Andrew Wyeth 91 — RIP

PHILADELPHIA – Renowned American artist Andrew Wyeth, famous for landscapes of his native Pennsylvania and Maine, died on Friday, according to a spokeswoman for the Brandywine River Museum near his home.

Wyeth, who was 91, died in his sleep early in the morning, surrounded by his family and friends, after a brief illness, the museum said in a statement.

He is best known for "Christina's World" (1948), in which a disabled woman appears to be striving to cross a largely empty landscape. It was painted, like many of his other works, in egg tempera, a technique that he said forced him to slow down the execution of a painting.
