Niels Henrik Abel (1August 5, 802-1April 6, 829), a Norwegian mathematician, has done pioneering work in many fields of mathematics. One of his most famous achievements is the first complete proof that there is no general algebraic solution for general algebraic equations higher than quartic. This problem was one of his most famous unsolved problems at that time, and it was a suspense for more than 250 years. He is also a pioneer in the field of elliptic functions and the discoverer of Abelian functions. Although Abel achieved great success, he was not recognized before his death and lived in poverty.

1in the winter of 828, Abel's condition became more and more serious. During Christmas, he went to Frohland to visit his fiancee, Kemp, and his condition deteriorated. By 1829, 1 month, he knew that his days were numbered and the symptoms of bleeding could not be denied. Until1April 6, 829, Abel died, and his fiancee insisted on taking care of Abel without other people's help, "bearing this last moment alone."
