Jacques Charles Noel Dugé de Bernonville (December 20, 1897 – April 26, 1972) was a French collaborationist and senior police officer in the Milice of the Vichy regime in France. He was known to hunt down and execute resistance fighters during World War II, as well as for his participation in anti-semitic programs, including the deportation of French Jews to Drancy and extermination camps. After his escape from France, he was convicted of war crimes and condemned to death.
He was aided in entering Quebec, Canada in 1946 by leading Catholics of the province. In 1948 his true identity was discovered by immigration officials, who instituted deportation proceedings. De Bernonville fled to Rio de Janeiro, Brazil, where he lived the rest of his life. In 1957 the Supreme Court of Brazil refused to approve an extradition order. He was murdered by asphyxiation in 1972 by his servant's son.
Count Jacques Dugé de Bernonville was born in Paris to an aristocratic family and educated in Jesuit schools. He became aligned with conservative political groups.
In 1938, he was imprisoned for several months, charged with having taken part in the conspiracy of La Cagoule, a far right terrorist group. He was released because of lack of proof.
Following the 1940 defeat of France against Nazi Germany, Jacques de Bernonville joined the Vichy government. In 1943 he was appointed as a commander of the collaborationist Milice, the Vichy police. Working in conjunction with the head of the Milice Joseph Darnand, de Bernonville hunted down members of the French Resistance. They were almost always summarily executed.
