Sten Gabriel Bernhard Forshufvud (9 February 1903 – 25 June 1985) was a Swedishdentist and physician, and amateur toxicologist (expert on poisons) who formulated and supported the controversial theory that Napoleon was assassinated by a member of his entourage while in exile. He wrote a book, in Swedish, about this in 1961, which was translated the following year as ''Who Killed Napoleon?'' He later published his ideas in English in the 1983 book ''Assassination At St. Helena: The Poisoning Of Napoleon Bonaparte,'' written in collaboration with Ben Weider, co-author (with David Hapgood) of the 1982 book ''The Murder Of Napoleon,'' which also advanced Forshufvud's theories.
