The original Harrison School was built in 1890 as a combination grade and high school and was named for President Benjamin Harrison. It stood on the southwest corner of 7th and Maple Streets in what was then the Lebanon Independent Borough. Growth in the Borough and consolidation of all schools in the district at this location led to additions in 1905 and 1929. When the Borough became part of the city of Lebanon in 1951, Harrison became part of the Lebanon School System. A final addition built in 1960 became the nucleus of the Lebanon Senior Center. The school closed in 1976, and the older parts of the building were demolished.
