At that time, Edison was a particularly prestigious science, and some young people with new talents naturally came here to invest in Edison's company, hoping that they could be reused and give full play to their talents. It's just that they didn't expect their invention to eventually become Edison's invention.
Tesla should be the worst one who was pitted by Edison. Tesla is a well-deserved genius. The electricity we use now is alternating current invented by him. Edison discovered Tesla's talent after joining his company, and asked Tesla to help him with some research and inventions, and gave him some benefits afterwards. But when Tesla completed the task, not only did he not get any benefits, but he even found that his invention was applied by Edison as a patent named Edison. These patents include the design of 2 1 DC generators, all completed by Tesla. Tesla certainly won't eat this dumb loss, but when he looked for Edison's theory, he was told that Tesla belongs to the company's employees, so the invention certainly belongs to the company.
Edison was shameless enough to steal the patents of company employees, and it was only natural that he didn't pay for his invention. Such people are sometimes called patent protectors, which is the most ironic. Edison was an out-and-out capitalist egoist.
