  Edison's childhood is partly reminiscent of the childhood of another ingenious inventor - Konstantin Tsiolkovsky. Both suffered a scarlet fever and were almost deaf, both were found unfit for school. But if Tsiolkovsky studied at school for several years, then Edison went to school only three months, after which he was called a teacher "brainless." As a result, Edison received only a home education from his mother.

  His first patent Edison registered at 22 years. Today we recall the most important technical achievements of an American engineer, which have influenced the modern world to the maximum.

  Electric counter votes in elections
  1
  This was Edison's first patent. The device allowed voters to press the "yes" or "no" button, instead of writing on paper. Unfortunately, there was no demand for this device - as it turned out, when using it, politicians could no longer shamelessly deceive those present and, with the help of fraudulent results, incline their colleagues to change their minds. Parliament declined the invention in favor of the usual written account.

  Automatic Telegraph
  2
  To improve the telegraph, Edison created one more - on the basis of the perforated boron he invented - for which he did not need a man to print a message on the other end. This new technology has increased the number of words transmitted per minute from 25-40 to 1000! Edison also became the inventor of the "talking telegraph".

  Stencil-Pen
  The forerunner of the perforated boron, which made holes in the telegraphs, was an electrobrush that created a stencil for the writer, which could be used to squeeze ink on paper and make duplicates.

  Phonograph
  Phonograph recorded and played audible sounds first with paraffin paper, and then using metal foil on the cylinder. Edison has created many versions in a few years, more and more improving each of the models.

  Coal Phone
  Edison improved the weak point of Alexander Bell's phone - a microphone. The original version used a carbon rod, but Edison decided to use a carbon battery, which markedly increased the stability and range of the signal.

  Incandescent lamp with carbon filament
  The Edison incandescent lamp with carbon filament was the first commercially profitable source of electric lighting. Previous versions were not so powerful and too expensive materials, such as platinum, were used for their manufacture.

  Electric generator
  Edison designed a device to control the supply of electricity between devices - this idea was used in many of his creations, such as an incandescent lamp.

  (loudspeaker phone)
  This device lowered the electrical currents from high to low, which allowed the transmission of voice sounds to long distances and at a higher volume. Another invention of Edison - coal rheostat - helped create a motor. The Edison's loudspeaker phone was used for several years in England.

  Kinetoscope
  Edison was looking for a way to create "a tool that would make for the eye the same thing as a phonograph for the ear." The kinetoscope showed the photos in quick succession, because of what it seemed as if the image was moving.

  Alkaline battery
  Experimenting with the nickel-iron battery, Edison used an alkaline solution, which made it possible to get a more "long-playing" battery. This product later became one of the best-selling.
