Semper Fido

1925. "Sgt. Jiggs." The Marine Corps mascot in Washington, D.C., with an actual Marine. National Photo Company Collection glass negative. The USMC got the nickname "Devil Dogs" from the Germans in World War I. The term "Devil Dog" in German is a legendary boogeyman from hell in German folklore. When they saw the fierceness with which the Marines fought in France, the Germans gave the USMC this name out of fear and respect. The Corps loved it and adopted the Bulldog as their mascot. The name persists today even though it is not widely known among the general public. There are some excellent history references on this subject at the Marine Museum at the USMC Recruit Depot at Parris Island, South Carolina. Source
