Judging by U.S. history books, the only Black inventor was George Washington Carver (although in Indiana we also learned about Madame C.J. Walker, whose factory still stands in downtown Indianapolis and is now a theater). But the fact is that his podium is a rather crowded one. Here are some of the many other Black innovators:

• Lewis Latimer: started as an inventor at Maxim’s U.S. Electric. In 1884, he was hired to work with Thomas Edison. He later became Edison’s chief litigator in patent conflicts. He also wrote the first book on electrical lighting. He later became the only Black member of the elite Edison Pioneers.
• Garrett Augustus Morgan: In 1912 he invited the gas mask which soon became an indispensable tool for firefighters. He also invinted the automatic three-way stop sign (predecessor to the traffic light)
• Shelby Davis: Created the adding machine (an early calculator) to make work at the Postal Service more efficient.
• James Jones: Created the patent for the convertible car in 1919
• Frederick McKinley Jones: Invented the x-ray machine, a refrigerator for military field kitchens, and the mechanical refrigeration techniques applied to railroad cars
• Michael Croslin: Created the Medtek 410 - the first computerized blood pressure measuring device
• Ralph Gardner: His research into plastics led to the development of hard plastics. He also helped build the first nuclear bomb, but i don’t know that’s something to brag about.
• Dr. Charles Drew: Standardized blood drawing and storage procedures. His work on the separation of plasma led to the modern day blood bank.
• Dr. Jane Cooke Wright: the first doctor to see remissions in skin cancer mycosis fungoides patients and in solid breast cancer tumor patients.
• Dr. Levi Watkins, Jr.: performed the first surgical implantation of the automatic implantable defibrillator in the human heart.
• Dr. Ben Carson: the first to successfully separate conjoined twins joined at the back of the head

Those are just a few. You can do your own research for more.
