8 Great Discovery by Women



At the end of the 20th century, only 10 percent of invention patents granted to women. Not that less intelligent than men, but it took dozens and perhaps hundreds of years until women can be equal in the eyes of men.

For example Sybilla Masters who lived in the 18th century when America was known for ages "wild-wild west". He innovate in the process of making corn flour. Findings to obtain patents registered at home to England in the year 1715. Ironic, because the future does not recognize intellectual property rights for women, then her husband, Thomas, who are entitled to the patent.

Then in 1809 Mary Dixon Kies became the first American woman who deserves a patent in his own name. He has developed a loom straw hat maker. Since then, women began to be accepted in the hegemony of men.

Calling list of findings initiated by women is now a great deal. We will see 10 lists are very useful in life.


1. Aramid or Kevlar

Aramaid or Kevlar is the material bullet-proof armor. The material was discovered in 1964 by Stephanie Kwolek, an American chemist, who worked as a researcher at DuPont company.

Aramid is an abbreviation of the word aromatic polyamide. Aramid has a structure strong, tough (tough), has a good damping properties (vibration damping), resistant to acids (acid) and bases (leach) and in addition it can withstand heat up to 370 ° C, so it is not flammable.

Because it is so, aramid is also used in aircraft, tanks, and aerospace (rocket). Products marketed known as Kevlar. Kevlar has a light weight, but 5 times stronger than steel.

2. Polonium and Radium

Marie Curie was a chemist and Polish-born French physicist who until now was the only person who had received the Nobel Prize in two different fields, the physics and chemistry.

Its discovery in the field of radioactive Marie Curie made into the list of influential inventors to the world. Marie Curie was the first woman Nobel Prize winner and also the first woman to become a professor at the university, Universities of Paris.

Marie Curie's work and research to make the chemists and physicists understand how to collect sources containing radioactive material to cure diseases as well as for research purposes in the more radioactive substances.

3. Chocolate chip cookies

Chocolate chip cookies eaten the most delicious afternoon drinking tea. The inventor was Ruth Wakefield, professor of nutrition and food experts.

She and her husband moved to Boston and opened a business lodging. One day in 1930 he was preparing a meal for guests. Wakefield require melting chocolate recipe that is perfect, unfortunately he ran out of material. Finally he took the Nestle chocolate bars, crushed into small pieces and thrown into the oven. He hopes that the chocolate will melt. It turns out that chocolate is actually produced small clot. That's the history of the birth of chocolate chips.

4. Mistake Out

Around the year 1951, Ms Graham became executive secretary of the frequent typing important documents. So no need to repeat typing documents every time there is a typo, it uses a potion he paints himself white. Apparently white paint plus a small brush, which he called Mistake Out was favored his friends as well. Eventually he established a factory Mistake Out.

5. COBOL

Rear Admiral Grace Murray Hooper joined the military in 1943 and was stationed at Harvard University, where he worked at IBM Harvard Mark I computer, the first large-scale computer in the United States.

In 1950, Admiral Hopper invented the compiler, which translates the command of human language (English) to the computer code. This device means that the programmer can make the code more easily and with fewer errors.

Compiler second setting was the Flow-Matic, is used to program UNIVAC I and II - the first generation of computers available for commercial purposes. Admiral Hopper also oversaw the development of the Common Business-Oriented Language (COBOL), one of the first computer programming language.

6. Colored Flare System

Colored Flare System (CFS) is a means of communication or as well as used emergency alert ships at night. Who knew that behind this great discovery of the hard work of a tough woman, Martha Coston.

In 1847 at the age of 21 he had a widow with four dependent children when her husband died. He did not know what to do, until one day, flipping through her husband's records and found the design tool of communication for ships at night.

Coston and spent up to 10 years to revise and refine the design of her husband. He consulted with scientists and the military but have not found the right answer. Until finally one night when bringing children to see the fireworks, he got an idea that could be applied to the instrument makes.

Ironic, though he has been helping the military during the Civil War by spending 1.2 million CFS, instead he owes up to $ 120,000 and the U.S. Navy at the time did not want to pay just for stupid reasons: that a woman Coston.


7. Dishwasher


Josephine Cochrane in 1883 following the death of her husband inherited a large debt. In desperation his brain working hard to make a dishwasher (dishwasher). Finally in 1886 the machine was completed and got the patent.

Initially he had trouble selling the machine for homemade dishwasher needs hot water in order to function, while at that time not many households that have a hot water heater. Finally Cochrane focuses on hotels and great restaurants. Cochrane reason that the engine behavior, the dishwasher the hotel and restaurant businesses do not need to hire more employees just to work washing dishes.

8. Wiper

At the beginning of the 20th century, Mary Anderson's visit to New York. Conditions in the city of the 'Big Apple' when it just started crowded by car traffic although not so much.

During the tour, he rode the tram and always stop every few minutes because the driver had to wipe the snow on the windshield. Incidentally it was winter. Mary Anderson noticed this, it turns out all the drivers do the same thing.

When he returned to Alabama, designed a device that can be attached to the windshield. When the driver to clean the glass, he did not need to go down and pull the handle on the handle enough to clear the snow.

Mary Anderson received a patent in 1903, and 10 years later the cars in the United States are already using wiper creations.
