Hon. Daphne Winifred Louise Fielding (née Vivian; 11 July 1904 – 5 December 1997) was a popular British author in the 20th century.
Daphne Vivian was born on 11 July 1904 in Westminster, London, eldest daughter of George Vivian, 4th Baron Vivian, and Barbara (née Fanning). Her parents separated when she was four years old and her father raised the children at Glynn, Cornwall, where the family were known as the 'mad Vivians'.
She married, firstly, Henry Thynne, 6th Marquess of Bath, on 27 October 1927. Neither his nor her parents approved of the marriage and they were divorced in 1953. She was known as the Marchioness of Bath. The couple had five children: her eldest daughter, Lady Caroline Jane Thynne, married David Somerset, 11th Duke of Beaufort and had issue; her eldest son, Thomas Timothy Thynne, died in infancy, whilst her second son Alexander George Thynn, became the 7th Marquess of Bath; her fourth son, Lord Christopher John Thynne, married Antonia Palmer, daughter of Sir Anthony Palmer, 4th Baronet, and had issue; whilst her youngest son, Lord Valentine Charles Thynne (1937–1979), married firstly, Veronica Jacks and had issue; he married secondly Susanne Alder and married thirdly Liese Dennis.
She moved in the world of the "Bright Young Things" in the 1920s and produced a series of popular books about high society. Of Fielding's memoirs, Mercury Presides, Evelyn Waugh wrote: "Daphne has written her memoirs. Contrary to what one would have expected they are marred by discretion and good taste. The childhood part is admirable. The adult part is rather as though Lord Montgomery were to write his life and omit to mention that he ever served in the army."
