Theoore John Kaczynski (born May 22, 1942), known as the Unabomber, is an American mathematician who carried out a campaign of bombings and mail bombings which killed three people and wounded 23. He sent bombs to several universities, airlines, and other targets from the late 1970s through the mid-1990s. Kaczynski sent a letter on April 24, 1995 to The New York Times, promising "to desist from terrorism" if the Times or a similarly respected news journal would publish his manifesto. In his Industrial Society and Its Future (commonly called the "Unabomber Manifesto," described below) he argued that his actions were a necessary (although extreme) tactic by which to attract attention to the erosion of human freedom necessitated by modern technologies requiring large-scale organization.
