CHADDS FORD, Pa. — The Pennsylvania farm where Andrew Wyeth painted many of his famously bleak landscapes of faded red barns and snowy hillsides has been sold to a nonprofit organization to be preserved, possibly as a museum.

The Brandywine River Conservancy acquired the 33-acre Kuerner Farm, about 25 miles west of Philadelphia, from the Kuerner family.

The farm, which dates to the 18th century, is the site of more than 1,000 of Wyeth’s works. He painted scenes of the farm and its personalities, including Karl Kuerner, the German immigrant who moved there after World War I, and Helga Testorf, who cared for the farmer in his old age.

“It’s sort of a time capsule,” said Richard Meryman, Wyeth’s biographer. “As far as I can tell, it’s changed very little since Wyeth first went over that hill and down there to meet the man he would paint for many years.”

Karl Kuerner Jr., the farmer’s son, who is now 72 and still farms hay on the property, purchased about three-quarters of the land from his four sisters and donated it to the conservancy. The rest was purchased by the conservancy, which took title to the farm in May. The conservancy would not disclose the sale price.

The conservancy is working on a plan that could include restoring the three-story farmhouse.

Kuerner said it was the farm’s history that motivated him to preserve the property.

“The farm kind of made Andy,” he said. “And Andy kind of made the farm.”

Wyeth still lives nearby in Chadds Ford, though he spends his summers in Maine.

Wyeth first painted at Kuerner Farm in 1932 at age 15, after playing with toy soldiers there as a boy. He would draw upon the scenery time and again for more than 40 years afterward in such paintings as “Winter 1946,” “Groundhog Day” and “Evening at Kuerners.”
