I think that you are correct, Krosskelt and Aryi. I did not notice before you mentioned it, but I agree that he is sitting like a guest, not an owner in that chair in the first picture. He is not completely comfortable and looks as if he may jump up and leave soon.
Aryi, I mentioned the food pickiness before and agree with that also. Kind of a gourmet about what he eats, but loves to eat I think. I also agree on the love of theatre and that he was somewhat theatrical in how he came off to people as well.
I'm still getting more science like biology like Nocturne's Angel got, along with inventions. Paul said he had many interests, so we could all possibly be right.
I think the girl in the second picture was his daughter, and agree the wife was a convenience and a way to look respectable, since I still feel he was gay or asexual, and she was also a way to get money for the work he was really passionate about.
I am hearing the Fibonacci sequence. Not sure of spelling of Fibonacci (liberal arts major, can you tell, lol). Will a science person, if one is present, please correct my spelling? Thanks. I think that would be physics, right? Physics was Einstein's thing, so maybe that is why Nocturne's Angel got "the Einstein of his time".
I mentioned inventing robotics that were eventually used in space, possibly modeled on biology and how living organisms work. Could space physics be why you are getting the UFO thing, Aryi? Maybe back engineering of what we got our hands on after Roswell? I think the time period would fit.
