Louis Pierre Althusser (ˌæltʊˈsɛər, ˌɑːltuːˈsɛər; altysɛʁ; 16 October 1918 – 22 October 1990) was an Algerian-born French Marxist philosopher who studied at the École normale supérieure in Paris, where he eventually became Professor of Philosophy. Althusser was a long-time member and sometimes a strong critic of the French Communist Party (Parti communiste français, PCF). His arguments and theses were set against the threats that he saw attacking the theoretical foundations of Marxism. These included both the influence of empiricism on Marxist theory, and humanist and reformist socialist orientations which manifested as divisions in the European communist parties, as well as the problem of the cult of personality and of ideology. Althusser is commonly referred to as a structural Marxist, although his relationship to other schools of French structuralism is not a simple affiliation and he was critical of many aspects of structuralism. Althusser's life was marked by periods of intense mental illness. In 1980, he killed his wife, the sociologist Hélène Rytmann, by strangling her. He was declared unfit to stand trial due to insanity and committed to a psychiatric hospital for three years. He did little further academic work, dying in 1990. Althusser was born in French Algeria in the town of Birmendreïs, near Algiers, to a pied-noir petit-bourgeois family from Alsace, France. His father, Charles-Joseph Althusser, was a lieutenant in the French army and a bank clerk, while his mother, Lucienne Marthe Berger, a devout Roman Catholic, worked as a schoolteacher. According to his own memoirs, his Algerian childhood was prosperous; historian Martin Jay said that Althusser, along with Albert Camus and Jacques Derrida, was "a product of the French colonial culture in Northern Africa." In 1930, his family moved to the French city of Marseille as his father was to be the director of the Compagnie Algérienne (Algerian Banking Company) branch in the city. Althusser spent the rest of his childhood there, excelling in his studies at the Lycée Saint-Charles and joining a scout group.
