State Historic Preservation Office Employee, African American History Expert Makes National Trust 40-Under-40 List

DOVER, Del. – Carlton Hall, a cultural preservation specialist and historian with the Delaware State Historic Preservation Office (SHPO), earned a place on the inaugural “40 Under 40” list recently unveiled by the National Trust for Historic Preservation.

Hall was honored for his research and presentations about Delaware listings in the Green Book, a segregation-era travel guide for African Americans created by Victor Green and published annually from 1936 through 1966. The Green Book listed hotels, restaurants, service stations, night clubs, barber shops and other establishments across the country where African Americans would be safely welcomed during the days of Jim Crow.

“This honor means a great deal to me as a practitioner in my field, and I’m privileged to represent our state as the only individual from Delaware on the list,” Hall said. “I’ve learned and continue to learn from an outstanding group of professionals in the SHPO office, and to benefit from their decades of experience in the field of historic preservation.”

Hall is a native of New Castle, a graduate of William Penn High School and now lives in Bear with his wife and three children. He earned a master’s degree in historic preservation from Delaware State University in 2013 and began his tenure at SHPO in 2015.

“We couldn’t be prouder of Carlton and the recognition he has received,” said Tim Slavin, state historic preservation officer and director of the Division of Historical and Cultural Affairs. “Carlton has a long career ahead of him, and we know he will continue to distinguish himself as he works to preserve our state’s history for future generations.”

“40 Under 40: People Saving Places” is a new initiative of the non-profit National Trust for Historic Preservation, honoring individuals under the age of 40 across the United States who are working to support the mission of historic preservation through fields such as architecture, community activism and business.
