Évariste Galois (1811–1832) was a mathematical prodigy born in France who founded a branch of abstract algebra named after him, Galois theory. He was also the first to assign the word "group" to represent a group of mathematical permutations. His mother schooled him at home until he was 12 years of age.
Of interest to many mathematics scholars is the fact that most of Galois' most important work was written done within 24 hours of his death. Of the eight pages of scribbled notes he left behind was born "group theory."
Galois' last words, as recorded by his brother Alfred, were: "Ne pleure pas, Alfred ! J'ai besoin de tout mon courage pour mourir à vingt ans!" (Don't cry, Alfred! I need all my courage to die at twenty.)
He was killed in a duel by the jealous husband of his lover when he was only 20 years old.
