There is an uncorroborated story that AH himself visited England in 1912.
The unverifiable story was in a book I read some years ago.
Apparently that 23 year-old "paperhanger" obtained passage to
GB in 1912 to visit his relations in Liverpool.
If true, I wonder if that was the reason AH was so reticent
to invade England in 1940. he might have found the English
mists and fog disorienting.
