Who is so unlucky, because Newton was offended, his only portrait was destroyed after his death and was labeled as a madman?

Because robert hooke offended Newton, the only portrait after his death was destroyed and was branded as a madman. Newton is a controversial person in history. Most people only know him as the "father of physics". He discovered the law of gravity, founded calculus, and made amazing achievements in physics and mathematics, but few people knew his other side. Hook actually contributed to Newton's discovery of gravity, and they had a competitive relationship in the discovery of gravity.

Although Newton once said that his achievements were made on the shoulders of his predecessors, some people lost their due reputation and achievements because of him. As the president of the Royal Society, Newton suppressed Leibniz, who founded calculus independently. Instead, Leibniz was regarded as his own plagiarist, and the use of Leibniz's calculus symbols was forbidden, which led to the fact that Britain in the18th century was far behind Europe in the development of mathematics. He also suppressed, obstructed and copied the research results of Fransted and others.

Hooke was actually a great scientist who made great contributions in many fields, and was even called "Da Vinci of Britain" by later scholars of history of science. But because Newton was offended, he was forgotten by the world. It was not until the 20th century that his important position in the scientific community was confirmed. In addition to Hooke's law of elasticity, which we learned in junior high school, Hooke also made a compound microscope to discover the existence of cells, invented a variety of scientific measuring instruments, and enjoyed a high reputation in architectural design.

Newton and Hooke have always been tit-for-tat in the academic field, with constant conflicts. Hooke has repeatedly refuted Newton's academic arguments in public. Although young Newton endured everywhere, he still had resentment in his heart. The contradiction between them is because the priority discoverer of the law of universal gravitation has reached a climax. Hook was very dissatisfied with the successful Newton. He was jealous that Newton took the success of the law of gravity as his own, but his help to Newton was little known, and finally he died of depression.
