Ted Kaczynski, the man known as the Unabomber, died on Saturday at the age of 81. Kaczynski was a former mathematics professor who carried out a 17-year bombing campaign against people he believed were advancing modern technology and the destruction of the natural environment. He was arrested in 1996 after his brother recognized his writing style in the Unabomber Manifesto, a 35,000-word treatise on his anti-technology philosophy. Kaczynski pleaded guilty to the bombings in 1998 and was sentenced to life in prison.
