Discharged from the army in December of 1969 with a "service connected nervous disorder", we later came to know his problem as Post Traumatic Stress Disorder.
My pre-war brother, a normal and well-adjusted person became, according to the US Veterans' Administration, 50% disabled. He took his own life ten years later.
Twenty-five years after his death, I discovered among his belongings, a memo pad that revealed the names and addresses of his wartime friends, some of whom, with diligence, I managed to contact – 35 years after the war. Through the remembrances of his wartime friends and through my own journeys to Vietnam in 2007 and 2008, I retraced Gary's "footsteps" using his letters and photographs as guides. I continue to make discoveries about wartime in Vietnam as experienced by its veterans. The visual record of those experiences continues to unfold.
