There are thousands of famous inventors from Africa that changed the world we live in today. Lets take a look at a few of the female inventors and their brain storming ideas;
Bessie was a physical therapist working with injured soldiers during world war 2. Due to the fact that the injured wanted to do more on their own instead of being assisted to feed, she invented an assistive device that permitted people who had lost limbs to feed themselves. Bessie Griffin was born in Hickory Virginia now Chesapeake Virginia. The electronic device she came up with could dispense bites of food without the person needing to use their hands. The invention featured a rubber tube through which liquefied food could be dispensed directly into a person's mouth by biting down the tube.
Dr. Patricia Bath (1942)
Invented the Laserphaco probe, a device that corrects cataracts( cataract is a clouding of the lens in the eye that decreases vision) during eye surgery. Cataracts are eye conditions that lead to blindness and Bath's device provided a less invasive, safer method of removing them. Her love for humanity and passion for helping others inspired her into becoming a physician. Patricia Bath is an innovative research scientist and advocate for blindness prevention, treatment and cure.
Marie Van Brittan Brown (1922-1999)
Brown was the first person to develop a patent (licence) for closed-circuit television security(CCTV). Her system was designed with four peep holes and a motorized camera that could slide up and down to look at each one. Brown's invention became the framework for modern closed-circuit television system that is widely used for surveillance, crime prevention and traffic monitoring. The security system was invented in 1966. Brittan Brown was born in Queens New York and died at age 76. Anything the camera picked would appear on a scanner. She received an award from National Science Committee. It was originally intended for domestic uses until many businesses began to adopt her system due to its effectiveness. The device enables a home owner to use a television set to view the person at the door and the caller's voice.
Betty Harris (1940)
She worked extensively in the area of explosives which led her to obtain a patent for her invention of a spot test for identifying explosives in a field environment. In 1999, she received the New Mexico Governor's Trail blazer Award for her achievement. Betty is an American Chemist, born on 29th July 1940 in Monroe Louisiana. She is recognized as a distinguished African American Scientist by the National Academy of Sciences (NAS).
Theora Stephens (1915- 1996)
She was the first person to patent the curling iron in October 1980. She created pressing and curling iron in 1983. Theora was also the inventor of flat iron.
Miriam E. Benjamin (1861-1947)
Inventor of the signal chair for hotels and the second black woman to receive a patent in U.S. The chair would reduce the expenses of hotels by decreasing the number of waiters and attendants, to add to the convenience and comforts of guests and to eliminate the necessity of hand clapping or calling aloud to obtain services. The chair worked when the person sitting would press a small button on the back of the chair which would send a signal to a waiting attendant. A light would illuminate as well allowing the attendant to see which guest needed attention. This system is used on airplanes for passengers to seek assistance from flight attendants.
