Terrorism via mail and hand-delivered bombs across the United States, 1978–1995
Theodore John Kaczynski was born on May 22, 1942, in Chicago, Illinois, USA. He would go on to become one of the most notorious domestic terrorists in American history, known universally by his FBI-assigned alias, the Unabomber. The nickname itself derived from the FBI's internal case designation "UNABOM" — a reference to the universities and airlines that were targeted throughout his long campaign of violence.
Kaczynski was a Harvard-educated mathematician, a background that underscored the disturbing paradox at the center of his case: a man of exceptional academic achievement who turned his intellect toward the construction and delivery of deadly explosive devices. His case remains one of the most studied examples of domestic terrorism in the United States, not least because of the intellectual framework he constructed to justify his crimes.
Kaczynski's bombing campaign ran from 1978 to 1995 — a period of 17 years during which he mailed and hand-delivered explosive devices to targets he associated with universities, airlines, and modern technology. The attacks occurred across the United States, and the FBI's case name, UNABOM, reflected the two primary categories of target: universities and airlines.

Første bombe sendt
Kaczynskis bombekampagne indledes i 1978, da han sender sin første håndlavede brevbombe til et mål knyttet til teknologi og modernisering.
Kampagnen intensiveres
I løbet af 1980'erne sender Kaczynski fortsat bomber til universiteter og flyselskaber; angrebene efterlader et stigende antal sårede.
Kampagnens afslutning og Manifestet
Bombekampagnen kulminerer i 1995, og Kaczynskis manifest — som beskriver hans ideologiske modstand mod teknologi og modernisering — bliver en central drivkraft i efterforskningen og mediernes dækning.
Over the course of his campaign, Kaczynski killed 3 people and injured 23 others. His method was meticulous and deliberate: each device was handcrafted and delivered in a way designed to reach specific individuals connected to institutions or industries he viewed as representative of a technological society he had come to despise. The bombings were spread across nearly two decades, making the investigation one of the longest and most resource-intensive in FBI history.
The FBI case name "UNABOM" eventually produced the public alias by which Kaczynski became infamous. As reported by Oxygen, the nickname "Unabomber" emerged directly from that internal FBI designation, and it stuck in media coverage for the remainder of the investigation and well beyond.
Over the 17-year campaign, Kaczynski's victims numbered 3 killed and 23 injured. His targets were connected to universities, airlines, and the broader world of modern technology — institutions and industries that Kaczynski appears to have viewed as emblematic of a technological civilization he opposed. The research available does not provide the individual names or detailed profiles of each victim, but the confirmed toll of 3 deaths and 23 injuries establishes the measurable human cost of his campaign.
Anholdelse
Ted Kaczynski anholdes den 3. april 1996 efter 17–18 års terror; hans bror David Kaczynski havde henvendt sig til FBI med afgørende oplysninger.
Skyldig-erkendelse og dom
Kaczynski indgår en skyldig-erkendelse i føderal domstol og idømmes fire på hinanden følgende livstidsstraffe plus 30 år.

The geographic spread of the attacks across the United States meant that Kaczynski's campaign generated fear well beyond any single community or institution. The prolonged nature of the bombing campaign — nearly two decades — meant that the threat remained active and unresolved for an extraordinarily long time, compounding the psychological impact on potential targets and the wider public.
The FBI investigation into the Unabomber was among the longest and most expensive in the bureau's history. After 17 years of bombings, authorities tracked Kaczynski to a remote cabin in Montana, where he was arrested in April 1996. The breakthrough that led investigators to him came in part through his own writings — a lengthy manifesto he had demanded be published, which ultimately helped identify him.
Following his arrest, Kaczynski faced federal prosecution. In January 1998, he pleaded guilty to 13 federal charges. He was sentenced to life in prison without the possibility of parole. The research does not specify the exact statute numbers under which he was convicted.
Kaczynski remained incarcerated until his death. He died on June 10, 2023, marking the end of one of the most closely watched criminal cases in modern American history.
The Unabomber case has attracted substantial documentary and media attention over the decades. The most prominent documentary is Unabomber: In His Own Words (2020), which premiered on Discovery Channel Canada and was distributed internationally via Netflix. The production drew directly on Kaczynski's own writings and statements, offering an account structured around his own perspective on his actions and ideology. Coverage of this documentary can be found via Netflix's own promotional material and reporting.
Additional documentary coverage includes The FBI Files: "The Unabomber", an episode of the long-running History Channel series, available on YouTube through the FBI Files channel. Further documentary treatments include Notorious: Episode 1 — Ted Kaczynski, available on DocPlay, and Who Was the Unabomber?: The Story of Ted Kaczynski, distributed by Real Stories and accessible on YouTube.
The breadth of documentary coverage reflects the enduring public fascination with the case — its duration, the intellectual profile of the perpetrator, and the ideological dimension of the crimes have made it a recurring subject for filmmakers and journalists across more than two decades.
