Night Photography Historians
I incorrectly wrote that Brandt's nighttime images of the blacked out London during WWII were published in 1938. But only Fotoholik pointed out that WWII didn't start until 1939.
I looked into this a little further. Brandt's book A Night in London was published in 1938. But his photographs of London during the blackout were, obviously, not included in that book. St. Paul's Cathedral was taken in 1942. So, now the question is, in what book were his WWII photographs published? I don't know.
If anyone knows, please let me know.
