Georges Politzer (French: [pɔlidzɛʁ]; 3 May 1903 – 23 May 1942) was a French philosopher and Marxist theoretician of Hungarian origin, affectionately referred to by some as the "red-headed philosopher" (philosophe roux). He was a native of Oradea, a city in present-day Romania (then Nagyvárad, Hungary).
Politzer was already a militant by the time of his involvement in the Hungarian insurrection of 1919. At age seventeen, the Hungarian Soviet Republic led by Béla Kun was overthrown and he went into exile during the so-called White Terror that preceded the establishment of a right-wing government under the regency of Admiral Miklós Horthy.
He settled in Paris in 1921 after meeting Freud and Sándor Ferenczi in Vienna. He joined the French Communist Party somewhere between 1929 and 1931.
At the beginning of the 1930s, the Communist Party founded the Workers University of Paris (l'Université Ouvrière de Paris) which lasted until dissolution by German occupation in 1939. During his tenure at the university, Politzer was entrusted with and given charge of a course on dialectical materialism.
A disciple of Marx and Lenin, Politzer was very interested in psychology, preaching the concrete aspects of this field, in relation to which he qualified traditional psychology as abstract. He also took a lively interest in Freudian theory and its uses before eventually distancing himself from it. In this same period, he occupied the post of professor of philosophy at Lycée Marcelin Berthelot in Saint-Maur-des-Fossés.
