Alfred Dreyfus ( 9 October 1859 – 12 July 1935) was a French artillery officer of Jewish ancestry from Alsace whose trial and conviction in 1894 on charges of treason became one of the most polarizing political dramas in modern French history. The incident has gone down in history as the Dreyfus affair, the reverberations from which were felt throughout Europe. It ultimately ended with Dreyfus' complete exoneration.
