 Like “rationalism” and “empiricism,” “existentialism” is a term that belongs to intellectual history. Its definition is thus to some extent one of historical convenience. The term was explicitly adopted as a self-description by Jean-Paul Sartre, and through the wide dissemination of the postwar literary and philosophical output of Sartre and his associates—notably Simone de Beauvoir, Maurice Merleau-Ponty, and Albert Camus—existentialism became identified with a cultural movement that flourished in Europe in the 1940s and 1950s. Among the major philosophers identified as existentialists (many of whom—for instance Camus and Heidegger—repudiated the label) were Karl Jaspers, Martin Heidegger, and Martin Buber in Germany, Jean Wahl and Gabriel Marcel in France, the Spaniards José Ortega y Gasset and Miguel de Unamuno, and the Russians Nikolai Berdyaev and Lev Shestov. The nineteenth century philosophers, Søren Kierkegaard and Friedrich Nietzsche, came to be seen as precursors of the movement. Existentialism was as much a literary phenomenon as a philosophical one. Sartre’s own ideas were and are better known through his fictional works (such as Nausea and No Exit) than through his more purely philosophical ones (such as Being and Nothingness and Critique of Dialectical Reason), and the postwar years found a very diverse coterie of writers and artists linked under the term: retrospectively, Dostoevsky, Ibsen, and Kafka were conscripted; in Paris there were Jean Genet, André Gide, André Malraux, and the expatriate Samuel Beckett; the Norwegian Knut Hamsun and the Romanian Eugene Ionesco belong to the club; artists such as Alberto Giacometti and even Abstract Expressionists such as Jackson Pollock, Arshile Gorky, and Willem de Kooning, and filmmakers such as Jean-Luc Godard and Ingmar Bergman were understood in existential terms. By the mid 1970s the cultural image of existentialism had become a cliché, parodized in countless books and films by Woody  Allen.[1]
