Washington & Jefferson College is a private liberal arts college in Washington, Pennsylvania, which is located in the Pittsburgh metropolitan area. The college traces its origin to three log cabin colleges in Washington County, Pennsylvania established by three frontier clergymen in the 1780s: John McMillan, Thaddeus Dod, and Joseph Smith. These early schools eventually grew into two competing colleges, with Jefferson College in Canonsburg, Pennsylvania being chartered in 1802 and Washington College being chartered in 1806. These two schools merged in 1865 to form Washington & Jefferson College. As of 2009, Washington & Jefferson College had about 12,000 living alumni. Before the union of the two colleges, Washington College graduated 872 men and Jefferson College graduated 1,936 men. The alumni association recognizes as alumni all students who have completed at least one college year as full-time students. These alumni include James G. Blaine, who served in Congress as Speaker of the House, U.S. Senator from Maine, two-time United States Secretary of State and the Republican nominee for the 1884 presidential election. Other graduates have held high federal positions, including United States Secretary of the Treasury Benjamin Bristow and United States Attorney General Henry Stanbery, who successfully defended Andrew Johnson during his impeachment trial. As a U.S. Congressman, Clarence Long was a key figure in directing funds to Operation Cyclone, the CIA's effort to arm the mujahideen in the Soviet-Afghan War.
