Black Inventors Who Made the World Safer #shorts #blackhistorymonth
Happy Black History Month!
Here's some more info about each of these inventors.
Marie Van Britton Brown (1922-1999) - Inventor of the First Home Security System
Brown and her husband, Albert, patented the first home security system in 1969. It was complete with two-way microphones to speak to anyone on the other side, peepholes and cameras, and even a call button to reach emergency help.
As a night shift nurse, Brown was tired of feeling unsafe walking home late at night. So she and her husband created this system that isn't too different from what we use today. She went on to patent more devices throughout her lifetime.
Garrett Morgan (1877-1963) - The Traffic Signal and Gas Masks
Garrett Morgan created the first versions of the traffic signal and gas masks. His breathing device prototype was used in WWI and he later personally used it to save two lives in the 1916 Cleveland Tunnel Explosion.
Dr. Charles Drew (1904-1950)
Medicine wasn't in Dr. Drew's plans until he lost his sister to tuberculosis. He attended prestigious universities and worked with transfusions in their early days. His contributions to Britain in WWII lead to the first mobile blood-collecting unit, known as the "bloodmobile".
Dr. Marian Croak (1955-present)
Dr. Croak holds claim to over 200 patents, including VoiP (voice over internet protocol) systems that allow us to make voice calls over the internet. Her work started in 1982 with AT&T Bell Laboratories working in voice and data communications for over thirty years.
She left AT&T in 2014, and now leads Google's Research Center for Responsible AI and Human Centered Technology.
