Edison Thomas Alva

Edison Thomas Alva is an American inventor, on the account of which - 1098 patents. That's why Edison became one of the most famous inventors. At the age of 12, Tom dropped out of school and went to work as a newsboy. Then he mastered the profession of a telegraph operator - he brilliantly studied the technique of the work of telegraphy and the telegraph apparatus itself.

The first invention Edison Thomas Alva did with the telegraph apparatus, and he did it for his own pleasure: he designed a prefix that automatically and periodically sent a conditional signal to the station, confirming that the telegraph operator was vigilantly on duty with the apparatus. And he himself was asleep at that time. The second invention of T. Edison concerned also telegraph and turned out to be very necessary for dealers-stockbrokers. He adapted the telegraph unit to send information about exchange rates of currency and shares for a distance, and earned his first $40000 on this, after which he devoted himself entirely to inventive activity.

This was in 1869. Since then, for 61 years, Edison Thomas Alva has been busy with inventive work and work on the introduction of its innovations in production. He set a schedule for himself, which worked at least 19,5 hours a day, and only in the declining years reduced the load. Edison showed great persistence on the way to achieving the goal. Having set himself the task of creating a plant for the production of carbolic acid, he did not leave the laboratory for 168 hours, slept only snatches on the table, but solved the problem. In order to create an alkaline battery, he spent about 50 thousand experiments. In 1878, Thomas Alva Edison turned to the problem of electric lighting, followed the path of improving the incandescent lamp of AN Lodygin. For one year he spent 6 thousand experiments in search of the best material for filament lamp filament. Lamps Edison received recognition, but still, the best material for the filament - tungsten suggested a few years later, A.N. Lodygin.

The telegraph was known before Edison. But it was Edison Thomas Alva who found a way to send two or four telegrams on the same cable one at a time. The phone was invented by A. Bell, but Edison made significant improvements to it, which eliminated extraneous noise and allowed to hear the interlocutor well at any distance. He developed a method for recording telegrams on the surface of a flat rotating disk. The needle spiraled on the disk points and dashes. One more step forward and - there is an apparatus, but already recording not a telegraph code, but the sounds of human speech - a phonograph. And just as Edison Thomas Alva previously developed the ideas of his predecessors, now the inventors of different countries went along the open path: a graphophone was created, then a gramophone, a gramophone, a record player. Edison sent one of his first phonographs to L. Tolstoy, and thanks to this, the voice of the great Russian writer was preserved for posterity.

In the declining years Edison Thomas Alva thought about finding a successor. Only two of the 40 candidates passed the most difficult exam. Of these, good engineers subsequently turned out.
