Alison Des Forges, 66, Human Rights Advocate, Dies

The MacArthur Foundation recognized her work with a $375,000 “genius” grant in 1999. Her authoritative book, “Leave None to Tell the Story: Genocide in Rwanda,” was published that year.

On its Web site, the United States Holocaust Memorial Museum said Dr. Des Forges’ book provides “a meticulously detailed description of the organization of the campaign that killed some half million Tutsi,” adding that it “analyzes the failure of the international community to intervene in the genocide.”
