Holocaust is in the vernacular. At what day and hour? Who knows.
Wikipedia/truth by committee - never struck me as the ultimate source when (facts) can be bombed by deniers. But things change.

I remember the holocaust TV expose' in the mid 1950's.
Eisenhower must have had something to do with it. It was 'surreal' but I didn't know the meaning of that word at that age. I still can recall the images in black and white. My feelings were a frightened anger.
The feelings have not changed over the decades.
