Pierre Gilliard

Decades later, DNA tests were carried out in 1995, which proved that Anderson was not Anastasia, but was a Polish woman by the name of Franziska Schanzkowska.

In 1958, Gilliard was severely injured in a car accident in Lausanne. He never fully recovered and died four years later on 30 May 1962.

In 1920, he returned to Switzerland via the Russian Far East. He became a French professor at the University of Lausanne and was awarded the French Legion of Honor. In 1921, he published a book entitled Le Tragique Destin de Nicholas II et de sa famille, which described the last days of the Tsar and his family, and the subsequent investigation into their deaths.

Gilliard remained in Siberia after the murders of the family, assisting White Russian investigator Nicholas Sokolov. He married Alexandra "Shura" Tegleva, who had been a nurse to Grand Duchess Anastasia Nikolaevna of Russia, in 1919. In Siberia, he was instrumental in unmasking an impostor who claimed to be the Tsarevich Alexei.

Pierre Gilliard was born on 16 May 1879 in Fiez, Switzerland. In his memoirs, Gilliard wrote that he initially came to Russia in 1904 as a French tutor to the family of Duke George of Leuchtenberg, a cousin of the Romanov family. He was recommended as a French tutor to the Tsar's children and began teaching the elder children, Grand Duchesses Olga and Tatiana Nikolaevna of Russia in 1905.
