Haldane was persuaded by
Octavia Hill to apply to the system of property administration which Hill had developed in
London to the situation in Edinburgh and in 1884, at the age of 21, she became convener of the Housing Committee of the Edinburgh Social Union. She took nursing courses in the 1880s and subsequently became involved in establishing the Voluntary Aid Detachment (VAD) from 1908 onwards. She became a manager of Edinburgh Royal Infirmary around 1901 onwards. Her autobiography,
From One Century to Another covers the period from 1862 to 1914. It provides a picture of what it was like to be a well-to-do lady in the Victorian and Edwardian periods. She was intimate with royalty such as
Queen Alexandra and was a personal friend of literary figures such as
Matthew Arnold and
George Meredith. She was taken out to dinner by Matthew Arnold who astonished her "by his knowledge of the neighbouring fishing streams, since he did not personally know the neighbourhood." George Meredith visited Cloan House in September 1890. Haldane was an accomplished translator and put her considerable talents to use translating works of philosophy, including treatises by
Descartes and
Hegel. Along with G. R. T. Ross, she translated Descartes in a two-volume set, entitled
The Philosophical Works, for
Cambridge University Press in 1911. In 1919 she sat on the
College of Nursing Salaries Committee where she was instrumental in securing a grant from the
Carnegie Trust to support the creation of their Nursing Library. In 1920, she became the first female Justice of the Peace in Scotland. == Later life and death ==
