Background: Theodore John Kaczynski (; born May 22, 1942), also known as the Unabomber, is an American domestic terrorist. A mathematics prodigy, he abandoned an academic career in 1969 to pursue a primitive lifestyle, then between 1978 and 1995 he killed three people, and injured 23 others, in a nationwide bombing campaign targeting those involved with modern technology. In conjunction, he issued a social critique opposing industrialization and advancing a nature-centered form of anarchism.
Context: At Harvard, Kaczynski lived during his first year at 8 Prescott Street, which was designed to accommodate the youngest, most precocious freshmen in a small, intimate living space. The next three years he lived at Eliot House. One of his suitemates there recalled that he avoided contact with others and "would just rush through the suite, go into his room, and slam the door." Another suitemate said Kaczynski was reserved, but regarded him as a genius: "It's just an opinion - but Ted was brilliant." Other students stated Kaczynski was less socially averse than these descriptions imply; an Eliot House resident who dined with Kaczynski at times called him "very quiet, but personable ... He would enter into the discussions maybe a little less so than most [but] he was certainly friendly."  As a sophomore, Kaczynski participated in a study described by author Alton Chase as a "purposely brutalizing psychological experiment", led by Harvard psychologist Henry Murray. Subjects were told they would be debating personal philosophy with a fellow student, and were asked to write essays detailing their personal beliefs and aspirations. The essays were turned over to an anonymous attorney, who in a later session would confront and belittle the subject - making "vehement, sweeping, and personally abusive" attacks - using the content of the essays as ammunition, while electrodes monitored the subject's physiological reactions. These encounters were filmed, and subjects' expressions of rage were later played back to them repeatedly. The experiment ultimately lasted three years, with someone verbally abusing and humiliating Kaczynski each week. In total, Kaczynski spent 200 hours as part of the study. Kaczynski's lawyers later attributed his hostility towards mind control techniques to this experience. Some sources have suggested that Murray's experiments were part of the US government's research into mind control, known as Project MKUltra. Chase and others have also suggested that this experience may have motivated Kaczynski's criminal activities, while philosopher Jonathan D. Moreno has said that, while "Kaczynski's anti-technological fixation and his critique itself had some roots in the Harvard curriculum," Kaczynski's later bombing campaign can "by no means be laid at Harvard's door".  Kaczynski earned his Bachelor of Arts degree in mathematics from Harvard in 1962. He finished with an above-average 3.12 GPA but had been expected to perform better.
