"Luncheon of the Boating Party" painter Pierre-Auguste (6)
I believe the answer is:
renoir
(Other definitions for renoir that I've seen before include "Pierre ---, impressionist" , "film maker" , "Jean -, Fr. film director, son of painter" , "French Impressionist painter, 1841-1919" , "Pierre Auguste ---, painter; Jean ---, film-director" .)
