Frances (Fanny) Brawne Lindon (9 August 1800 – 4 December 1865) is most known for her
betrothal to nineteenth-century English
Romantic poet
John Keats, a fact largely unknown until 1878, when Keats's letters to her were published. Their engagement, lasting from December 1818 until Keats's death in February 1821, spanned some of the most poetically productive years of his life.
