Detweiler Park Master Plan
Detweiler Park Master Plan Appendix



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.
