Portrait of Dr. Gachet artist (a painting its owner wanted cremated with him to avoid high death taxes) (3,4)
I believe the answer is:
van gogh
(Other definitions for van gogh that I've seen before include "Sunflowers artist" , "Dutch post-impressionist painter" , "Self-mutilating artist" , "Vincent ... ...., Dutch artist who cut off his ear" , "Dutch painter, d. 1890" .)
