Niels Henrik Abel
Niels Henrik Abel 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, had been unresolved for over 350 years. He was an innovator in the field of elliptic functions, discoverer of Abelian functions, he made his discoveries while died at the age of 26 from tuberculosis. Most of his work was done in 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: "quelle tête celle du jeune Norvégien!". The Abel Prize in mathematics proposed in 1899 to complement the Nobel Prizes, is named in his honour. Niels Henrik Abel was born 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 / 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 Finnøy. Søren's father, Niels's grandfather, Hans Mathias Abel, was a pastor, at Gjerstad Church near the town of Risør. Søren had spent his childhood at Gjerstad, had served as chaplain there; the Abel family came to Norway in the 17th century. Anne Marie Simonsen was from Risør. Anne Marie had grown up with two stepmothers, in luxurious surroundings. At Gjerstad rectory, she enjoyed arranging social gatherings. Much suggests she was early on an alcoholic and took little interest in the upbringing of the children. Niels Henrik and his brothers were given their schooling by their father, with handwritten books to read. An addition table in a book of mathematics reads: 1+0=0.
With Norwegian independence and the first election held in Norway, in 1814, Søren Abel was elected as a representative to the Storting. Meetings of the Storting were held until 1866 in the main hall of the Cathedral School in Christiania; this is how he came into contact with the school, he decided that his eldest son, Hans Mathias, should start there the following year. However, when the time for his departure approached, Hans was so saddened and depressed over having to leave home that his father did not dare send him away, he decided to send Niels instead. In 1815, Niels Abel entered the Cathedral School at the age of 13, his elder brother Hans joined him there a year later. They had classes together. Hans got better grades than Niels, he gave the students mathematical tasks to do at home. He saw Niels Henrik's talent in mathematics, encouraged him to study the subject to an advanced level, he gave Niels private lessons after school. In 1818, Søren Abel had a public theological argument with the theologian Stener Johannes Stenersen regarding his catechism from 1806.
The argument was well covered in the press. Søren was given the nickname "Abel Treating". Niels' reaction to the quarrel was said to have been "excessive gaiety". At the same time, Søren almost faced impeachment after insulting Carsten Anker, the host of the Norwegian Constituent Assembly, he began drinking and died only two years in 1820, aged 48. Bernt Michael Holmboe supported Niels Henrik Abel with a scholarship to remain at the school and raised money from his friends to enable him to study at the Royal Frederick University; when Abel entered the university in 1821, he was the most knowledgeable mathematician in Norway. Holmboe had nothing more he could teach him and Abel had studied all the latest mathematical literature in the university library. During that time, Abel started working on the quintic equation in radicals. Mathematicians had been looking for a solution to this problem for over 250 years. In 1821, Abel thought; the two professors of mathematics in Christiania, Søren Rasmussen and Christopher Hansteen, found no errors in Abel's formulas, sent the work on to the leading mathematician in the Nordic countries, Carl Ferdinand Degen in Copenhagen.
He too found no faults but still doubted that the solution, which so many outstanding mathematicians had sought for so long, could have been found by an unknown student in far-off Christiania. Degen noted, Abel's unusually sharp mind, believed that such a talented young man should not waste his abilities on such a "sterile object" as the fifth degree equation, but rather on elliptic functions and transcendence. Degen asked Abel to give a numerical example of his method. While trying to provide an example, Abel found a mistake in his paper; this led to a discovery in 1823 that a solution to a fifth- or higher-degree equation was impossible. Abel graduated in 1822, his performance was exceptionally high in average in other matters. A
