David McCallum

In Memoriam, David McCallum, 1933-2023

David McCallum was one of the Marine Corps Scholarship Foundation’s greatest champions. His brother-in-law, Marine Corporal George Whitney Carpenter, was killed in Vietnam in 1967. Determined to keep George’s legacy alive, David and his wife, Katherine, established a scholarship through MCSF in his name to directly benefit the children of Marines. We fondly recall David weaving MCSF into the script of NCIS episodes and thrilling the audience when he served as the Master of Ceremonies for the New York Leatherneck Ball. Thank you to all those who have contributed in David’s honor. We invite everyone to watch the NCIS episode dedicated to David which will air on CBS on Monday, February 19.
