 The woman who is today most commonly known as Harriet Taylor or Harriet Taylor Mill was born Harriet Hardy in London in October  1807.[1]  She married the pharmaceuticals wholesaler John Taylor on 14 March 1826; she was eighteen and he twenty-nine. The couple had three children: Herbert, born in 1827; Algernon (“Haji”), born in 1830; and Helen (“Lily”), born in 1831. John Taylor died of rectal cancer in 1849, and in the spring of 1851 Harriet was married again, this time to John Stuart Mill. She suffered from various health problems affecting her nervous and respiratory systems. In 1841, for instance, she lost much of the use of her legs for an extended period (J. S. Mill, [TEL], 486–7). A tuberculosis sufferer, as was John—it is possible that she caught “consumption” from him (see Packe 1954, 360)—she died of a respiratory failure on 3 November 1858.
