The medical examiner, during the testing for arsenic, states that "they dug up Napoleon and [the test] worked on him." In 1961 (140 years after Napoleon's death), a Swedish dentist named Sten Forshufvud, Dr. Hamilton Smith of Glasgow, and Dr. Anders Wassen also of Sweden published an article in Nature magazine positing that Napoleon may have been intentionally killed by arsenic poisoning based on analysis of a lock of hair "probably taken immediately after his death." A second paper by the same team analyzed a different lock of hair also believed to be Napoleon's and suggested that the exiled emperor may have been exposed to the poison intermittently for about four months leading up to his death. Later analysis of other hair samples also included high levels of arsenic, though the origin of any of the samples is somewhat in doubt and the actual levels were reportedly inconsistent. In December 2008 (seven months after the airing of this episode, and now 187 years after Napoleon's death) a rebuttal paper by J. Thomas Hindmarch and John Savory pointed out that not only was arsenic a common medication in that time period (although Napoleon likely did not take it himself as he distrusted doctors), it was also widely used in various household and even cosmetic products (including face and hair powders, insecticides, rodenticides, clothing dyes, wallpaper dyes, and "even candy wrappers," and may have also been in coal smoke used for heating the emperor's chambers and in the water supply) and would have been laced through the soil he was buried in, suggesting a more innocent, natural reason for the levels of arsenic found in Napoleon's hair samples. They also pointed out that the 19th-century practice of preserving locks of hair as mementos involved arsenical solutions, yet another possible source of the high arsenic levels (and the one the authors of this paper held as most likely). A study conducted around the same time (187 years after Napoleon's death) by physicists from the University of Milano-Bicocca and the University of Pavia (in conjunction with toxicologists) studied preserved samples of hair from throughout Napoleon's life (from boyhood to death) and from various family members including his son and the Empress Josephine (provided by the Glauco-Lombardi Museum in Parma (Italy), the Malmaison Museum in Paris and the Napoleonic Museum in Rome) and concluded that the arsenic levels found in Napoleon's hair was the result of the constant absorption of arsenic from his environment throughout his life, that there was no significant difference between the arsenic levels when he was a boy and when he died, and that the level of arsenic in the 200-year-old samples, while considered dangerous today, were apparently quite normal by the standards of the time (Clemenza M, Fiorini E, Guerra C, Herborg C, Labra M, Orvini E, et al. Misure con attivazione neutronica sulla presenza di arsenico nei capelli di Napoleone Bonaparte e di suoi famigliari. Il Nuova Saggiatore 2008).
