David Duguid

David Duguid (1832–1907) was a Scottish spiritualist medium and Glasgow cabinet-maker by trade.
He was born in Dunfermline. He worked as a cabinet-maker as a young man. He began his interest in spiritualism in 1866 by attending table-turning experiments. He later took up mediumship and spirit photography. He was also known for his automatic drawings and paintings, which impressed the psychical researcher Frederic W. H. Myers. However, in 1878, Frank Podmore attended a séance of Duguid and strongly suspected that he had cheated by using a card that had already been painted.
His spirit photography was exposed when it was revealed he had used paper with chemically bleached-out images on them, and during his séances would secretly press the paper against a blotter dampened with a developing solution. Harry Price wrote that Duguid "was caught cheating over and over again. One of his 'extras', a 'Cyprian priestess', was found to be a facsimile of a German picture."
