Invention of the electric battery
Alessandro Volta, an Italian physicist known for his work in electricity, created the first forerunner of the electric battery, called a voltaic pile. The electric unit known as a "volt" was named in his honor. It is unknown exactly what month and day he created this, but we know what year. His birth month and day are in place of the those details of the voltaic pile's creation.

Invention of Braille
15-year-old Louis Braille, who became blind after an unfortunate accident, invented an ingenious way to read and write for the blind. This created an opportunity for even the blind to have an education. Again, it is unknown exactly what month and day he created this, but we know what year. His birth month and day are in place of the those details of the braille's creation. More information about braille at https://www.britannica.com/topic/Braille-writing-system -
Invention of the Fax Machine
Alexander Bain of England invented the earliest version of the fax machine. It consisted of two pens connected to pendulums, which joined to a wire that was able to write on an electrically conductive surface. Many variants of his original apparatus were created to the fax machine we know today. More information at https://faxauthority.com/fax-history/ -
(Patented) Invention of the Vacuum Cleaner
Daniel Hess seems to be the first patent-owner of the vacuum cleaner. The machine had a rotating brush like others at the time, however, the machine also had a mechanism on top of the body to generate suction. It incorporated two "water chambers" to capture the dust and dirt. The air was said to have been cleansed as it passed through the device.

Invention of the (Safe) Elevator
The elevator idea was invented earlier than 1852, at an unknown date. However, the safe elevator, one with breaks, was invented by Elisha Graves Otis. From there, he started the first elevator business and here we are, 165 years later! The patent for the elevator is the date shown.

Invention of the Typewriter
Christopher Sholes, Carlos Glidden and Samuel Soule invented the first practical mechanical typewriter machine in 1867, being patented in 1868. It was like the functional typewriter we see even today, but back then was a revolutionary advancement in the communicative aspect of society.

(Patented) Invention of the Lightbulb
The light bulb changed human life by illuminating the night and making it distributable to a wide range of human activities. The electric light, one we see the variants of, was invented in 1879 by Thomas Alva Edison. He was neither the first nor the only person trying to invent an incandescent light bulb, but was one of the "biggest" individuals to complete it.

Invention of the Refrigerator
Carl von Linde created the earliest form of refrigerators. His invention summarized is a continuous process of liquefying gases in large quantities, the basis of our refrigerators today. As one can imagine, this breakthrough changed the lives of millions across the globe. The dates shown are the times of patents for Lind's oxygen process and apparatus in the US.

Invention of the Microwave Oven
During World War II, the magnetron, a tube that produces microwaves, was created with/for the ability to spot Nazi warplanes on their way to bomb the British Isles. The idea of using microwave energy to cook food was accidentally discovered by Percy LeBaron Spencer when he found that radar waves had melted a candy bar in his pocket! It was marketed in 1954.
