Bruno Bauer was a German philosopher and theologian. As a student of G. W. F. Hegel, Bauer was a radical Rationalist in philosophy, politics and Biblical criticism. Bauer investigated the sources of the New Testament and, beginning with Hegel's analysis of Christianity's Hellenic as well as Jewish roots, concluded that early Christianity owed more to ancient Greek philosophy (Stoicism) than to Judaism.

Karl Marx was a German-born philosopher, economist, political theorist, historian, sociologist, journalist, and revolutionary socialist. His best-known works are the 1848 pamphlet The Communist Manifesto and the three-volume Das Kapital (1867–1894); the latter employs his critical approach of historical materialism in an analysis of capitalism and is the culmination of his intellectual efforts. Marx's ideas and theories and their subsequent development, collectively known as Marxism, have exerted enormous influence on modern intellectual, economic and political history.
