Important inventions, wrongly “attributed” to Thomas Edison. Photo

Controversial person in history.

Thomas Edison is considered one of the greatest inventors of all time. But is it really? Edison hired people specifically that they were engaged in the inventions that he later appropriated. While he was paying these people a pittance. Read about the bulb and other things that Edison actually didn’t invent.

1. Camera

In the 1890s Thomas Edison received a patent for the kinetoscope or film, based on the work on subject pictures Joseph made by nicéphore niépce and Louis Daguerre, and the first movie camera, created by Edward Meybridzha in 1977. Edison also saw the invention of the peep show, the technology for displaying moving images. A large part of the work was done by William Dickson, assistant to Edison.

2. Bulb

In fact, the first light bulb with a carbon filament invented by the British scientist Joseph Swan and Edison only perfected.

3. Electric chair

It was invented by one of his employees, Harold P. brown. And Edison promoted the invention, therefore, his name is closely associated with the advent of the electric chair. Brown used the alternating current voltage and design, based on the design of the chair is George Westinghouse. Simultaneously with the funding of the invention of Edison brown publicly criticized Westinghouse, claiming that his invention of cruel, but also opposed the death penalty. As a result, the brown chair was used in new York state for the death penalty in 1890

4. Gramophone

Despite the fact that Edison was credited with the invention of the phonograph, it’s actually not. But he invented the recording machine. Of course, attempts to record sound was being produced from the 1850s, but the invention of the phonograph was a breakthrough.

5. Battery

Edison was not the first who invented the battery – Alessandro Volta did it for decades before him. But he turned this invention into a profitable business. He worked hard to ensure that batteries can be used in cars, but could not develop a battery that would have covered the needs of the growing automotive industry. But later his batteries were used in industrial needs.

6. Wax paper

Wax paper probably invented in 1851 by Gustave Le gray, and not Thomas Edison. He used it to process photos. Edison in the late 1880s – early 1890s used wax paper for his “electrorock”, which was to serve for copying documents. However, the handle worked so loud that it was impossible to use, and has become one of his failed inventions.

7. Generator

The generator was in use already by the 1870s, thanks to the discovery by Michael Faraday of electromagnetic induction.
