Also known as the infamous Unabomber, Kaczynski is a primitivist who took his criticisms of civilization and technology to the extreme. Although he had a promising academic career, he eventually quit his professorship at the University of California at Berkeley to live in a remote cabin without running water or electricity in the wilds of Montana. There, Kaczynski began his bombing campaign, sending 16 bombs to targets including universities and airlines, killing three people and injuring 23. The rationale for his actions are outlined in his manifesto, titled "Industrial Society and Its Future." He is serving life without parole in a federal prison.
