Marjorie Stewart Joyner: Permanent Wave Machine

Marjorie Stewart Joyner

Marjorie was a woman who tried to solve African-american women's hair problems.

She was born on 1896 in Monterrey as the daughter of a teacher and a housewife, descendants of slaves.
Her parents got divorced and a few years later and she moved to Chicago.
Before she opened her beauty salon, she married Robert E. Joyner, a student of medicine.

There, she began working as a cleaner and as a waitress while she was in high school, which she could not finish.
Later , in an another school she graduated and was the first black person to graduate from that prodigious academy of cosmetics and beauty.

She opened a small beauty salon where she became famous for her ability with the "Marcel wave".
As straight hairstyle was difficult to do on black women, she decided to take lessons from a famous hairstylist for these women to release their complexes.

In 1919 she started to work in famous beauty salon ”The Walker Company ,and after the death of the head of the salon, Joyner became the head of the company .
In 1926, she wanted to solve the problem of most African-American's to straighten their hair so she created a machine to make it permanent.
She registered her machine in 1928 but could not be considered the inventor because a German man had already had the idea.A few years after making black women happy,
she  died in 1994 at the age of 98 in Chicago.

In our personal opinion, we think she was nice because she thought about helping black woman to overcome their complexes and feel better.

Picture extracted from: 

Kies invented and patented a new method by which the weaving of straw with silk and thread became more effective. This method reduced costs when manufacturing hats. She worked in Massachusetts.

Due to the Napoleonic wars, it was very difficult to import goods to the United States. They sold hats made of silk to the people that worked in the countryside.

But she not only invented that method, she was the first American woman to obtain a patent.
At that time, the women weren’t authorized to have possessions in their name. Unfortunately, the patent was destroyed because there was a fire in 1836 at the Patent Office.

She didn’t became rich because of the patent, but other people benefited from it.
