If you list scientists with bad reputations, many people may be shocked. For example, Edison, Newton, Einstein, these great scientists, in fact, their personal morality is very poor.
First, let's talk about Edison. He knows more about some evil deeds than the other two. He has done a lot of things to persecute other scientists, for example, using means to occupy other scientists' invention patents, and throwing dirty water on other scientists for his own benefit.
Then Newton. Newton is a very positive image in many people's minds, but he is not a noble man. One of his laws was rejected by Hooke, and later Newton himself used Hooke's theory, but he felt that Hooke hit him in the face and used Hooke's theory without quoting it. Use their power to suppress scientists who do the same research with themselves, and even accuse this scientist of stealing his research results.
The third is Einstein, whose reputation is that he is too mean to his wife. Einstein cheated his wife in many marriages. Once he had no feelings for his wife, he would treat them badly and completely forget his old feelings with his wife.
