@xanon I found a piece of information about Teslas on a quirky top 10 mysteries piece on netflix about 4 years ago & a man called Arthur Matthews according to the piece was Teslas secret son he Co-wrote the book Wall of light with Tesla & their connection to the Venutians. He lived in Canada and reportedly the last person who worked with Tesla before his disaperance. The photo of Arthur is like seeing Tesla himself.
