“ MENDES, FERNANDO, M.D. (d. 1724) , physician, was born of Jewish parentage in the province of Beira, Portugal. He graduated M.D. at Montpellier in December 1667, and became physician to John IV of Portugal. When Catherine of Braganza was on her way to England to become the wife of Charles II, she was attacked during her journey through New Castile with erysipelas, and Mendes was sent to her assistance. He gained such favour with the princess that she made him a member of her household, and desired him to accompany her to England and settle there. ”
