BLACK LIVES MATTER
BLACK LIVES MATTER FOR AT THE VERY LEAST, THESE 10 REASONS...
African-American inventors have changed the world in many ways, some more so than others.
The advances made by African-American inventors are often overlooked, despite the profound impacts that they have made across the globe.
Still, these creations are essential to the way that the world has developed.
Below are 10 inventions by African-American inventors, listed in chronological order, that have left their mark on history and society.
1) Potato Chips
Inventor – George Crum
Created in August 24, 1853
As the story goes, Crum invented the potato chip as a reaction to an angry customer at a restaurant in which he worked as a chef. Since then, this snack has become popular around the world and defined, to an extent, the very nature of snack foods.
It may not appear to be a world-changing invention, though its creation has led to the development of a billion dollar industry that spans the globe.
2) Carbon-filament Light Bulb
Inventor – Lewis Latimer
Patented in January, 1881
Though Thomas Edison may be credited with creating the first light bulb, it was Latimer who made it practical enough to be used in everyday life.
The carbon-filament made light bulbs cheaper to produce and more efficient, leading to the rise of their popularity.
Without this invention, the world might be a much darker place to live in.
3) Gas Mask
Inventor – Garrett A. Morgan
First used in 1916
Morgan was a contentious individual whose inventions were often aimed towards saving lives.
The gas mask is one that, since first being introduced in 1916, has been utilized by emergency personnel everywhere to keep them safe in dangerous situations.
It was also heavily used during the chemical gas attacks of WWI, saving thousands of lives on the front line.
4) The Traffic Signal
Inventor – Garrett A. Morgan
Created in 1923
In a world that was quickly becoming filled with cars, Morgan’s traffic signal design was a revolutionary step forward in the field of traffic control.
His original model was a simple “stop” and “go” system which required hand-cranking to operate.
Though this design never saw widespread use, it was subsequently improved upon and led to the complicated and efficient system that is used in America today.
5) Blood Banks
Inventor – Dr. Charles Richard Drew
Established in 1940
Drew’s original research was in the separation and storage of plasma for easier and more efficient use.
He developed a method which allowed plasma to be dehydrated, enabling the practical formation of blood banks.
This process became very important for treating wounded soldiers during WWII and has since saved countless numbers of lives.
6) Automatic Refrigeration Systems
Inventor – Frederick M. Jones
Patented on July 12, 1940
Perhaps one of the most unnoticed inventions which have changed the shape of the world, the development of refrigeration systems for long-haul trucks, railroad cars and ships has become an essential part of the world’s infrastructure.
Without this invention, food and other goods which can spoil would not be shippable in the same regard as they are and the modern-day supermarket would cease to exist.
7) Electroacoustic Transducer Electret Microphone
Inventor – James E. West
Patented in 1962
The invention of this microphone is one that would signal the birth of the way communication is handled in the modern age.
It was used primarily in telephones, though has since come to fill many other niches in acoustic technologies, being refined and improved upon for half a century.
An estimated 90% of microphone designs today are based on West’s original design.
8) Closed-circuit Television Security System
Inventors – Marie Van Brittan Brown and Albert Brown
Patented in 1966
Though the original design could be seen as quite archaic compared to what is used today, the concept of closed-circuit security has had a major impact on the way the world functions.
In addition to becoming a major factor in how police investigations are performed, the rise of camera-based security both at home and in public places has taken permanent root, inspiring both the fear of “Big Brother” and the comfort of knowing that one is protected.
9) Far-Ultraviolet Camera and Spectrograph
Inventor – George Carruthers
Patented in November 11, 1969
The invention of this device was a great boost to the progression of astronomical science and observation.
The far-ultraviolet camera and spectrograph enable scientists to view ultraviolet activity in the Earth’s atmosphere and in other space phenomena.
Carruthers was a pioneer of NASA R&D, and his invention made its way to the moon aboard the Apollo 16 in its 1972 launch. Without this device, much of what is understood about space today would not be the same.
10) Laserphaco Probe and Cataract Surgery Procedures
Inventor – Dr. Patricia Bath
Completed in 1986
Dr. Patricia Bath was dedicated to her work of dealing with and finding ways to alleviate visual problems.
The Laserphaco, along with its methods of operation, revolutionized cataract surgery, making it a safer and more viable option for sufferers. This invention formed the basis for cataract surgery technologies that are used up to this very day.
It is the devotion to innovation and the need to help people which acted as inspiration to several of these inventions, as well as countless others.
