Evariste Galois was a brilliant mathematician whose genius was not well recognized. His examiners had difficulty understanding his explanations, and he often proclaimed most of them were so easy as not to require an explanation. He wrote very little in his career and accurately predicted he would die in a duel. He was known for working in group theory, Galois theory, and algebra.
