Discover the inventions by Black innovators that changed the world and are still shaping our lives today.
Garrett Morgan · 1923
The three-position traffic signal added a 'warning' position between stop and go, which is the yellow/amber light used today. Before this invention, traffic signals only had two positions: stop and go.
"Morgan's design became the foundation for all modern traffic lights, preventing countless accidents at intersections worldwide."
Lewis Latimer · 1882
Latimer developed an improved method for making carbon filaments for the Maxim electric incandescent lamp. His filament was more durable and longer-lasting than previous designs.
"Made electric lighting affordable and practical for everyday use, enabling the widespread electrification of homes and businesses."
Alexander Miles · 1887
Miles patented an improved elevator design with automatic opening and closing doors. Before this invention, elevator doors had to be manually opened and closed, creating dangerous open shafts.
"Made elevators safe for widespread public use, enabling the construction of tall buildings and modern cities."
George Washington Carver · 1916
Carver developed over 300 products from peanuts, including dyes, plastics, gasoline, cosmetics, medicines, and foods. He also created over 100 products from sweet potatoes.
"Transformed Southern agriculture by offering alternatives to cotton, preventing soil depletion and providing economic opportunities."
Madam C.J. Walker · 1905
Walker developed a line of cosmetics and hair care products specifically designed for Black women, including her famous 'Wonderful Hair Grower' formula.
"Created an entire industry, employed thousands of Black women as sales agents, and proved that Black entrepreneurship could thrive."
Garrett Morgan · 1914
Morgan's 'National Safety Hood' was a breathing device that filtered out smoke and provided fresh air. It was the precursor to the modern gas mask.
"Saved the lives of firefighters and soldiers in World War I. Morgan used it himself to rescue workers trapped in a tunnel explosion in 1916."
Granville T. Woods · 1887
The Synchronous Multiplex Railway Telegraph allowed messages to be sent between moving trains and train stations, dramatically improving railroad safety.
"Prevented countless train collisions by allowing communication between moving trains for the first time."
Elijah McCoy · 1872
McCoy's automatic lubricating cup allowed steam engines to be lubricated while running, eliminating the need to stop trains for manual oiling.
"Revolutionized industrial machinery efficiency. His device was so superior that buyers asked for 'the real McCoy,' coining the famous phrase."
Jan Ernst Matzeliger · 1883
Matzeliger's machine automated the process of attaching the upper part of a shoe to its sole (lasting), which was previously done by hand.
"Reduced shoe prices by 50% and increased production from 50 to 700 pairs per day, making shoes affordable for ordinary people."
Lonnie Johnson · 1989
The Super Soaker uses a pressurized air system to shoot water at high velocity. Johnson invented it accidentally while working on a heat pump system.
"Became one of the top-selling toys of all time with over $1 billion in sales, and funded Johnson's research into clean energy technology."
Mark Dean · 1981
Dean co-created the IBM PC and developed the ISA bus, which allowed peripherals like printers, modems, and keyboards to be connected to the computer.
"The IBM PC became the standard for personal computing, fundamentally changing how the world works, communicates, and accesses information."
Sarah Boone · 1892
Boone's improved ironing board featured a narrower, curved shape ideal for pressing sleeves and women's garments. Her design was a significant improvement over flat wooden boards.
"Her design became the standard for modern ironing boards used in millions of homes worldwide."
Patricia Bath · 1986
The Laserphaco Probe uses laser technology to vaporize cataracts quickly and painlessly, then irrigates and cleans the eye before inserting a new lens.
"Revolutionized cataract surgery worldwide, making it less invasive and more precise, restoring sight to people who had been blind for decades."
Otis Boykin · 1964
Boykin invented a control unit for the pacemaker that uses electrical impulses to regulate the heartbeat. His improved electrical resistor also made computers and electronics more reliable.
"The pacemaker control unit has saved millions of lives by helping regulate heartbeats in patients with cardiac conditions."
Charles Drew · 1940
Drew developed techniques for long-term preservation of blood plasma and established the first large-scale blood bank program during World War II.
"Drew's blood banking innovations saved thousands of lives during WWII and established the modern blood transfusion system used worldwide."
Granville T. Woods · 1893
Woods developed the third rail system for distributing electrical power to electric streetcars and subway trains without overhead wires.
"The third rail system is still used in subway systems worldwide, including in New York, London, and many other cities."
