The small borough is named after the first American president, George Washington. Before the time of the town's founding during the Revolutionary War, Fort Bosley stood along the eastern backs of Chillisquaque Creek near its confluence with Mud Creek. During, the early 20th century, millionaire Frank DeLong would often visit the borough to get away from the city. He ended up donating a school, which at the time was considered one of the best facilities in the country, to the town. He also turned the old Presbyterian Church into a memorial for his mother. Today, the old school building is now a nursing home, and the memorial still stands today, containing many historical artifacts. Recently, the remains of an 18th century log cabin were discovered at the corner of Front and Water Streets, suggesting early settlement of permanent residents.
