Joseph Edward Gage (c.1687 – 1766) was an entrepreneur and speculator. He was the son of Joseph Gage of Sherborne Castle and Elizabeth Penruddock and the brother of Thomas Gage, 1st Viscount Gage Bt
As a young man in Paris borrowed money from Richard Cantillon to speculate in shares in Mississippi Company and the South Sea Company. He made a vast paper fortune, whereupon he offered Augustus II the Strong the King of Poland 3,000,000 pounds for his crown. When this offer was declined he made a similar offer for the crown of Sardinia. Later he was granted a silver mine, and entered into the service of the King of Spain, given the command of his armies in Sicily and Lombardy, and created a grandee (March 1743) of the first class of the kingdom of Spain.[1] He was also presented by the King of Naples with the order of San Gennaro, and a pension of 4000 ducats a year.[2] He married Lady Mary Herbert who was also involved in Gages' financial speculations. She was twice bailed out by her father, William Herbert, 1st Marquess of Powis after incurring substantial losses.
