Nikola tesla has a bad relationship with Edison because he used to work in Edison's company. At that time, Tesla felt that Edison didn't give him the reward and respect he deserved at work, so he resigned and concentrated on the research he wanted to do. After unremitting efforts, he finally invented the alternator.
You should know that Edison developed DC at that time, so that two people had business competition. Edison naturally didn't want his position to be threatened, so he often did some damage and even went to find some people to burn down nikola tesla's laboratory. But in the end, it is scientifically proved that alternator is more valuable than DC generator.
Of the 1 1 times that nikola tesla refused the Nobel Prize, two happened to meet Edison by accident. On those two occasions, he and Edison were awarded the same prize together. At that time, Tesla laughed and joked that he didn't want to share the prize with a liar. He had never accepted the Nobel Prize in his life. After Nicholas died, everyone called him "the man who created the twentieth century".
