William Jacob

William Jacob (c. 1761 – 17 December 1851 with a subsequent election to Rye for the period 1808–11.

During 1806-7 Britain temporarily invaded the region of Rio de Plata, disrupting the Spanish control of its American colonies. At this time William Jacob was a key influencer in advocating Britain's attempt at invasion and overthrow of the weak Spanish control over its American empire. In encouraging this undertaking William Jacob introduced the act of Parliament that reduced the monopoly of the South Sea Company.

In anticipation of changes in South America the firm of J&W Jacob, of Newgate Street, London embarked upon an ambitious trade. In 1807 they sought investors for an expedition to the South Seas to trade contraband fabrics with the closed colonies of Spain's American empire. The Jacobs obtained sufficient investment for three ships to proceed to the Pacific coast, the ship's being the Hero, Pandour, and Memphis. These vessels were registered as whalers and he is listed as having a fourth whaling vessel, the Invention.

While each of the ships were commissioned with letter of marque their primary role was to trade British fabrics for silver, gold or copper ingots. The three vessels were captured off Lima and resulted in an insurance claim that saw Jacob charged with fraud. He spent six months in Spain and, by 1811, was bankrupt.

Later life

He left London and took up residence at Chesham Lodge in Surrey where he became a farmer. He was later appointed comptroller of corn returns for the Board of Trade. He retired from that position in 1841 and died at his home, 31 Cadogen Place, Sloane Street, London, on 17 December 1851.

William Jacob outlived a son, the barrister and legal writer Edward Jacob (1795/6–1841). An obituary in The Gentleman's Magazine gave William's age as 89. According to Joshua Wilson, Jacob had become by 1806, “a commercial man of considerable credit” and was “one of the few Englishmen who, in the present day had carried on a direct trade with South America.”
