So in regards to Rhino Tanks during WWII. Wikipedia writes:
"The invention of a hedge-breaching device is generally credited to Curtis G. Culin, a sergeant in the 2nd Armored Division's 102nd Cavalry Reconnaissance Squadron. However, military historian Max Hastings notes that Culin was inspired by "a Tennessee hillbilly named Roberts"
My Grandfater is the one who invented that, but his first name was Robert, not his last.. He was in-fact a Tennessee hillbilly. How is the best way to go about getting him the recognition he deserves?
Ah yes I'm familiar with this story.
On Culin's own admission (note: speaking of inaccuracies, the 102nd Cavalry Group was not a unit of the 2nd Armored Division, but rather a corps level formation in the 1st Army), he took the idea, stated awkwardly and generally from a self-described dimwitted comrade, and ran with it.
Max Hastings conveys the story in his Overlord, and while its not exactly prevalent, its out there and relatively well known among people who study the battle for Normandy and Operation Cobra in great depth.
