There, from the fall of 1959 through the spring of 1962, Harvard psychologists, led by Henry A. Murray, conducted a disturbing and what would now be seen as ethically indefensible experiment on twenty-two undergraduates. To preserve the anonymity of these student guinea pigs, experimenters referred to individuals by code name only. One of these students, whom they dubbed "Lawful," was Theodore John Kaczynski, who would one day be known as the Unabomber, and who would later mail or deliver sixteen package bombs to scientists, academicians, and others over seventeen years, killing three people and injuring twenty-three.
