What strange hobby did William Lyon Mackenzie king have?

Answer 1

Privately, he was highly eccentric, with his preference for communing with spirits, including those of Leonardo da Vinci, Sir Wilfrid Laurier, his dead mother, and several of his Irish Terrier dogs, all named Pat except for one named Bob. He also claimed to commune with the spirit of the late President Roosevelt. He sought personal reassurance from the spirit world, rather than seeking political advice. Indeed, after his death, one of his mediums said that she had not realized that he was a politician. King asked whether his party would win the 1935 election, one of the few times politics came up during his seances. His occult interests were kept secret during his years in office, and only became publicized later. Historians have seen in his occult activities a penchant for forging unities from antitheses, thus having latent political import. In 1953, Time stated that he owned-and used-both an Ouija board and a crystal ball.
