Alice Ferguson Foundation

Alice and Henry Ferguson acquired the Hard Bargain Farm in 1922 and became pioneers in environmental conservation. Alice was responsible for taking the first step toward protecting the area’s natural landscape and preserving the beauty of the land and the open space across from Mount Vernon. After World War II, she purchased hundreds of acres of neighboring land and sold it to conservation-minded individuals who began building homes in the area, establishing the Moyaone Reserve community. Following Alice’s death in 1951, Henry established the Alice Ferguson Foundation in 1954 as a non-profit organization. When the Potomac shoreline was threatened with industrialization in the 1960s, the Alice Ferguson Foundation donated all of its riverfront land to help establish Piscataway Park in 1968, which preserves and protects the viewshed from Mount Vernon across the river in Virginia.

Piscataway Park

Public Law 87-362 was passed and signed by President John F. Kennedy, leading to the establishment of Piscataway Park, administered by the National Park Service.

Easements were made possible through cooperation between the federal government and the Maryland state legislature by authorizing real estate tax credits and income tax deductions for donated scenic easements. The bill also authorized the National Park Service to accept donations of land from the Accokeek Foundation and the Alice Ferguson Foundation.
