Édouard Depreux (October 31, 1898—October 16, 1981) was a French socialist journalist, essayist, and politician of the French Fourth Republic; he was born in Viesly (département of Nord) and died in Paris.
After serving as a member of the Sceaux commune council in 1935, and as a council member for Seine (1938-1941), he joined the French Resistance in the fight against the Nazi German military occupation, and held a high-ranking position in the SFIO executive committee, being the editor of the illegal newspaper Le Populaire. After the liberation of Paris, Depreux became mayor of Sceaux (a position he would hold until 1959), and a member of the Assemblée Consultative Provisoire that served as the legislature of France prior to the creation of the Fourth Republic; he then was elected to the French Parliament for successive terms between 1946 and 1958.
He was Minister of Education in Robert Schuman's first cabinet (Februaty-July 1948). Hostile to the European Defence Community plan proposed by René Pleven, and highly critical of the colonialism accommodated by the SFIO, Depreux nonetheless led the Party's group in the French National Assembly on two occasions.
At the same time, he became an opponent of Charles de Gaulle and Gaullism, and declared his dissatifaction with the proclamation of the Fifth Republic. Édouard Depreux left the SFIO to enter the new Autonomous Socialist Party (PSA), and then the Unified Socialist Party (PSU, created by a merger between the PSA and other groups), serving as its national secretary between 1960 and 1967.
