black people who invented things
Black inventors have created and improved many everyday things—from traffic lights and home security systems to refrigerated trucks, cataract lasers, and caller ID.
Black People Who Invented Things (Quick Scoop)
Everyday things you probably use
Here are some Black inventors whose work quietly shapes daily life:
- Garrett Morgan – Invented an early three‑position traffic signal and a “safety hood” that became a model for gas masks, improving both road safety and industrial rescue work.
- Alexander Miles – Patented automatic elevator doors that closed and opened without people having to pull or push them, making elevators far safer.
- Frederick McKinley Jones – Developed portable refrigeration systems for trucks, trains, and ships (Thermo King), which made it possible to ship fresh food and protect blood and medicine over long distances.
- Thomas L. Jennings – First African American to receive a U.S. patent; created “dry scouring,” a forerunner of modern dry cleaning for delicate clothing.
- Alice H. Parker – Designed a natural-gas–powered central heating system that inspired safer, more efficient modern home heating.
- Marie Van Brittan Brown – Co‑invented one of the first home security systems with cameras, peepholes, and an alarm, a foundation for modern home surveillance tech.
- Lonnie Johnson – NASA engineer who invented the Super Soaker water gun and holds numerous patents in energy and engineering.
- Mark Dean – Computer engineer instrumental in developing the color PC monitor and key IBM PC architecture, helping shape how modern computers work.
These inventions sit behind things like apartment elevators, grocery store supply chains, dry cleaners, home alarms, and even kids’ toys.
Earlier trailblazers
Long before today’s tech, Black inventors were pushing boundaries under far harsher conditions.
- Thomas L. Jennings (1791–1856) – Used profits from his dry‑cleaning patent to support abolitionist causes and help free family members from slavery.
- Henry Blair – One of the earliest Black patentees; designed seed planters that reduced the labor of farming.
- Lewis Latimer – Improved carbon filaments for light bulbs and worked on telephone technology, making electric lighting more practical and longer‑lasting.
Despite obstacles, their patents placed Black inventors directly into the heart of 19th‑century industry and infrastructure.
Modern and recent innovators
Black inventors today are active in software, health tech, clean energy, and entertainment technology.
- Marian Croak – Holds hundreds of patents in internet and voice‑over‑IP technologies and pioneered text‑to‑donate systems widely used in disaster relief campaigns.
- Tahira Reid Smith – Invented an automated Double Dutch jump‑rope machine, blending engineering with play and education.
- Monique Dyers – Developed software tools that make solar power more accessible for underserved communities.
- Greg Smoot (Disney special‑effects inventor) – Helped create new theatrical technologies and special effects for theme parks, earning induction into the National Inventors Hall of Fame’s 2024 class.
These creators work on everything from remote work infrastructure and telehealth to greener energy access and immersive entertainment.

Why this is trending again
Each Black History Month, there’s renewed focus on “black people who invented things,” as people highlight how much of modern life relies on inventions that weren’t always properly credited to Black creators. Recent articles in 2024–2025 are pushing to connect that history with today’s issues, from climate and health inequities to digital access, and to show Black ingenuity as central to solving current problems, not just a historical footnote.
“Countless inventors of color have gone largely unrecognized, and some are completely lost to history.”
TL;DR: From traffic lights and refrigerators in trucks to home security systems and the tech behind internet calls, Black inventors have been central to how the modern world runs—often without getting full credit at the time.
