Meet Évariste Galois.  Who is this dashing son of a bitch? He’s
a budding mathematician, born in 1811 in France. Smart as hell,
he greatly contributed to the branches of abstract algebra in
what are now called Galois theory and group theory. All of this
before age 20!  Galois was hard into politics. This was a period
of heavily turmoil in France, as history buffs will tell you,
and Galois was a firebrand since his early days, getting
suspended from school. When he was 18, his father committed
suicide after a heated argument with a priest. Over the years,
Galois was accused of threatening the King, protested and was
arrested, and this whole time, he kept working on his maths.  At
age 20, Galois offered to duel for a woman he had some affection
for. At some point prior to the duel, he realized this was all a
terrible idea, but unwilling to back out, he spent his last
night on earth polishing up his theorems and sending them to
friends. He was predictably shot (possibly as a result of too
little sleep?) and died
