Gertrude Aretz, née Kuntze-Dolton, was a German historian and publisher who specialized in biographies of famous female historical figures. In 1912, she published her first book, Die Frauen um Napoleon (Napoleon and His Women Friends) under the name Gertrude Kircheisen. It was followed by works on Madame de Staël, Elisabeth Charlotte, Princess Palatine (known in German as Liselotte von der Pfalz), and others. She also wrote for popular science journals. In 1927, she published the memoirs of Countess Charlotte von Kielmannsegg, an extravagant German noblewoman who was a lover -- and perhaps secret agent -- of the Emperor Napoleon. Gertrude Aretz also wrote The Elegant Woman, From the Rococo Period to Modern Times (1932). She was married first to the Napoleonic historian Friedrich Max Kircheisen and later to the publisher Paul Aretz.
