Tangente: Who was Niels Henrik Abel?**
François Plantade: He was a dazzling mathematician—a mathematical phenomenon. A genius who spent his life inventing new things and tackling a fairly diverse range of subjects.
Abel was born into a modest family in Norway in 1802. His father was a Lutheran pastor who educated Abel himself until his death in 1815. Niels Henrik then had four or five siblings whom he had to support financially after his father's death. He spent his entire life scrambling for money. He never managed to secure a position at the University of Kristiania (the former name of Norway's capital, Oslo), which was a real tragedy for him! Abel did not want to settle abroad: he wanted to teach at home in Norway.
Abel died in poverty from tuberculosis at the age of 26.
What was Norway like at the time?
