Duncan Campbell (1680?-1730) was a Scottish deaf man and professed soothsayer.
The account of Campbell's early life, brought up in Lapland where his Scottish father had wed a local woman, has been questioned. He had some teaching at the University of Glasgow, according to the recommendations of John Wallis.
Campbell went in 1694 to London, where his predictions attracted attention in fashionable society. Running into debt, he went to Rotterdam, where he enlisted as a soldier. Returning in a few years to London, he read a wealthy young widow's fortune, to his own benefit, and having taken a house in Monmouth Street, he found himself again a centre of attraction.
Campbell succeeded in obtaining the notice of royalty, as reporting in the Daily Post of Wednesday, 4 May 1720: "Last Monday Mr. Campbell, the deaf and dumb gentleman—introduced by Colonel Carr—kissed the king's hand, and presented to his majesty The History of his Life and Adventures, which was by his majesty most graciously received."
Daniel Defoe was an English novelist, journalist, merchant, pamphleteer and spy. He is most famous for his novel Robinson Crusoe, published in 1719, which is claimed to be second only to the Bible in its number of translations. He has been seen as one of the earliest proponents of the English novel, and helped to popularise the form in Britain with others such as Aphra Behn and Samuel Richardson. Defoe wrote many political tracts, was often in trouble with the authorities, and spent a period in prison. Intellectuals and political leaders paid attention to his fresh ideas and sometimes consulted him. Defoe was a prolific and versatile writer, producing more than three hundred works—books, pamphlets, and journals—on diverse topics, including politics, crime, religion, marriage, psychology and the supernatural. He was also a pioneer of business journalism and economic journalism.
