Alfred Dreyfus

Also known as: Capitaine Dreyfus

Updated on

French officer (1859–1935) wrongfully convicted in an antisemitic miscarriage of justice and cleared in 1906.

French army officer Alfred Dreyfus was wrongfully convicted of treason in 1894 amid antisemitism, secret evidence and forged documents. Convicted again in 1899, he was pardoned and finally cleared by the Court of Cassation in 1906. The old convictions are no longer valid.
