Andrew Wyeth, one of the USA's most acclaimed artists, died this morning at the age of 91... "Andy Wyeth died in his sleep peacefully at 4:25 today," Phyllis Wyeth, his daughter-in-law, tells the paper.

In 2007, President Bush presented a National Medal of the Arts to Wyeth in recognition of "a lifetime of paintings whose meticulous realism have captured the American consciousness, and whose austere vision has displayed the depth and dignity of American life."
