Nan Ino Cooper, Baroness Lucas

Nan Ino Cooper, born on 13 June 1880 in Blandford, Dorset, was a British nurse and educator who held the titles of 10th Baroness Lucas and 6th Lady Dingwall. She was the daughter of Auberon Edward William Molyneux Herbert and Florence Amabell (Cowper) Herbert.

Her early interests included mystical and occult religions; she was known to be an ardent theosophist. During her lifetime, she was involved in various activities related to theosophy and spiritualism. Notably, she donated a house in the New Forest, which she inherited, to the 'Purple Lotus Mother' of the 'Universal Brotherhood' to serve as a theosophist school.

In her professional life, Cooper served as a nurse, having trained in nursing prior to World War I. During the war, she managed her family estate, Wrest Park, which she operated as a hospital for wounded soldiers. This occurred before the outbreak of the war in 1914. She also held the position of director at the Cuba Raja Yoga School in Cuba during the early 1900s, where she resided for some time.

Within her family, she managed Wrest Park during her brother Auberon Herbert, 9th Baron Lucas's lifetime. In her capacity as a collector and benefactor, she inherited a significant collection of over 3,000 prints and drawings assembled by Amabel Hume-Campbell, 1st Countess de Grey, and her nephew Thomas de Grey, 2nd Earl de Grey. In memory of her brother, who died of wounds sustained as a fighter pilot during World War I, she donated this collection to the British Museum. She also retained another collection related to the history of printmaking, including mezzotints and stipples, which was later sold at auction along with the contents of Wrest Park.

In the early 1920s, Lady Lucas donated a collection of fossils, primarily from the Isle of Wight, to the Natural History Museum.

She succeeded to her titles in 1916 following her brother Auberon Thomas Herbert. On 30 April 1917, she married Lieutenant-Colonel Howard Lister Cooper. They had two children: Anne Rosemary Cooper and Rachel Cooper. Rachel married Spencer Loch. Lady Lucas passed away on 3 November 1958. Her elder daughter inherited her titles, and her younger daughter had three children.
