Author of Das Kapital (4)

I believe the answer is:

marx

'author of das kapital' is the definition.
(I've seen this before)

This is the entire clue.

(Other definitions for marx that I've seen before include "The Economist" , "Communist or funny brother?" , "Karl, top communist" , "Groucho's surname" , "Second part of 20" .)

I've seen this clue in The Guardian and The Times.
