Wachtmeister, Countess Constance Georgina Louise (née de Bourbel de Monpiçon; 1838-1910).
A close friend of Helena P. Blavatsky, Wachtmeister was born on March 28, 1838, in Florence, Italy. Her parents were the Marquis de Bourbel, formerly of the French diplomatic service, and Constance Bulkley. She lost her parents when she was very young and was sent to an aunt in England, where she lived and in 1863 married a cousin, Count Karl Wachtmeister, then Swedish and Norwegian minister at the Court of St. James. After three years, they moved to Scandinavia, where her husband served as a government minister in Copenhagen and Stockholm. Wachtmeister was widowed in 1871. She had one son, Count Axel Raoul, a well-known musical composer in his day.
Wachtmeister joined the Theosophical Society in 1881 and met H. P. Blavatsky in London in April 1884. She was secretary and treasurer of the Blavatsky Lodge in London and also worked for the Theosophical publishing company there, contributing generously to its funds. In 1887, Wachtmeister, the Keightleys, and Blavatsky acquired a large house at 17 Lansdowne Road, London, where Blavatsky continued to write The Secret Doctrine.
