I writing a book on the trial of Klaus Barbie in France in 1987. Known as the “Butcher of Lyon,” Barbie was responsible for atrocities ranging from the torture of resistors to the deportation of Jewish children to Auschwitz-Birkenau. Following the war the United States Counter-Intelligence Corps hired him to help uncover communist cells in Germany, and then helped him to escape to Bolivia in 1951 after repeated French requests for extradition. He was uncovered 1971, returned to France in 1983, and tried four years later. France’s most famous Holocaust trial revealed the fissures in memory between the French resistance, Holocaust victims, and France’s colonial past.
