27 Black Inventors Who Made Life Easier

Percy L. Julian, an African American inventor, once said, “I have had one goal in my life, that of playing some role in making life a little easier for the persons who come after me.” As the holder of 130 patents – including industrial chemicals used in firefighting – Julian, who died in 1975, certainly has made a difference in society. 

He is just one of a wealth of Black inventors – some of them former slaves or the sons or daughters of slaves – whose devices, inventions, processes, and innovations have made our lives better. To compile a list of some of them, 24/7 Tempo consulted numerous sources including History, Biography, Parents, and Invent (the website for the National Inventors Hall of Fame).

Many of the creations of these inventors were new devices or improvements on existing ones found in the home. These include the portable ironing board, the dustpan and the eggbeater. To maximize space in small apartments, one woman created a bed that could fold into a cabinet. For greater convenience, a man reduced treks to the post office by inventing the street letter box.

A Black inventor developed a refrigeration system in long-haul trucks that revolutionized the grocery industry. Others invented ways to improve safety outside the home, such as the three-way traffic light and automatic doors on elevators. An African-American’s development of a process for separating plasma from blood, allowing it to be stored for up to a week, has helped save countless lives. (Here are 30 NASA inventions we still use today.)

George Edward Alcorn Jr. (1940- )
> Notable invention: X-ray spectrometer

A physicist who worked at NASA, George Edward Alcorn Jr. played a role in revolutionizing astrophysics and semiconductor manufacturing. He’s best-known for creating an X-ray spectrometer, which he patented in 1984, used to analyze galaxies and other aspects of space. His research into plasma etching is still used in the production of semiconductors. Acorn has received eight patents in all for his work.

Dr. Patricia Bath (1942-2019)
> Notable invention: Laser cataract treatment device

In 1988, Dr. Patricia Bath became the first Black doctor to receive a medical patent – for a laser cataract treatment device called Laserphaco Probe. The device is used in cataract surgery and has helped improve the eyesight of millions of people.

> Notable invention: Improved portable ironing board

Sarah Boone, born into slavery, took Elijah McCoy’s invention of the portable ironing board and improved it in 1892. Her ironing board featured a narrower, curved design, making it easier to iron women’s clothing. The modern ironing board resembles Boone’s design.

Marie Van Brittan Brown (1922-1999)
> Notable invention: Early video home security system

Marie Van Brittan Brown and her husband, Albert Brown, invented an early home security system. Marie was inspired to develop the system when she was working as a nurse and didn’t feel safe at home in Queens at night, especially when her husband was not home. Her name appeared above her husband’s on the patent granted for the invention, which was the first closed-circuit television security system and became the model for most such systems today.

George Washington Carver (1864-1943)
> Notable invention: Developed methods to prevent soil depletion

Perhaps the most famous inventor on this list is Carver, an agricultural scientist who devised various uses for peanuts, sweet potatoes, and other crops that would combat soil depletion and improve farmers’ yields. He also developed numerous products based on the peanut – among them soap, face powder, mayonnaise, shampoo, and metal polish – and is credited with having inspired the organic farming movement in the South.

Mark Dean (1957- )
> Notable invention: Color IBM PC monitor and gigahertz chip

Before flat screens and high-definition LCD monitors, personal computer displays had no color and connected to computers with limited processing power. Mark Dean helped change that. An engineer at IBM who helped create that company’s first PC, Dean led the team that developed the color monitor and the first gigahertz processor. The latter device allows for higher processing rates at faster speeds in PCs.

Charles Drew (1904-1950)
> Notable invention: Means of separating plasma from blood

Charles Drew invented a process of separating plasma from blood, allowing it to be stored for up to a week, far longer than had been possible. He worked with the American Red Cross during World War II, but resigned to protest the organization’s policy of segregating blood from white and Black donors.

Sarah E. Goode (1855-1905)
> Notable invention: Folding cabinet bed

In 1885, Sarah E. Goode became one of the first Black women in the U.S. to receive a patent. Her invention: a folding cabinet bed. Goode and her husband ran a furniture store and to maximize space for her customers who had small apartments, she invented a bed that when folded, could be tucked away inside a roll-top cabinet.

Joseph Hawkins (Unknown)
> Notable invention: Improved gridiron

A gridiron was a metal rack attached to a handle used to cook meat over a campfire or in a fireplace. Hawkins developed an improved version for home cooking, receiving a patent in 1845. Hawkins’ invention has evolved into today’s metal oven racks that allow food to be cooked at varying temperatures.

Shirley Ann Jackson (1946- )
> Notable invention: Various telecommunications innovations

Shirley Ann Jackson, an American physicist and the first Black woman to graduate from the Massachusetts Institute of Technology, has had a hand in various telecommunications inventions, such as the portable fax, fiber optic cables, and caller ID. She has been inducted into the National Women’s Hall of Fame.

Thomas Jennings (1791-1856)
> Notable invention: Process for dry-cleaning delicate clothing

Thomas Jennings is believed to be the first African-American to have received a paten, awarded in 1821. Working as a tailor in New York City, he invented a process to dry-clean delicate clothes called “dry-scouring,” a forerunner of modern dry cleaning. Jennings became rich from his invention and used his money for the abolitionist cause.

Before the late 1940s, the only way for trucks to transport perishables was in containers filled with ice. Frederick McKinley Jones changed that by developing automatic refrigeration equipment that could be used on long-haul trucks. This revolutionized how grocery stores operated because they could sell products brought in from long distances.
