Gregg Clemmer is a native of Virginia’s Shenandoah Valley and a graduate of Virginia Tech with a Master’s degree in military history from Norwich University. A former president of the Montgomery County (MD) Civil War Round Table, Gregg numbers two Union generals and 14 “in-the-trenches” Confederates in his ancestry including members of Armistead’s and the Stonewall brigades. 

Gregg has been a Smithsonian Study Leader for more than 30 years, specializing in cave as well as Civil War and Revolutionary War tours. A former professor of history at Carroll Community College in Westminster, Maryland, Gregg has also been an onboard lecturer for American Cruise Lines. He is the author of numerous magazine articles and five books including the acclaimed Valor in Gray: The Recipients of the Confederate Medal of Honor. His biography, Old Alleghany: The Life and Wars of General Ed Johnson, won the 2005 Douglas Southall Freeman History Award. 

Gregg is currently working on a sequel to his historical novel, A Turn for Home.

Yet, Gregg’s greatest passion is to bring history alive, especially when you stand on the very ground upon which it happened.

What Our Travelers Say

I very much like the educational aspect of Smithsonian Journeys...the knowledge of their Experts and their ability to relate that knowledge to us.
