Eleanor (Nora) Mildred Sidgwick was born in Whittingehame, East Lothian on 11 March 1845 to Lady Blanche Harriet and James Maitland Balfour. She died at Fisher's Hill, near Woking on 10 February 1936. Her early schooling fell to her mother, who introduced her to literature, history, geography and mathematics. Bible study, travel and disputations with her siblings (especially, her brother Arthur J. Balfour) supplemented her education. From an early age she developed a keen interest in the higher education of women and the study of psychical phenomena (e.g. ghosts, apparitions, mediums, telepathy, and so on); throughout her life she was a vigorous promoter of both. She lectured, published pamphlets and books on these and other topics, including physics. She held honorary degrees from Manchester, Birmingham, St Andrews and Edinburgh.
