Whiston was born around 1637, probably in London, and died there some time in 1707. He was a merchant involved in overseas trade, and had connections with the Levant and Russia companies, and may well have been an East India Company stock holder. He wrote A Discourse of the Decay of Trade in 1693, at a time of commercial crisis in England. The Glorious Revolution had removed, or at least lessened, the Dutch challenge to England, but the rising Power of France was increasingly threatening English interests.
