As a minority-owned business, JEM Engineering proudly celebrates Black History Month.
This month, we honor the impactful contributions made by African American engineers have made in STEM and American History. In this issue, we celebrate Granville Woods, Marie Van Brittan Brown, and Lewis Latimer by highlighting some of their many achievements.
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
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.
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.
In celebration of STEM Day (November 8) we asked our CEO, Nancy Lilly, and our Director of Antenna Development, Victor Sanchez, why they decided to pursue a career in STEM, and this is what they said…
Every product, specialty or off-the-shelf, must be designed, tested, and perfected by a team of experts, so that the end-user can be assured of its reliability. The same applies to antenna design.
Like with most products, an antenna’s outstanding performance in the field must be preceded by outstanding performance in the lab.
