Frederick Tilberg

Frederick Tilberg was an American writer and historian best remembered for Gettysburg National Military Park, a handbook published by the U.S. Department of the Interior as part of the National Park Service Historical Handbook series. Surviving catalog and bookseller records connect him closely with Gettysburg and with public-facing historical writing.

He also appears in Library of Congress material as a photographer for the Historic American Buildings Survey in the 1950s, suggesting a broader involvement in documenting historic sites and landscapes. That fits the practical, educational character of the work associated with his name.

Reliable biographical details about his personal life are limited in the sources I could confirm here, so it is safest to remember him mainly through his contributions to American public history and historic preservation.
