Belgian serial killer, described in the press as la veuve Becker (the widow Becker) or la veuve noire (the black widow), who was sentenced to death for poisoning eleven people between March 1933 and October 1936 and for having attempted to poison five others. Since the death penalty had not been applied in Belgium since 1863, the sentence was commuted to life imprisonment. Marie Becker died in prison in Brussels on 11 June 1942, aged 62.
