Washington & Jefferson College, also known as W & J College or W&J, is a private liberal arts college in Washington, Pennsylvania, in the United States, which is 30 mi (48 km) south of Pittsburgh. The college traces its origin to three log cabin colleges in Washington County established by three Presbyterian missionaries to the American frontier in the 1780s: John McMillan, Thaddeus Dod, and Joseph Smith. These early schools eventually grew into two competing academies and colleges, with Canonsburg Academy, later Jefferson College, located in Canonsburg and Washington Academy, later Washington College, in Washington. These two colleges merged in 1865 to form Washington & Jefferson College. The 60-acre (24 ha) campus, located in Washington, Pennsylvania, has more than 40 buildings, with the oldest dating to 1793. While the college has historically had a difficult relationship with the city of Washington, including clashes over college expansion and finances, recent efforts have been made to improve those relations.
