Irving Locker just might be the most interesting man alive. At 99 years old, he’s just about seen it all. He survived five major battles in WWII, including Battle of the Bulge and D-Day. And at 18, he became one of the youngest staff sergeants in all of the Army. At 5’1”, he might be short in stature, but boy, does he have a huge heart and a story to share.
