Einstein or Camus (6)
I believe the answer is:
albert
I believe this clue is a double definition.
'einstein' is the first definition.
(synonyms)
'camus' is the second definition.
(I've seen this in another clue)
(Other definitions for albert that I've seen before include "chap" , "- - Finney" , "Old watch chain" , "Short kind of watch-chain" , "Prince of Monaco" .)
