Michael Heinrich (born 1957, Heidelberg) is a German historian of philosophy, political scientist, and mathematician, specialising in the critical study of the development of Marx's thought. Heinrich's work, influenced by Elmar Altvater and the Neue Marx-Lektüre of Hans-Georg Backhaus and Helmut Reichelt is characterised by its focus on the points of ambivalence and inconsistency in the work of Marx. Through this theme, Heinrich challenges both the closed system he identifies with "worldview Marxism", as well as teleological narratives of Marx's intellectual development throughout his life. He is best known for his 1991 study of the theoretical field of classical political economy The Science of Value (German: Die Wissenschaft vom Wert), his introductory text to the critique of political economy An Introduction to the Three Volumes of Karl Marx's Capital, and his ongoing project to produce a multi-volume biography of Marx, of which the first volume of a projected four was published in 2020.
