The Skyscraper Museum would like to thank the many individuals, firms, and institutions who aided our
research, answered queries, and helped with models, drawings, and photography in the exhibition.

First and foremost, we thank the Landmarks Preservation Commission and the LPC agency and staff for their work through the decades. In recent years, the LPC digital mapping team has created online public resources that were invaluable to our research and visualization of the geography of skyscraper Landmarks.

We also acknowledge the unbelievably useful collective effort of Wikipedia editors and contributors in publishing a list of all Manhattan Individual Landmarks organized by area (in logical divisions we adopted), that can also be reordered by designation date. We used this tool to filter the buildings that we considered “skyscrapers.”

We are grateful to the New York Preservation Archive Project (NYPAP) for their oral histories with past Chairs of the LPC, and we urge them to complete their list of interviewees. Among devoted preservationists, we thank our friend Andrew S. Dolkart for his work on the early history of the slow designation of skyscrapers. For a lecture he gave at the Museum in 2015, he documented the impact of the Marcel Breuer design for a destructive slab tower above Grand Central Terminal that precipitated both the litigation against and the validation of the Landmark Law. A long excerpt of his talk is included in the exhibition.
