Lady Mary Wortley Montagu, née Pierrepont, was born in London to an aristocratic English family. She was the eldest child of Evelyn Pierrepont, 1st Duke of Kingston-upon-Hull, and his first wife Mary Fielding. In 1712, she eloped with Edward Wortley Montagu, a lawyer and diplomat. She is chiefly known today for the letters she wrote while the couple were living in Constantinople (present-day Istanbul), where her husband served as the British Ambassador. Although frequently attacked during her life, her writings are now considered an extremely valuable historical resource, and the earliest secular work by a woman about the Muslim world. Her experiences in the Ottoman Empire gave her knowledge about a practice of inoculation against smallpox called variolation, which Lady Mary introduced to the West on her return. She also kept a diary (destroyed by her daughter) and wrote poems, essays, a brief epistolary novel, and a play. Her first published writing appeared in 1714 in Addison's Spectator, under the pseudonym Lady President. Her Letters and Works were published in 1837 with an introduction by her granddaughter Lady Louisa Stuart.
