Elizabeth Sanderson Haldane was born in Edinburgh on 27 May 1862 and died at St Margaret's Hospital in Auchterarder, Perthshire on 24 December 1937. She was the only daughter of Robert Haldane, of Cloanden (later called Cloan), Auchterarder by his second wife, Mary Elizabeth Burdon Sanderson, second daughter of Richard Burdon-Sanderson, of West Jesmond and Otterburn Dene, Northumberland. She was a younger sister of the Hegelian idealist philosopher, lawyer, and statesman Richard Burdon Haldane (from 1911, 1st Viscount of Cloan) and the physiologist and philosopher John Scott Haldane. Elizabeth Haldane was educated in a strongly evangelical and highly cultivated household, where she shared her brothers' tutors as well as their intense interest in philosophy. At about the age of fifteen she attended private school in Edinburgh, where she excelled in languages, literature and mathematics.
