Karl Marx (1818–1883), German political theorist, social philosopher. "Notebook 2," Grundrisse (written 1857-1858, publ. 1939).
The Grundrisse or outline, is a rough draft of Marx's master work, Das Capital. It was unknown until its publication in 1939, when it caused great controversy amongst academics, revealing as it does (along with other previously lost works) an apparently more philosophical and humanist Marx.
