Niels Henrik Abel
Norwegian mathematician (1802–1829)
Niels Henrik Abel ( AH-bəl, Norwegian: [ˌnɪls ˈhɛ̀nːɾɪk ˈɑ̀ːbl̩]; 5 August 1802 – 6 April 1829) was a Norwegian mathematician who made pioneering contributions in a variety of fields. His most famous single result is the first complete proof demonstrating the impossibility of solving the general quintic equation in radicals. This question was one of the outstanding open problems of his day, and had been unresolved for over 250 years. He was also an innovator in the field of elliptic functions and the discoverer of Abelian functions. He made his discoveries while living in poverty and died at the age of 26 from tuberculosis.
Most of his work was done in six or seven years of his working life. Regarding Abel, the French mathematician Charles Hermite said: "Abel has left mathematicians enough to keep them busy for five hundred years." Another French mathematician, Adrien-Marie Legendre, said: "What a head the young Norwegian has!"
Life
Early life
Niels Henrik Abel was born prematurely in Nedstrand, Norway, as the second child of the pastor Søren Georg Abel and Anne Marie Simonsen. When Niels Henrik Abel was born, the family was living at a rectory on Finnøy. Much suggests that Niels Henrik was born in the neighboring parish, as his parents were guests of the bailiff in Nedstrand in July and August of his year of birth.
Niels Henrik Abel's father, Søren Georg Abel, had a degree in theology and philosophy and served as pastor at Hesby Church on Finnøy.

Why this record matters
“Niels Henrik Abel” is worth following because a concise public description often conceals a longer documentary argument. Here, Niels, Henrik and Abel provides the most credible route into that argument.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q124115. VIAF identifies the subject as 66522208. The Library of Congress control number is n84804842. 4 of 4 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1802 and 1829.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
