She invented the dishwasher, with the help of the mechanic George Butters. Her childhood was very comfortable; she lived in a wealthy family. Her father was a civil engineer, and her grandfather was an inventor who influenced her creativity and curiosity.

The dishwasher is important because it saves time and water, improves hygiene, and promotes technology in the home. She created it by designing a machine with grates to hold the dishes and water jets to wash them.

In those times, it was not common for women to invent things, so she had some difficulties in creating her project, such as technical problems and limited funding.

She died in Chicago, Illinois, on August 3rd, 1913, at 74 years old.

A fun fact about Tu Youyou is that she won the Nobel Prize in Medicine in 2015 (the first for a Chinese scientist) without having a doctorate degree, a foreign medical degree, or studies outside of China, basing her discovery of artemisinin on ancient texts of traditional Chinese medicine.

She got married at seventeen. Later, she started working as a typist in an office.

In those days, there was no way to erase mistakes, so she had to start over every time.

One day she had an idea: covering the mistakes with white nail polish. She called it "Mistake Out" and started using it at her work.

Later, Nesmith improved her invention, renaming it "Liquid Paper", and selling it from her home. Her make became very successful, and because of this she was fired from her job. She finally sold her company for about 50 million dollars.

She then died of a stroke in 1980.

Nowadays, it is a product sold everywhere, and something we use daily, so we thank Bette for her ingenious invention.

She was a trailblazing ophthalmologist, and she invented the Laserphaco Probe in 1986. This machine revolutionised cataract surgery by using lasers to painlessly and precisely remove cataracts. She graduated from Hunter College and after that she studied at Howard University College of Medicine.

It’s important to mention that she was an African-American woman and faced discrimination and sexism. Of course, this made things more difficult for her, but she never backed down. Instead, she kept searching, studying, and inventing.

She was born on November 9th, 1914, in Austria. She was interested in arts and technology from a young age. She started her artistic career as an actress in Europe during the 1930s. Later, she moved to the United States, where she became famous. She was considered one of the most beautiful women in the world. Considering the society of that time, it was unusual for a woman like her to make such an important invention, which is why her contribution was recognized much later.

During World War II, she attended several meetings organized by people from the same artistic environment as George Antheil, a composer who shared her interest in arts and technology. Focusing on the war effort, they cooperated to create a secret communication system called frequency hopping.

She died on January 19th, 2000, in Casselberry, Florida. She was later recognized as a great inventor, and her invention helped develop modern systems such as Wi-Fi, Bluetooth, and GPS.

Her first patent (1912) was for inventing the parasol, which became very popular when she created the Henry Umbrella and Parasol Company in New York. But it wasn’t the only thing she did—she also created the ice cream machine, the radio doll (a toy that could speak), colourful designs for bags and parasols, and over 110 other inventions. She didn’t get a patent for all of them, but she was still very acclaimed and well-known. Her impact was big, not only in the United States, but also in England and Canada. She later died on February 1st, 1973, at 85 years old.
