Man of principle made riches in a way (10)

Ross

I believe the answer is:

'man of principle' is the definition.
(I've seen this before)

'made riches in a way' is the wordplay.
'in a way' is an anagram indicator.
'made'+'riches'='maderiches'
'maderiches' with letters rearranged gives 'ARCHIMEDES'.

(Other definitions for archimedes that I've seen before include "Old mathematician", "'Eureka' scientist", "Greek physicist", "Greek mathematician and inventor", "Greek mathematician ('Eureka')".)

I've seen this clue in Gemini Crosswords and The Globe and Mail.
