William Cooper Davidon (March 18, 1927 – November 8, 2013) was an American professor of physics and mathematics, and a peace activist. As the mastermind of the March 8, 1971, FBI office break-in, in Media, Pennsylvania, Davidon was the informal leader of the Citizens' Commission to Investigate the FBI. The Media break-in resulted in the disclosure of COINTELPRO, which in turn led to subsequent investigations and reforms of the FBI.
