Niels Henrik Abel and Abelian Group

Abelian Groups are named after early 19th century mathematician Niels Henrik Abel.

Abelian Groups are named after early 19th century mathematician Niels Henrik Abel. Here is how Wikipedia describes him at en.wikipedia.org/wiki/Niels_Henrik_Abel:

Niels Henrik Abel (/ˈɑːbəl/; Norwegian: [ˈɑːbl̩]; 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 350 years. He was also an innovator in the field of elliptic functions, discoverer of Abelian functions. Through the great works from Abel's hand he was known to the world's mathematicians; he made his discoveries while living in poverty and died at the age of 26 from tuberculosis.
