Thanks so much for these reflections, Tom. My impression--and it is hard to put my finger on what gives me this impression, so it should be taken with a heavy grain of salt--is that Albrecht had a difficult personality. I think I sense this mainly from the discussions that arise whenever he is getting an apprentice. I would love to know more about what this was about:
Related issues arose in 1771 when William Henry, the former gunsmith who was now a prominent Lancaster merchant, apprenticed his eldest son to Albrecht: “because [William Henry] intends to place his son in an apprenticeship with [Albrecht], we thought that it would be good to speak directly and honestly with Henry, so that he consider it carefully, so that we should not get the blame and Henry should not be offended.”
But all we have is that mysterious note from Moravian records. Authorities seem to be taking special care to make sure parents are well informed before they give their son as an apprentice to Albrecht. So this could have something to do with Albrecht--or just with the apprentice system generally. But, as you say, he seems to have had friction with previous apprentices ....
