Klaus Barbie, byname Butcher of Lyon (born Oct. 25, 1913, Bad Godesberg, Ger.—died Sept. 25, 1991, Lyon, France), Nazi leader, head of the Gestapo in Lyon from 1942 to 1944, who was held responsible for the death of some 4,000 persons and the deportation of some 7,500 others.
Barbie was a member of the Hitler Youth and in 1935 joined the Sicherheitsdienst (SD; “Security Service”), a special branch of the SS. After German forces overran western Europe in World War II, Barbie served in the Netherlands and then, in 1942, was made chief of Gestapo Department IV in Lyon. (The SD was closely related to the Gestapo, and personnel were frequently transferred from one to the other.) In this position he became especially active against French partisans, promoting the torture and execution of thousands of prisoners. He personally tortured prisoners whom he interrogated. Among the more specific charges against him were that he ordered the death of French Resistance leader Jean Moulin and the deportation of 44 Jewish children (aged 3–13) and their five teachers, all of whom later were delivered to the Auschwitz extermination camp.
After the war Barbie was seized by American authorities, who recruited him (1947–51) for counterintelligence work and then spirited him and his family out of Germany to Bolivia (actions for which the U.S. government later officially apologized to France). Beginning in 1951, he lived as a businessman under the name Klaus Altmann in Bolivia, where Nazi hunter Beate Klarsfeld tracked him down in 1972. After long negotiations, the Bolivian government extradited him to France in February 1983 to stand trial. (He had twice been sentenced in absentia to death by a postwar French military tribunal.) In 1987 Barbie, who remained unrepentant and proud of his wartime service, went on trial in Lyon and was convicted of “crimes against humanity,” for which he was sentenced to life imprisonment. Four years later, he died in prison.
