It is very sad that some of the most brilliant mathematicians had died early in their life. Had these men lived their full lives, they would have made tremendous advancement in the field of mathematics. Get to know the 10 mathematicians who died at the age of 40 and below.

##### 1. Evariste Galois (25 October 1811 – 31 May 1832; aged 20)

Evariste Galois was a French mathematician. He was probably the most unfortunate among all the mathematicians. His father committed suicide; he failed the entrance exam at *Ecole Polytechnique* for failure to explain his answers. He was jailed for six months and was killed in a duel over a young lady at the age of 20 (see his 10 misfortunes).

Galois was ahead of his time. His work was not understood until 20 years after his death. Despite his short life, his groundbreaking work made him the ‘father’ of group theory, an important branch of modern mathematics. » Read more
