The History Center is committed to collecting, preserving, and providing access to materials that document the stories of Western Pennsylvanians over the past 250 years.

Our materials range from the extraordinary — the original set from the iconic television show “Mister Rogers’ Neighborhood” — to the quirky — a piece of hair that may or may not be from the head of George Washington — to the everyday — photographs of family gatherings and yearbooks from yesteryear.

In addition to general collections, the History Center also has special initiatives for the collection of ethnic artifacts, including the African American Program, the Italian American Program, and the Rauh Jewish Archives.
