/kloc-at the beginning of the 0/9th century, people began to use gas lamps, but gas was supplied by pipelines. Once it is leaked or blocked, it is very prone to accidents, and people are very eager for the reform of lighting. In fact, Edison set himself an impossible task: in addition to improving lighting, he must also create a power supply system.

So he and his partners in Romon Garden worked tirelessly on heat-resistant materials and more than 600 kinds of plant fibers for more than 65,438+0,600 times before making the first carbon filament light bulb, which can burn for 45 hours at a time. Later, he constantly improved the manufacturing method on this basis, and finally introduced a bamboo filament light bulb that can ignite 1200 hours.

Telegraph profession

1862 One day in August, Edison saved a boy on the train track. The boy's father was Mackenzie, the stationmaster of this railway station. He was very grateful for this and taught Edison the telegraph technology. Under the guidance of Mackenzie, Edison learned the telegraph technology and sent his first telegram.

1863, Edison was introduced by Mackenzie as a telecom operator in Stratford Hub Station, but he was soon dismissed. ?

During the period from 1864 to 1867, Edison worked as a telegraph operator in the United States and lived an insecure vagrant life. During this period, Edison changed ten workplaces, was fired five times, and resigned five times by himself, and traveled all over Stratford, Adrian, fort wayne, Indianapolis, Cincinnati, Nashville, Tennessee and Memphis.
