Kersey, John

, deserves mention as having been the author of a book on “The Elements of Algebra,” one of the clearest and most comprehensive of the kind in any language but nothing is known of his personal history. He also published an improved edition of “Wingate’s Arithmetic” and a “Dictionarium Anglo-Britannicum, or | General English Dictionary.” He lived in the reign of Charles the Second; and a head of him, by Faithorne, finely engraved, is prefixed to his algebra. 1
