Léon Blum a écrit ces Souvenirs en 1935, trente ans après "l'Affaire" et quelques mois après la mort de Dreyfus. Malgré et peut-être à cause de cette distance, ces Souvenirs, écrit Pascal Ory, "sont tout questions et tout réponses. Et pas des moindres."
André Léon Blum was the 76th and 83rd Prime Minister of France—both the first socialist and the first Jew to serve in the role—with terms on either side of World War II. After the collapse of his second ministry in 1938, he denounced the appeasement of Germany. When the Reich defeated France in 1940, he openly opposed the Vichy government, which eventually tried him on trumped-up charges resulting in his imprisonment in the Buchenwald concentration camp in April 1943. As the Allied forces advanced, he was transferred to Dachau, and then to Tyrol, from which he was rescued in May 1945. He returned to politics and by the end of the next year was Prime Minister again.
