Because he targeted universities and airlines, the FBI had dubbed him the Unabomber, reports the Associated Press: Theodore "Ted" Kaczynski, the Harvard-educated mathematician who retreated to a dingy shack in the Montana wilderness and ran a 17-year bombing campaign that killed three people and injured 23 others, died Saturday. He was 81... Kaczynski died at the federal prison medical center in Butner, North Carolina, Kristie Breshears, a spokesperson for the federal Bureau of Prisons, told The Associated Press. He was found unresponsive in his cell early Saturday morning and was pronounced dead around 8 a.m., she said. A cause of death was not immediately known. Before his transfer to the prison medical facility, he had been held in the federal Supermax prison in Florence, Colorado, since May 1998, when he was sentenced to four life sentences plus 30 years for a campaign of terror that set universities nationwide on edge. He admitted committing 16 bombings from 1978 and 1995, permanently maiming several of his victims. Years before the Sept. 11 attacks and the anthrax mailing, the "Unabomber's" deadly homemade bombs changed the way Americans mailed packages and boarded airplanes, even virtually shutting down air travel on the West Coast in July 1995. He forced The Washington Post, in conjunction with The New York Times, to make the agonizing decision in September 1995 to publish his 35,000-word manifesto, "Industrial Society and Its Future," which claimed modern society and technology was leading to a sense of powerlessness and alienation. [The Post published it "at the urging of federal authorities, after the bomber said he would desist from terrorism if a national publication published his treatise."] But it led to his undoing. Kaczynski's brother David and David's wife, Linda Patrik, recognized the treatise's tone and tipped off the FBI, which had been searching for the "Unabomber" for years in nation's longest, costliest manhunt. Authorities in April 1996 found him in a 10-by-14-foot (3-by-4-meter) plywood and tarpaper cabin outside Lincoln, Montana, that was filled with journals, a coded diary, explosive ingredients and two completed bombs. A psychiatrist who interview him in prison said Kaczynski suffered from persecutorial delusions, the article points out. "I certainly don't claim to be an altruist or to be acting for the 'good' (whatever that is) of the human race," Kaczynski wrote on April 6, 1971. "I act merely from a desire for revenge." A stand-up comic once joked that the only technology that Kaczynski didn't have a problem with....was bombs.
