Andrew Wyeth
(1917 - 2009)
 

Andrew Newell Wyeth was an American visual artist, primarily a realist painter, working predominantly in a regionalist style. He believed he was also an abstractionist, portraying subjects in a new, meaningful way. The son of N. C. Wyeth and father of Jamie Wyeth, he was one of the best-known U.S. artists of the middle 20th century.

Victoria [Wyeth's granddaughter] said the artist had come home tired one evening, wanting to take a nap, only to find Rattler had got there first. Andy's comment was, "You know, dogs are the damnedest thing. They just take over the house." Hence the title of the painting, "Master Bedroom." No mistaking who's in charge.
