Whitakker Chambers Farm
, also known as Pipe Creek Farm
, was the home "of Whittaker Chambers
, an ex-Communist whose revelations about his past espionage activities with Alger Hiss
, a former State Department official, had major political repercussions after World War II. Here Chambers turned over the 'pumpkin papers' implicating Hiss and later wrote 'Witness,' his best-selling autobiography."
It was declared a National Historic Landmark in 1988.
The landmarking of the site is unusual, because it does not pass a usual requirement of 50 years' age for a historic event, and an advisory panel recommended against its designation. In 1988, Interior Secretary Donald P. Hodel granted national landmark status to the Pipe Creek Farm.
