William “Doubting” Thomas, founder of the Peace Park vigil in Lafayette Park outside the White House, died last month after a long illness. The Washington Post ran its story about Thomas, born William Thomas Hallenback Jr., over the weekend. Thomas and his wife Ellen maintained their antiwar vigil for almost 28 years, and became something of a D.C. institution.

Flickr user ameschen posted this undated photo of Thomas and his dog Sophie to the DCist Flickr pool. In 2005, DCist interviewed Concepcion Picciotto, who joined William in his tent protest just a few months after it began in 1981.
