Big pic apologies, but, I thought it was cool enough to be seen in the large.
This pic was taken in 1927, at the
Solvay Conference, in Brussels.
It's been called the most intelligent picture ever taken.

At some point, someone colorized it. Rather well, I think. Below is a pic taken at almost the same moment, which has not been colorized.
