Fauvist painter Henri (7)
I believe the answer is:
matisse
'fauvist painter henri' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for matisse that I've seen before include "Leading fauvist painter, d. 1954" , "French impressionist" , "French painter, Henri, d.1954" , "Henri -, Fr. artist" , "French painter, d. 1954" .)
