Anna Anderson (16 December 1896 12 February 1984) was the best known of several impostors who claimed to be Grand Duchess Anastasia of Russia. The real Anastasia, the youngest daughter of the last Tsar and Tsarina of Russia, Nicholas II and Alexandra, was murdered with her parents and siblings on 17 July 1918 by Bolsheviks in Ekaterinburg, Russia, but the location of her body was unknown. In 1920, Anderson was institutionalized in a mental hospital after a suicide attempt in Berlin. At first, she went by the name Fräulein Unbekannt (German for Miss Unknown) as she refused to reveal her identity. Later she used the name Tschaikovsky and then Anderson. In March 1922, claims that Anderson was a Russian grand duchess first received public attention. Most members of Grand Duchess Anastasia's family and those who had known her, including court tutor Pierre Gilliard, said Anderson was an impostor but others were convinced she was Anastasia. In 1927, a private investigation funded by theTsarina's brother, Ernest Louis, Grand Duke of Hesse, identified Anderson as Franziska Schanzkowska, a Polish factory worker with a history of mental illness.
