Who is known as the "Grand Old Man of the Marine Corps"?

The title "Grand Old Man of the Marine Corps" refers to Archibald Henderson, who served as the 5th Commandant of the United States Marine Corps from 1820 to 1859. His leadership spanned nearly four decades, during which he significantly influenced the Corps' organization, doctrine, and esprit de corps. Henderson is credited with modernizing the Marine Corps and advocating for an independent Marine force, solidifying its identity and role within the U.S. military. His tenure is marked by a commitment to high standards and professionalism, helping to establish the legacy and traditions that the Marine Corps upholds today.

In contrast, Lewis B. Puller, while a distinguished Marine Corps officer and a notable figure in its history, is not referred to by that specific title. Colonel John W. Thomason was known for his contributions as a Marine artist and author but does not hold the honorary title associated with Henderson. General David H. Berger, as the current Commandant, is shaping the future of the Corps but does not yet have the historical legacy associated with the title of "Grand Old Man."
