ABOUT THE PIONEERS TEAM AND SPONSORS Charles A. Birnbaum, FASLA, National Park Service Historic Landscape Initiative and Robin Karson, executive director, Library of American Landscape History, served as project editors. Birnbaum, along with Catha Grace Rambusch, director, Catalog of Landscape Records in the United States at Wave Hill, conceived of this expansive project over a decade ago. What began as a National Park Service (NPS) database (today managed by the NPS Historic Landscape Initiative and the Cultural Landscape Foundation) gave rise to Pioneers of American Landscape Design. The National Park Service Historic Landscape Initiative (Washington, DC) promotes responsible conservation and preservation practices that protect our nation's irreplaceable legacy of historic landscapes. The Library of American Landscape History (Amherst, MA) books and exhibitions about the artistic and cultural significance of North American landscapes and the people who created them. The Catalog of Landscape Records in the United States at Wave Hill (Bronx, NY) is a database which gathers information about the location and content of document collections (both written and graphic) that tell us about the use of our land. The Cultural Landscape Foundation (Washington, DC) is the only not-for-profit foundation in America dedicated to increasing the public's awareness of the irreplaceable legacy of cultural landscapes and their importance.
