Until 2015, near the eastern border with Chalfant, there once stood an historic, five-million-volt Van de Graaff generator and particle accelerator known as the Westinghouse Atom Smasher. The Atom Smasher operated from 1937 to 1958, and because of many important discoveries that were made using the device—it was designated an official historic landmark in 2010. However, the apparatus was torn down in 2015, when the property that had served as the primary campus of the Westinghouse Research Laboratories from 1916 to 1956 was being prepared for redevelopment.
