Dictionary of National Biography, 1885-1900/Gammon, James
GAMMON, JAMES (fl. 1660–1670), engraver, is known by a few works, which, though they possess little merit as engravings, are valued for their rarity. They are for the most part poor copies of better known engravings. Gammon resided in London, and was employed by the booksellers. Among his engravings were portraits of James I, Charles I, Charles II, Catherine of Braganza, James, duke of York, Henry, duke of Gloucester, Mary, princess of Orange, Duke and Duchess of Monmouth, Richard Cromwell, George Monck, Duke of Albemarle (a copy from Loggan's print), Sir Tobias Mathew (prefixed to his ‘Letters,’ 1660), Edward Mascall the painter, and others. A portrait of Ann, duchess of Albemarle, was engraved by a Richard Gammon ‘against Exeter House in ye Strand,’ probably a relative of James.
