Wilhelm Dilthey
Mannheim's life, one of intellectual and geographical migration, falls into three main phases: Hungarian (to 1919), German (1919–1933), British (1933–1947). Among his valued interlocutors were György Lukács, Oszkár Jászi, Georg Simmel, Martin Heidegger, Edmund Husserl, Karl Marx, Alfred and Max Weber, Max Scheler, and Wilhelm Dilthey. In his work, he sought variously to synthesize elements derived from German historicism, Marxism, phenomenology, sociology, and Anglo-American pragmatism.
