Léon Blum was a French socialist leader and politician, who served as Prime Minister of France thrice in his career. While serving as the head of the ‘Popular Front’ government, he introduced innovative reforms to improve the economic and social sectors of France. Born into a wealthy Alsatian Jewish family, he completed his primary education from elite schools and went on to earn a degree in law and literature from the prestigious University of Paris. He began his career as a lawyer and pursued his interest as a literary critic. However, the ‘Dreyfus affair’ that occurred in the late 1890s affected him deeply and influenced him to associate himself with socialism. As Prime Minister, he brought about changes like wage increase for labourers by 7-15%, standard 40 working hours per week, paid vacation of twelve days, granting the right to strike and bargain and so on. With the German invasion of France during the World War II he was arrested and imprisoned, only to be rescued by Allied troops later. In his final years, he served as French Ambassador to the U.S and the head of the French mission of UNESCO.
