What parts of occult practices was Henry most interested in? I've heard the talk of performing séances, but I was curious as to if it went deeper than that.
Was it common for people to attribute his vast success to the occult?
I've heard that he had quite a few prestigous people joining him in these things. JD Rockefeller is one, but I was wondering if anybody knew of any other names pegged to this? Perhaps, if nothing else, his other Standard Oil business partner, Samuel Andrews?
Thanks in advance!
