TIMELINE OF PRESERVATION ACTION THROUGH THE DECADES

1970s

  • Founded 1974 by DC-based attorney Tersh Boasberg and Beverly Blount Hemphill (San Antonio Conservation Society – San Antonio, TX), who later formed a small coalition with Arthur Ziegler (President of Pittsburgh History and Landmarks Foundation- Pittsburgh, PA), J. Reid Williamson (Executive Director of Historic Landmarks Foundation of Indiana- Indianapolis, IN), Leopold Adler, II (Historic Savannah-Savannah, GA), St. Clair Wright, President of Historic Annapolis- Annapolis, MD) to promote preservation at the federal level. 
  • PA appointed its first official president Nellie Longsworth in 1975. Under her leadership, PA helped pass the 1976 Federal Historic Tax law incentive; a credit which saved many historic buildings throughout the country.
  • 1977 the Historic Preservation Fund (HPF) is established to support the vision and framework of the National Historic Preservation Act.

  • PA establishes the 2017 Nellie Longsworth Award for Outstanding Leadership.

2020s

  • 2021 Nellie Longsworth passed away at the age of 87. PA establishes the Nellie Longsworth Memorial Fund.
  • Long-time PA supporter and employee Bruce MacDougal passes away in 2022, and the PAF Advocacy Scholars program is renamed in his honor.
