He wrote in the Bastille (8)

I believe the answer is:

voltaire

(Other definitions for voltaire that I've seen before include "Candide satirist" , "French author of Candide, d. 1778" , "French writer (Candide)" , "polemical writer" , "French writer/philosopher" .)

I've seen this clue in the Newsday.
