Monongahela Cemetery was established over 150 years ago. The cemetery is host to veterans, historical figures and an old stone chapel.

Reporter Scott Beveridge explains this old photo: “Pennsylvania footballers. Monongahela High School. 1919. Pulled from the trash when the Daily Herald newspaper closed in 1986.”

Harold Weaver, a musician who taught scores of kids to play guitar in Monongahela, is shown, seated, second from left, in this photo taken in the 1920s. Weaver taught music lessons to more than 18,000 kids. He accomplished that by quietly walking his students through their lessons in the basement of an old apartment building in the city’s downtown, almost until the day he died in 1997.
