21. Norbert Rillieux (1806-1894)
Notable invention: Multiple-effect evaporator
This American engineer revolutionized the sugar industry with the multiple-effect evaporator, a device that produced high-quality sugar and reduced production costs by using steam efficiently to evaporate water and prevetn sugar from burning or being discolored. After patenting his creation in 1843, sugar manufacturers from Cuba to Egypt requested Rillieux’s machine. It’s still used today to make glue, soap, milk, and other products. Sweet.
20. Andrew Jackson Beard (1849 – 1921)
Notable invention: The Jenny Coupler
Before the Jenny Coupler, railroad cars were manually joined together. As one of the many railroad workers who lost a limb (his leg) in a coupling accident, Beard saved many lives with his invention, which automatically locked two car-bumps together. He patented the device in 1897, the same year Congress created the Federal Safety Appliance Act, a law that made it illegal to operate railroad cars without automatic couplers. Not bad for a man with little to no education in engineering.
19. Lewis Howard Latimer (1848–1928)
Notable invention: Water closet
Before serving as Thomas Edison's original draftsman and sketching invention plans for Alexander Graham Bell, Latimer was best known for improving the railroad toilet system with the water closet. For those brand new to 18th and 19th century jargon, it's a flush toilet. He would also create a method to make carbon filaments for the electric lamp and become the only African American member of the engineering division at the Edison Company. Makes you wonder if Edison stole borrowed any ideas from him.
18. Meredith Gourdine (1929–1998)
Notable inventions: The Incineraid system, Focus Flow Heat Sink, and industrial paint spray
Gourdine has been praised as a pioneer researcher and for creating electrogasdynamics—the generation of electrical energy from the conversion of the kinetic energy contained in a high-pressure, ionized, moving combustion gas.

16. Garrett Morgan (1877–1963)
Notable inventions: Three-way traffic signal, hair straightener
After witnessing a traffic collision, Morgan decided to build a non-electric three-way traffic signal that featured Stop, Go, and all-directional stop positions. He would create another safety-inspired device, the gas mask, which he used to save 32 men trapped during an explosion in an underground tunnel in Lake Erie. The man even invented the first human-hair straighetner and sold it under the name G.A. Morgan Hair Refining Cream.
15. Granville T. Woods (1856–1910)
Notable inventions: Telegraphony, trolley conducting system, third brake, and improved air brake
The self-taught inventor managed to combine the telephone and telegraph to form the telegraphony, a system used to send voice and telegraph messages over a single wire. His other most notable invention was a detection system that informed train engineers of how close their trains were to collision. He also received credit from a few historians for inventing the third rail, which Thomas Edison was awarded a patent for 10 years earlier in 1882. Now we know why they referred to him as the “Black Edison.”
14. David N. Crosthwait, Jr. (1898-1976)
Notable inventions: Heating systems for huge buildings, vacuum pump, automobile turn signal, and thermostat control
An expert in central air conditioning and heat ventilation systems, Crosthwait took his knowledge of electrical engineering and built everything from vacuum pumps to temperature regulating devices. He would go on to accomplish one of the biggest feats of any 20th century inventor—creating the heating systems for Rockefeller Center and Radio City Music Hall. Someone was in an empire state of mind.
13. Roscoe L. Koontz (1922–present)
Notable inventions: Collimator and pinhole gamma ray camera
This health physics specialist created the collimator, a device used to align two or more devices and set toward at a proper focus. He also designed radiation activity measuring devices and automatic air and water sampling equipment.

Notable inventions: Electrical resistor, variable resistor, control unit for heart stimulators, burglar-proof cash register, and chemical air filter
Inventor of over 25 electronic devices, Boykin’s biggest contribution to the tech field would be the control unit for the artificial heart pacemaker, which used electrical impulses to maintain a steady heartbeat rate. Other big accomplishments would include the creation of the variable resistor (used in guided missiles) and the improved electrical resistor used in computers, radios, and TVs.
9. Henry Blair (1807–1860)
Notable inventions: Seed planter and cotton planter
Very little is known about Henry Blair’s background, but we do know that he invented the seed planter, a machine that allowed farmers to plant corn faster with less work. It’s also been documented that he was the second black inventor to ever be rewarded a patent for his work and was the only inventor to be identified as “a colored man” according to Patent Office records. Blair signed each patent by marking an “x” as his signature because he couldn’t write.
8. Richard Spikes (1884–1962)
Notable inventions: Railroad semaphore, multiple barrel machine gun, beer-keg tap, self-locking rack for billiard cues, automobile directional signals, automatic gear shift, and automatic car washer
Is there anything this guy didn't invent? The San Francisco native is most famous for developing a turn signal system for vehicles, but was never awarded a patent for it. Percy Douglas-Hamilton was bestowed the honor in 1907. Spikes might of gotten the better end of the stick, as his transmission and gear-shifting designs helped him score over $100,000 during the 1930s. Dedicated to his work, Spikes worked on the automatic safety brake until he went blind and died in 1962.
7. Elijah McCoy (1844–1929)
Notable invention: Lubricating cup
Having worked as an oilman on a steam engine locomotive, McCoy combined his education and work experience to create a lubrication system that greased up engines and machines without having to shut them down. This would help reduce transportation times for all steam engine-based trains. As the story goes, his invention was so good, railroad engineers, trying to avoid shotty products, would ask if locomotives were outfitted with "the real McCoy". In addition to the lubricating cup, McCoy also held 57 patents.
6. John Henry Thompson (1959-present)
Notable inventions: Lingo programming and XObjects
Known as the “Father of Lingo Programming", Thompson developed the popular scripting language to help render visuals in computer programs.
