Elizabeth S. Hartwell

The Elizabeth Hartwell Mason Neck National Wildlife Refuge is named in her memory.

Beginning in 1965, while living in Mason Neck, Hartwell campaigned against several large-scale development and other intrusive land use plans,[4] working to preserve the natural environment of the peninsula, to protect bird habitats and ultimately to establish the Mason Neck National Wildlife Refuge, Mason Neck State Park, and Pohick Bay Regional Park.

She attended zoning board meetings, gave speeches, conducted boat tours, organized phone and mail campaigns, and made a film to promote her cause.

[7] Elizabeth Speer married engineer and businessman Stephen Hartwell in 1946, and lived in Mason Neck, Virginia.

[3][8] Mason Neck National Wildlife Refuge was renamed for Hartwell by an act of Congress in 2006.
