipped in a container with water. The taste of coffee has improved, and this technology is still used. In 1908, Bents received a patent for her invention.
Garbage cans with pedals
Every housewife many times a day uses a trash can, and each time it is not only inconvenient but also unhygienic to open it and close it with our hands. Lilian Gilbret at the beginning of 1900-ies offered to equip trash can with a pedal, and she also invented shelves for refrigerators and several ways to open cans.
Car wipers
A woman invented them too! Mary Anderson invented windshield wipers in 1903 to make it a little easier for men who were constantly shoveling snow from the windshield of a car with their hands. She received a patent, but the men did not appreciate the novelty. And only 20 years later, Henry Leland, the owner of Cadillac, took Anderson's idea and used it. Now it is impossible to imagine a single car without wipers.
