Edgar —, painter and sculptor whose works include 1877's Dancers Practicing at the Barre (5)
I believe the answer is:
degas
(Other definitions for degas that I've seen before include "He painted dancers" , "French artist known for his ballet scenes, d. 1917" , "Edgar -, Fr. sculptor/ painter" , "Edgar ---, Fr. impressionist" , "Edgar --, French artist" .)
