It goes without saying that African Americans helped to build and shape this country and civilization. Many know that African Americans were responsible for many great inventions over the years, but there are some inventions that we take for granted on a daily basis that many don’t know we’re invented by African Americans. So in honor of Black History Month, SoulTrain.com spotlights just some of the many inventions created by unsung African Americans.
Nowadays, there are many advanced and sophisticated home security and surveillance systems. Back in the 1960s, however, such systems were not even thought of beyond the simple burglar alarm. In 1966, Marie Van Brittain Brown and her partner Albert Brown applied for an invention patent for a closed-circuit television security system they created.
The folks at Bon-Ton and Wise Potato Chips can thank an African American man for one of the most favorite snacks in the world. In 1865, Hiram Thomas was a chef who created the potato chip out of frustration. An irate customer kept repeatedly sending his serving of potatoes back to the chef for thinner slices. In defiance, Thomas cut the potatoes into very reed thin slices to irk the customer. However, the customer loved them!
Imaging X-Ray Spectometer
George Edward Acorn received a B.A. in physics, a master’s degree in physics, and a PhD in atomic and molecular physics. Still, with all of those credentials, Acorn is most noted for his innovation of the imaging of the X-ray spectrometer.
Imagine a world without this invention! On December 19, 1899, J.B. Rhodes invented the water closet. Today, it is commonly known as the toilet or commode. Before this invention, many people were using outhouses. It wasn’t until Rhode’s invention that people could use the bathroom in their own homes. And speaking of toilets, Robert Shurney, another black inventor, designed the toilet used aboard the Skylab.
