15 Inspiring Black Inventors Who Changed The World For The Better

An inventor is someone who discovers a new device, method or any other means from which, most of the time, the humanity is greatly benefited. Despite the decades of torture and slavery, few black, African-American inventors have succeeded in their quest to do the same. With the help of the following list, we tried to pay homage to those inventors who are either forgotten or lesser known, without whom we would certainly miss a few important things in our daily life. Below are the 15 greatest black inventors that changed the world with their minds.

15. Lonnie Johnson

Contribution: Super Soaker Gun (toy)

Have you ever played with the Super Soaker? I am sure you did, but do you know who invented it? The idea of a pressurized water toy/gun was first conceived by a NASA and US Air Force engineer Lonnie Johnson. After formulating the water gun, he applied and successfully received a US patent in 1986. Since then Lonnie Johnson has more than 80 patents for his various inventions.

The Super Soaker became an instant hit on the markets, generating more than $200 million in sales in 1991. Shortly after that, he devices other improvements and upgrades to the Super Soaker. In 2013, Hasbro Inc., the legal owner of Lonnie Johnson’s invention paid him $73 million of due royalties.

14. Jan Ernst Matzeliger

Contribution: Shoe making machine

Jan Ernst Matzeliger was born in Paramaribo, the capital city of Dutch Guiana, where his father operated the Colonial Shipworks. At the age of 19, he left his home to work on a merchant ship of the Dutch East Indies company and then settled in Philadelphia, USA. It was during this time he learned about the shoe trade and made his mind that he will dedicate his life to this industry.

After nearly five years of tireless work and dedication, Matzeliger was finally able to obtain a US patent for a shoe making machine that could produce from 200 to 700 pairs of finished shoes in a single day. But the success came at a price. He used to work days and hours without eating food which later caused him some serious health problems. Matzeliger died of tuberculosis in 1889.

13. Elijah McCoy

Contributions: Improvements in refrigeration

We sure love cheese and other dairy products, but it wouldn’t be available to us if weren’t for this man, Frederick McKinley Jones. In 1935 he fabricated a revolutionary portable air-cooling unit for trucks and vehicles carrying diary and other perishable food, for which he received a patent in 1940. Based on his success he cofounded Thermo King Corporation, a temperature control unit company for trucks.

During his lifetime, he claimed a total of 61 patents, mostly for his portable refrigeration machine, while other are for portable X-ray machines, sound equipment, and gasoline engines. Jones became the first person of African heritage to be elected into the American Society of Refrigeration Engineers in 1944 and in the 1950’s he was appointed as a consultant to the Bureau of Standards and US DOD.

11. George Washington Carver


Contribution: Alternative crops technique

Mr. George Carver was born to a poor slave family in Missouri. In spite of his poor economic status, he was able to get a quality education, which was unsurprisingly restricted to the African-Americans at that time. He completed his masters from the Iowa State Agricultural Collage in botany.

After completing his studies, he went on to work for a company, where he assigned improve agricultural conditions of a land in southeastern Alabama. There he implemented various crop rotation techniques which helped farmers to improve their crop yield while maintaining the soil potency at the same time.

10. Thomas L. Jennings

Contribution: Dry Scouring

After receiving a patent for his “dry scouring” process, which was used for cleaning cloths, from New York he became the first African-American person to get a patent under his own. After being born in a free black family, Jennings successfully operated a tailor and dry cleaner business. Sometime in the year 1821, he came up with a quite unique cleaning process, for which he was granted a patent.

9. Lewis Howard Latimer

Contributions: An improved toilet system, Improved method for producing carbon filaments

After running away from his master, and a short employment in the United States Navy,  Lewis Howard Latimer became an employee of a patent law firm. Here he learned patent law and soon became one the finest draftsmen in the business. Along side his role in famous patent fillings such as Bell’s telephone and Edison’s bulbs, he is also known for several inventions. One of such invention was an enhanced process of manufacturing carbon filaments which were used in lightbulbs.

7. Marie Van Brittan Brown

Contribution: Home security systems

Can you imagine your home, office space without surveillance systems? I think we all know the answer to that. And that’s what Mari Van Brittan Brown, an African-American inventor thought before coming up with a concept of security system, where cameras can be used to monitor every movement outside her house.

What started as a gadgetry, only for domestic use, quickly became popular in workplaces as small and big companies started using the same concept of surveillance on their properties. While her original idea consisted of just a camera, a monitor and a microphone (two-way) and several peepholes, it certainly inspired today’s sophisticated security mechanisms. For her ingenious invention, Brown was awarded by the National Science Committee.

6. Patricia Bath

Contributions: Laserphaco Probe (used for treating cataracts)

Born in Harlem, Manhattan Dr. Patricia Bath is the first female doctor to acquire a product patent for medical purpose. In 1981, she devised a medical instrument known as Laserphaco Probe, which increases the performance of laser devices  during cataract operations. The device quickly became a standard to treat cataract condition which is now internationally used. She currently holds four different patents related to this device.

5. George Robert Carruthers

Contribution: Ultraviolet spectrograph

George Robert Carruthers is an African-American physicist and inventor, who spent most of his time in U.S Naval Research laboratory in the US capital. While working for the U.S NRL, he devised the far ultraviolet spectrograph/ camera, which was effectively used in the Apollo 16 mission. Before this, Dr. Carruthers invented an electromagnetic Image converter,” for which he received his first patent.

In 2013, he was awarded with the National Medal of Technology of 2012, by former US president Barack Obama. Robert Carruthers is currently an honorary member multiple scientific societies, including the American Astronomical Society, the American Institute of Aeronautics and Astronautics (AIAA), the American Geophysical Union, and the National Society of Black Physicists.

4. Otis Boykin

Contribution: Various electrical resistors and control unit of cardiac pacemaker

Otis Frank Boykin was born in Dallas, Texas, to an average family. During his lifetime, he acclaimed 28 different patents. One of his early inventions was an improved electrical resistor which is used in computers, television and other electronic devices. Otis Boykin lost her mother due to heart failure, when he was just over a year old, which inspired him to device CU of an artificial pacemaker.

3. Annie Malone


Contribution: Cosmetics and Hair care products

Annie Malone was an American inventor and a businesswoman, who curated one of the most successful commercial product line of cosmetics especially for the needs of African-American women. Her childhood interest in both chemistry and hair care lead her to develop her own line of hair care products.
