Granville Woods | Black History Month 2021 | JEM Engineering

Granville Woods

1856-1910

Woods was the first African American mechanical and electrical engineer after the Civil War. He held over 60 U.S. patents, including the steam boiler furnace, the automatic break, the safety dimmer and the egg incubator. Additionally, Woods improved numerous inventions, including the safety circuit, telegraph, telephone, and phonograph.

Marie Van Brittan Brown

1922-1999

Together with her husband, Albert, Brown invented the first closed-circuit television security system in 1966. This invention included a radio-controlled wireless system that could stream the video to any television in the house. Along with the video system, the Browns created a two-way microphone system that would allow for communication between the residents and the person at the door. Additionally, Marie created a system to unlock the door remotely. Her invention is the predecessor to the modern-day security systems, used in both residential and commercial spaces.

Lewis Latimer

1848-1928

Latimer was the patent draftsman for several inventions, including the incandescent light bulb. Patented the “Process of Manufacturing Carbons”, an improved method for the production of carbon filaments for lightbulb. He also developed a forerunner of the air conditioner called “Apparatus for cooling and disinfecting.” Latimer was the first African American to join the Edison Pioneers.
