Photo depicting screening of apprentices in a steel plant in Mannheim, Germany, in 1939. As far as I can tell the chap standing with his back to us, resting his arms on the equipment, would squat down and peer into the machine (just where his hands are) at the chest of each young man in turn. Which means he was staring straight into the xray tube, with on the apprentice and the fluoro screen between him and it.
Every time I see a photo like this I go through the same mental cascade.
- Huh? Crazy. What sort of lunatic would stare into an xray tube hours at a time? They must have been cretins.
- Hmmm... hang on.. we are probably no smarter than they were; they just didn't know any better.
- Errr... what will folk in 80 years time be looking at that we are doing today with the same thoughts?
