General contextThe citation for Gray's election to the Royal Society states that he worked for the The Navy Office. The Navy Office were responsible for the construction and maintenance of Navy ships in the Royal Dockyards.

Sources in the Colonial Office papers held by the UK National Archive identify John Gray as a factor for the South Sea Company at Cartagena. The South Sea Company (officially The Governor and Company of the merchants of Great Britain, trading to the South Seas and other parts of America, and for the encouragement of the Fishery) was a British joint-stock company founded in 1711, created as a public-private partnership to consolidate and reduce the cost of the national debt. To generate income, in 1713 the company was granted a monopoly (the Asiento) to supply enslaved African pepole to the islands in the 'South Seas' and South America. Company stock rose greatly in value as it expanded its operations dealing in government debt, and peaked in 1720 before suddenly collapsing to little above its original flotation price. The notorious economic bubble thus created, which ruined thousands of investors, became known as the South Sea Bubble.
