These 400 acres have been enjoyed by four generations of the Detweiler/Stackpole family.

The original home on the property was purchased by Gen. Edward J. Stackpole Jr. eight decades ago as a residence and is no longer a part of the park property. General Stackpole was president of the Telegraph Press and a co-founder with his brother Albert of Stackpole Sons, which later became Stackpole Books. “The General” (as he was fondly dubbed by his family and friends) planted all the pines behind the main house and along the trails. He also provided a home in the 1970s for the Dauphin County Anglers and Conservationists on the family property along Clarks Creek. 
In 1943, his daughter, Mary Frances “Frankie” Stackpole married Meade D. Detweiler III and they built a modest home on land adjacent to her mother and father’s home. Meade’s business interests continued the family tradition in media through WHP radio and television, Commonwealth Communications and Stackpole Books. 
Over the years, Meade and Frankie made various additions to their home and land to accommodate their family’s love of the outdoors. An avid conservationist, Meade worked diligently to improve tree health, attract wildlife, create a sustainable ecosystem and maintain walking trails on the property that the family enjoyed on a daily basis. In that same spirit, the family later donated land for the Dauphin County Conservation District’s offices. 
A 1993 letter found in Meade’s files states simply his vision for the future of this land: “The property should be an area where habitats are preserved and managed in perpetuity for wildlife based on sound ecological principles that demonstrate a strong land ethic...”
On December 30, 2016, his heirs – Susan Detweiler, wife of the late M. David Detweiler IV; Frances Detweiler Granatino; and Esme Detweiler Freedman – achieved these goals through a combination donation and sale of the property to Dauphin County.

Master Site Plan

Detweiler Park has launched its Master Site Plan process. A master site plan is a long-term planning document that serves as a blueprint for the maintenance and development of a park. It takes into consideration many things including ecosystems, buildings, social settings, surrounding environments, and economic impact.

A committee of 15 individuals have been chosen and approved by the Dauphin County Commissioners to lead this process:

  • Sally Zaino, president, Manada Conservancy
  • Julie Seeds, Middle Paxton Township manager, and park neighbor
  • Joe Sherrick, president, Dauphin County Anglers & Conservationists, which operates the E.J. Stackpole Memorial Fish Nursery in the park
  • Eric Naguski, director, Dauphin County Conservation District

  • Paula Zankel, president, Clarks Creek Watershed Preservation Association and adjoining property owner
  • Justin Goa, student, Central Dauphin High School
  • Amma Johnson, owner of Amma Jo, a local business
  • Justin Warren, vice president, Central Dauphin School District Board of Directors
  • Josh First, member, Dauphin County Planning Commission and hunting advocate
