30th May

On this day in 1832, Évariste Galois fought a duel with Perscheux d'Herbinville, the reason for the duel not being clear. He was wounded in the duel and was abandoned by d'Herbinville and his own seconds and found by a peasant. He died the following day and his funeral was held on 2 June. It was the focus for a Republican rally and riots followed which lasted for several days.

The postage stamp of one of today's mathematicians at THIS LINK was issued in 2010.
