A darker, more modern version of Van Gogh
Lucian Micahel Freud (1922–2011) was, yes, the grandson of the famous psychiatrist.
Lucian was actually born in Berlin, the son of Jewish architect, but his family moved to London in 1933 to escape the Nazis (the rest of the Freud clan, including Grandpa Sigmund, followed in 1938).
Lucian Freud's incisive portraits and marvelous nudes live in an (often vaguely depressing) version of Van Gogh's world, all done in thick paint, fluid lines, and harsh lighting.
