13 things that were invented much earlier than we think & nbsp

Vaccination (1796)
Edward Jenner created the first vaccine before the start of the 19th century. The vaccine was introduced in the infancy stage of the vaccinia virus, which was designed to eradicate smallpox that affected humans.

A milkmaid, Sarah Nelmes, came to Jenner with inflammation in her hands caused by smallpox. Jenner took the liquid from them, and then introduced it under the skin of an eight-year-old boy, his first experimental subject.
At first, his temperature rose, but the disease quickly disappeared. Jenner later introduced the boy with smallpox virus and found that he had developed immunity.
Battery (1800)
March 20, Volta's battery, developed by Italian inventor Alessandro Volta, will celebrate its 216th birthday.

Volta first called the invention "an artificial electric organ." This was due to the popular theory at that time, according to which animal tissue was needed to conduct electric current.
Instead, Volta used folded metal disks and rags soaked in saline. They conducted electricity, and so the battery appeared.
Microphone (1876)
Shortly after Alexander Bell presented his invention of the telephone, the German clerk Emil Berliner realized that the device’s transmitter was rather weak.

With only basic knowledge of electricity, Berliner set to work on a so-called free-contact transmitter that amplified the sound coming from Bell's existing phone model.
Bella's company, the American Bell Telephone Company, was so impressed with the work of Berliner that she made him an employee of her laboratory.
Dishwasher (1886)
In 1886, a few days after Christmas, Josephine Garis Cochran filed a request with the US Patent Office. Here's what the design she wanted to register looked like: a lot of compartments, suitable in size for plates and cups, were located inside a wire cage with a spinning wheel that sprayed hot soapy water onto dirty dishes.
Cochran founded a company to produce his invention, which later became known as Kitchenaid.

Contact lenses from the late 19th century were made of glass and completely covered the eyes. At first they were called "scleral lenses", emphasizing the connection with the eye protein. Contact lenses were invented by the manufacturer of artificial eyes F.A. Muller.
Escalator (1891)
Mechanization of stairs began on the threshold of the 20th century thanks to New York inventor Jesse Renault. The first Renault escalator model was installed on the Old Iron Pier on Coney Island. The invention quickly gained popularity among the miners and factory workers of the era of the industrial revolution, who could save energy during a long journey to work.
Car Radio (1919)
A. H. Grebe, a New York-based radio station maker, tested an early version of car radio, which became an important part of the nascent auto culture of the 1920s.

The Grebe device included a vacuum tube in the back seat, a small motor to power it, and a separate battery to power the radio itself.

Artificial Heart (1961)
With the help of Dr. Henry Heimlich, comedian and ventriloquist Paul Winchell filed a patent for the world's first artificial heart in 1961. The device included a small battery pack that needed to be worn on the body, and an internal pump controlled by it.
Although Winchell's concept was approved two years later, it was not until 1982 that the invention of Dr. Robert Jarvik was successfully implanted for the first time in humans.
Drone (1964)
The first unmanned aerial vehicle was the Lockheed D-21B. In the photo below, this is the smaller of the aircraft.
Between 1969 and 1971, he conducted reconnaissance missions in enemy airspace over China, but was later recalled, as he often fell, and President Nixon introduced more intelligent satellites to take photographs.

Internet (1969)
Shortly before midnight on October 29, 1969, engineers from the University of California at Los Angeles sent the word LOG to the Stanford Research Institute one letter at a time on the new ARPANET. It was a primitive system, but it contained the basic components that ultimately created the Internet in the form in which we know it.
Mobile Phone (1973)
Motorola researcher Martin Cooper invented the very first mobile phone model. The prototype offered only 30 seconds of conversation and required 10 hours of charging. Not to mention the fact that he weighed almost 2.5 kg.
GPS (1978)
Navstar 1, the first satellite to reach orbit, did this on February 29, 1978. It has long been withdrawn from orbit, but has helped the world enter a new era of communications. Thanks to the launch of 1978, we can swear on phones for too insistent directions.

MP3 player (1979)
Two decades before Apple introduced the iPod, British inventor Kane Kramer filed a patent for a digital audio player, which he called IXI. The device was the size of a pack of cigarettes, had a four-button control system and could hold about three and a half minutes of music.
“In seconds,” the application read, “a live performance at Carnegie Hall can be recorded and presented in stores around the world.”
