After she obtained the patent in 1980, she decided to set up a company, the famous German Melaleuca Company. Today, her grandson is controlling the company, and after years of development, Melaleuca Company It has become the Melaleuca Group, with more than 50 branches.

②Bette Nesmith Graham (March 1924-May 1980)

Bette Nesmith Graham was just an ordinary secretary, of course, in the early 1950s. Secretaries and typists at that time were very hard-working. Secretaries often had to retype an entire page because of a small mistake because it was too difficult to modify on the new strip copy paper. And Bette Nesmith Graham was so smart because she invented correction fluid! She got the idea when she noticed workers painting decorative paintings on bank windows to celebrate the holidays and simply covered up the mistakes with a layer of paint when they made mistakes.

Later, she sold the invention to Gillette for $47.5 million. By the way, she was also the daughter of former member of The Monkees, Michael Nesmith. Mother.

As an African-American woman, she was known as the No. 1 Beauty School in the United States (A.B. Molar Beauty School) at the time. While black women were graduating to smoothing or straightening their hair, Marjorie Joyner decided to find a new way to style her hair.

She thought of the paper used to cook braised beef, and she thought the same method could be used to create tools for bending or straightening our hair, and then she did.

The "perm" method she invented was welcomed by all women, and even attracted the attention of some entrepreneurs. It turns out that beautiful hair and beef have such a connection.

④Mary Anderson (1866-1953)

At that time, Mary Anderson was already a very successful real estate developer and rancher, but this did not prevent her from becoming an inventor. reasons.

In 1902, while traveling to New York, she noticed the trolley driver stopping every few minutes to sweep snow off his windshield. All drivers had to do this at that time. Then, inspired, she went home and created an automatic wiper that could be operated in the car (of course it was relatively rudimentary at that time)!

When she first tried to sell the patent in 1905, a prominent Canadian company even rejected her application as having no commercial value, and then in 1922, Cadillac placed it on its own car However, Mary Anderson's patent expired and she never received a penny from her invention.

Her invention allows those toilet paper rolls to appear in the corner of the bathroom very leisurely. You can use the rolls when you go to the toilet. Thanks to this woman...

Of course, Mary Beatrice Davidson Kenner has many other inventions, but none of them are as convenient as the invention of the bathroom tissue holder. Yes, almost every household is benefiting from it.
