From Abel’s Heritage: Transcendental Objects in Algebraic Geometry and Their Algebrization

” Niels Henrik Abel (august 5, 1802 april 6 , 1829) ... In 1822, he entered the University of Christiania [today’s Oslo] .. died at twenty-six of tubercolosis. His best known works are: the result that algebraic equations of order five or above cannot in general be solved algebraically; the result that *Abelian equations [I.e., with Abelian Galois group] can be solved algebraically; the theory of *binomial series and of *elliptic functions; and the introduction of *Abelian functions. His work in both algebra and analysis, written in a style conducive to easy comprehension, reached the highest level of attainment of his time.”
