Mata Hari's body was not claimed by any family members and was accordingly used for medical study. Her head was embalmed and kept in the Museum of Anatomy in Paris, but in 2000, archivists discovered that the head had disappeared, possibly as early as 1954, when the museum had been relocated. Records dated from 1918 show that the museum also received the rest of the body, but none of the remains could later be accounted for.
