It seems likely that Caldwell was afflicted with impetigo although we are told the nickname came from his unusually colored beard. He must have been a dynamic character, his name comes up as the “go to” guy in the accounts of his peers.
I wonder if the author meant "vitiligo."
Indeed I did, tks. Changed it in the original. my free time on the Fire is if I wake up early, didn’t take the time to Google it.
