I'm not suggesting that Bessler was gay, far from it. In fact he got his wife preganant before he had even met her father, the mayor, then after she died several years later, he got his best friend the Court blacksmith's 16 year old daughter pregnant and had to marry her too.
Another question - in his Apologia Poetica, he writes ' At about this time I began to run short of money, and so I turned to doctoring again. Thank God I was never short of a Frenchman or suchlike whose good nature I was able to influence, with my high-flown style of speech, to help me broaden my purse in return for having his fires quenched'. The word used in German is Frantzmann, which translates into Frenchman, but apparently in the 18th century it was a derogatory term, but I cannot find why or to whom it was applied. It is dangerous to try to read between the lines but I assume he had some health condition which caused pain and soreness and which Bessler could alleviate with some kind of ointment - or what? Anyway Frantzmann is definitely pejorative and generally aimed at the nobility which would agree with Bessler's use of 'high-flown style of speech'.
So devious must be added to his personal repetoire, although to be fair, life was rough in those times and to get aywhere you had to be tough and resourceful. Bessler was certainly that and he might just have made it to the top... unfortunately it didn't happen and he was judged a dispicable fraud and he disappeared into the fog of history, abandoned, in poverty and still designing machines, which bore slight similarities to his original perpetual motion machine.
