11 Famous Black Inventors Who Changed Your Life

The rich history of Black inventors in the United States likely begins before our current historical record captures. Even so, there’s plenty of noteworthy individuals who revolutionized the world with their creations.

In 1821, Thomas L. Jennings, who was emancipated from slavery, became the first Black inventor to be granted a U.S. patent. He opened the door for many other African Americans inventors—like Madam C.J. Walker, Frederick McKinley Jones, Patricia Bath, and Mark Dean—to similarly make their marks.

These 11 famous Black inventors developed ingenious products, machinery, and technology that continues to impact everyday life.

Thomas L. Jennings

The first African American U.S. patent recipient, Thomas L. Jennings was working as a tailor and businessman in New York City when he invented a process for dry-cleaning delicate clothing known as “dry-scouring.” Jennings applied for a patent in 1820 and received his history-making approval the following year. With the money he earned from his invention, the formerly enslaved person donated to abolitionist causes and even reportedly freed his still-enslaved family members.

Sarah Boone

In 1892, Sarah Boone patented a design improvement to Elijah McCoy’s ironing board. The North Carolina native wrote in her application that the purpose of her invention was “to produce a cheap, simple, convenient, and highly effective device, particularly adapted to be used in ironing the sleeves and bodies of ladies’ garments.”

Alexander Miles

Anyone who’s ridden modern elevators has Alexander Miles to thank for the stair alternative’s automatic doors. Prior to his design’s 1867 patent, riders had to manually open and close two sets of doors when entering and exiting elevator cars. If a passenger happened to forget to close one of the doors, subsequent elevator riders risked a potentially fatal fall down the elevator shaft. Because, as the adage goes, necessity is the mother of invention, Miles created a mechanism that forced both elevator doors to close simultaneously, thus preventing dangerous accidents.

Elijah McCoy

Of the 57 patents Elijah McCoy—reportedly the namesake for the popular, complimentary phrase “the real McCoy”—received over his lifetime, the portable ironing board might be one of the most timeless. As the story goes, having to iron on uneven surfaces frustrated his wife, Mary Eleanor Delaney, and so he created the ironing board to make her life a little easier. McCoy received the patent for this particular creation in May 1874. He is also the man behind another major invention beloved by homeowners: the lawn sprinkler.

Madam C.J. Walker

Philanthropist and entrepreneur Madam C.J. Walker was born to formerly enslaved sharecroppers and orphaned at just 7 years old. After later suffering hair loss from a scalp condition, Walker invented an innovative line of Black hair care products in 1905 that led to her distinction as one of America’s first self-made millionaires. Her highly successful cosmetics brand is still around today.

Garrett Morgan

Garrett Morgan was a prolific Black inventor whose early patent for an improved sewing machine design provided financial security for him and his family. The Kentucky native was also concerned about the welfare of others. His “safety hood,” patented in 1914, was a breathing device that filtered out harmful elements and became the prototype for the World War I–era gas mask. He also created a more sophisticated traffic signal by adding a warning light, similar to what we use on streets today.

Frederick McKinley Jones

Before Frederick McKinley Jones developed the automatic refrigeration equipment used in long-haul trucks that transport perishables in the late 1940s, the only way to keep food cold en route to delivery destinations was by using ice. Thanks to his invention, grocery stores were able to buy and sell products (many of which you probably purchase regularly) from far distances without the risk of them spoiling during transport. Jones’ technology was also used to transport blood during World War II.

Alice H. Parker

The central heating furnace design that Alice H. Parker patented in December 1919 made use of natural gas for the first time to keep homes warm and toasty. Inspiring her innovation: the limited efficiency of fireplaces (along with the smoke and ash they produce) during the cold winters at her Morristown, New Jersey, house. Many modern homes still employ a similar forced air heating system for which her idea was a precursor.

Marie van Brittan Brown

Another New York City resident, Marie Van Brittan Brown created an early version of the modern home security system. Feeling unsafe due to her neighborhood’s high crime rate, the full-time nurse rigged a motorized camera to record her home entryway and project images onto a TV monitor. Also included in her setup was a two-way microphone in order to communicate with visitors without opening the door, as well as a panic button to notify police of any potential emergency in progress. After filing to patent the closed circuit TV security system in 1966, Brown received her approval in December 1969.

Patricia Bath

A true visionary, Patricia Bath became the first Black female doctor to receive a medical patent when she invented a laser cataract treatment device called a Laserphaco Probe in 1986. It was one of several firsts the ophthalmologist achieved. The co-founder of the American Institute for the Prevention of Blindness patented her invention in 1988. Now used around the world, Bath’s device has improved sight for millions of people.

Mark Dean

We have Mark Dean to thank for several computer innovations that we might take for granted today. The color PC monitor (that you might be using right now) is just one of them. With more than 20 patents to his name, Dean also led the IBM team that created the first gigahertz chip, a groundbreaking innovation that can handle a billion calculations per second, and co-created a system to allow peripheral devices like monitors and printers to plug directly into computers.
