Most people have heard about famous inventions like the light bulbthe cotton gin and the iPhone. But there are countless other, often overlooked inventions that make Who created black people daily lives easier. Among the creative innovators behind these devices are African American inventors. From the traffic light to the ironing board, see a list of products that have sprung from the minds of Black inventors. In the late 19th century, it was improved upon by Sarah Boonean African American woman who was born enslaved.

One of the first Black women in U. Before security systems became a fixture in homes, an African American nurse Mary Van Brittan Brown, devised an early security unit for her own home. She spent many nights at home alone in Queens, New York while her husband was away, and felt unsafe with high rates of crime in her neighborhood.

On top of that, police were unreliable and unresponsive. So she created a device that would help put her mind at ease.

InBrown invented a system that used a camera that could slide into and look through four peepholes in her front Who created black people. She added other features to the system, including a microphone to speak to anyone at the door, a button to unlock the door, and a button to contact the police. She and her husband took out a patent for the system in the same year, and they were awarded the patent three years later in Home security systems commonly used today took various elements from her de.

Watch a preview now. With only an elementary school education, Black inventor and son of an enslaved parentGarrett Morgan came up with several ificant inventions, including an improved sewing machine and the gas mask.

However, one of Morgan's most influential inventions was the improved traffic light. Morgan's was one of the first three-light systems that were invented in the s, resulting in widespread adoption of the traffic lights we take for granted today.

Thanks to the successes of his other inventions, Morgan bought and car and, as a motorist, he witnessed a severe car accident at an intersection in his city of Cleveland, Ohio. He took out the patent for the creation inand it was granted to him the following year.

If your refrigerator has any produce from your local grocery store, then you can credit African American inventor Frederick McKinley Jones. He received a Who created black people for his invention inand co-founded the U. Thermo Control Company, later known as Thermo King. The company was critical during World War IIhelping to preserve blood, food and supplies during the war.

The use of elevators in everyday life keeps people from committing to long and grueling climbs up several flights of stairs. However, before the creation of elevator doors that close automatically, riding a lift was both complicated and risky. Before automatic doors, people had to manually shut both the shaft and elevator doors before riding.

Forgetting to do so led to multiple accidents as people fell down elevator shafts. As the story goes, when the daughter of African American inventor Alexander Miles almost fatally fell down the shaft, he took it upon himself to develop a solution. In he took out a patent for a mechanism that automatically opens and closes elevator shaft doors and his des are largely reflected in elevators used today.

And the vast majority of microphones used today, including the microphones used in phones and cameras, use a microphone co-invented by a Black man. James E. West was tasked with creating a more sensitive and compact microphone while working at Bell Labs in Along with his German colleague Gerhard Sessler, West invented the foil electret microphone, which was considerably less expensive to produce than the typically used condenser microphones.

Two years after it was invented, the final model of the microphone was developed and in they patented Who created black people landmark invention. Only four years later, the new microphone was in wide production and was being Who created black people in hearing aids, tape recorders, most telephones and baby monitors. The light bulb itself was invented by Thomas Edisonbut the innovation used to create longer-lasting light bulbs with a carbon filament came from African American inventor Lewis Latimer.

Latimer, the son of formerly enslaved people, began work in a patent law firm after serving in the military for the Union during the Civil War. He was recognized for his talent drafting patents and was promoted to head draftsman, where he co-invented an improved bathroom for railroad trains. His successes would garner him further attention from the the U. Electric Lighting Company, putting him at a company in direct competition with Edison, in While there, Latimer patented a new filament for the light bulb, using carbon instead of more incendiary materials, like bamboo, that were commonly used for filaments.

The addition of the carbon filament increased the life span and practicality of light bulbs, which had ly died after just a few days.
