I live in a North Wales village and the next village, Rhuddlan, was home to Philip Jones Griffiths a Magnum photographer renowned for his work in the Vietnam war, Malaya and the Irish troubles also of the Beatles. Refused admission to the US in the 1970's by Richard Nixon for his portrayal of the war. I didn't even know who this man was, of which I am now ashamed.
Interestingly, his image of GI's showing compassion to a wounded Vietcong soldier was used in a scene of Apocalypse Now. His family were upset at his portrayal in the film as that of a blase photographer, when he was in fact a shy retiring man.
His life history was presented by a school friend of Phillip Griffiths who is promoting his life in a series of photographic lectures. He died in 2008.
I often used to visit Washington DC in the 1980s and many of the homeless people round one of the metro stations were said to be ex Vietnam veteran soldiers, (was the station Foggy Bottom?). The time was the start of the Aids problem and I often think back and wonder how many of those people made it this far. Not a lot I guess. Truly, there were a lot of still in progress after effects.
