Evariste Galois was a French mathematician who lived in the 18th century. He was, without a doubt, the most unfortunate of all the mathematical geniuses. His father committed himself, and he failed the Ecole Polytechnique entrance exam because he failed to provide sufficient explanations for his answers. Galois was 20 when he was killed in a battle over a young lady, six months after being sentenced to six months in prison.

Galois was 20 years ahead of his time in his thinking, and it was not until 20 years after his death that his work was fully appreciated. Despite his brief life, his pioneering work established him as the “father” of group theory, an important part of modern mathematics.
