The Unabomber case, also known as the “Unabomber Manifesto,” refers to a series of bombings that occurred across the United States between 1978 and 1995. The Unabomber was a domestic terrorist who targeted individuals associated with technology and industry, killing three people and injuring 23 others.


The Unabomber’s first known attack occurred in May 1978, when he sent a mail bomb to Northwestern University. The bomb was addressed to a professor, but it was intercepted and defused before it could detonate. Over the next several years, the Unabomber sent a series of bombs to various individuals and institutions, including airlines, computer stores, and universities. Despite a massive investigation by the FBI, the Unabomber remained at large for nearly two decades.

In 1995, however, the Unabomber sent a manifesto to The New York Times and The Washington Post, threatening to continue his attacks unless the manifesto was published in full. The manifesto, titled “Industrial Society and Its Future,” railed against modern technology and its impact on society, calling for a return to a primitive way of life. After the manifesto was published, the Unabomber’s brother recognized its style of writing and contacted the FBI, leading to the Unabomber’s eventual arrest.


In 1996, Ted Kaczynski, a former mathematics professor, was arrested at his remote cabin in Montana. He was charged with multiple counts of murder and terrorism, and in 1998 he pleaded guilty to all charges. Kaczynski is currently serving a life sentence in federal prison.

The Unabomber case was notable for its long duration, the wide range of targets, and the use of mail bombs, which made it difficult for investigators to identify a suspect. The case also raised questions about the use of technology and its impact on+ society, which continue to be debated today.



The Unabomber, also known as Theodore Kaczynski, is a notorious American domestic terrorist who carried out a series of bombings in the United States between 1978 and 1995. The bombings killed three people and injured 23 others. Kaczynski’s reign of terror ended in 1996 when he was arrested in his remote cabin in Montana.
Theodore Kaczynski was born in Chicago, Illinois, in 1942. He was a gifted child and enrolled in Harvard University at the age of 16. Kaczynski received his bachelor’s degree in mathematics from Harvard and later went on to earn a Ph.D. in mathematics from the University of Michigan.
In 1967, Kaczynski became an assistant professor at the University of California, Berkeley. However, he quickly became disillusioned with academic life and resigned from his position in 1969. Kaczynski then moved to a remote cabin in Montana, where he lived a hermitic life for the next 25 years.
Beginning in 1978, Kaczynski carried out a series of bombings targeting universities and airlines. The first bombing occurred on May 25, 1978, at Northwestern University, where a security guard was injured. Over the next 17 years, Kaczynski carried out 16 bombings, targeting universities, airlines, and other institutions that he believed represented technology and modernity. Kaczynski’s targets included executives and employees of computer and engineering firms, university professors, and a passenger on an airplane.
Kaczynski’s bombs were designed to be difficult to detect and disarm. He built them using materials such as wood, nails, and pipe, and sent them through the mail or left them in public places. Kaczynski also sent letters to the media and authorities, taunting them with clues about his identity and the locations of his bombs. In one of his letters, Kaczynski wrote, “I am not motivated by money or politics. I am motivated by a desire to cause the collapse of modern industrial society.”
Despite a massive manhunt by the FBI, Kaczynski remained at large for nearly 20 years. In 1995, Kaczynski sent a 35,000-word manifesto, titled “Industrial Society and Its Future,” to the New York Times and the Washington Post. The manifesto outlined Kaczynski’s philosophy of anarcho-primitivism, which advocated for a return to a more primitive way of life and the rejection of modern technology.
Kaczynski’s brother recognized his writing style in the manifesto and contacted the FBI. In 1996, Kaczynski was arrested at his cabin in Montana, where authorities found bomb-making materials and a wealth of evidence linking him to the bombings.
In 1998, Kaczynski pleaded guilty to all charges against him and was sentenced to life in prison without the possibility of parole. In his sentencing statement, Kaczynski claimed that his bombings were “necessary to attract attention to the erosion of human freedom necessitated by modern technologies requiring large-scale organization.”
The Unabomber case is significant not only because of the severity and scope of the bombings but also because of Kaczynski’s radical philosophy and his belief that technology and modernity were destroying the natural world and human freedom. Kaczynski’s actions and ideas have had a lasting impact on discussions about the role of technology in society and the relationship between humans and the environment.
