At times, Unabomber’s story is so intense and unexpected that it’s hard to believe it’s true crime. However, the film is indeed inspired by true events. Use our guide to find the true story behind Netflix’s Unabomber.
Who Was the Unabomber?
The Unabomber is one of the most notorious figures in American true crime history. Nearly everyone has heard of the story, considering he sparked one of the longest and largest manhunts in U.S. history. The criminal case began on May 25, 1978, when Northwestern University officials discovered a suspicious package bearing the return address of a mathematics professor at the university. When campus police officers attempted to open the package, it detonated. One year later, Northwestern University received a second bomb package, which injured graduate student John Harris.
Over the next 17 years, sophisticated bombs disguised as packages and sent through the mail began to pop up all over the country, primarily targeting universities and airlines. In total, 16 bombs were sent, resulting in three deaths and dozens of injuries. Authorities quickly realized the man behind the crimes wasn’t a typical criminal, given the sophistication of his bombs and his planting of false clues to mislead investigators. The FBI, uncertain of his identity, used the case identifier UNABOM (University and Airline Bombing), leading the media to dub the terrorist the Unabomber.
As his crimes continued, the Unabomber grew bolder and began writing letters about his crimes and ideology to media outlets. In 1995, he sent a 35,000-word manifesto to The New York Times and The Washington Post, which described the anti-technology, Luddite stance behind his terrorism. The manifesto proved to be his undoing, as the wording and geographical information caught the attention of several people, including David Kaczynski. David had come to suspect his brother, Ted Kaczynski, of being the Unabomber and reported him to the FBI. On April 3, 1996, the FBI arrested Ted Kacyzinski at his remote cabin in Montana, where he lived as a recluse without electricity or running water. Kacyzinski ultimately pleaded guilty to his crimes, receiving two life sentences and marking the end of a nearly two-decade campaign of terror.
Was Ted Kaczynski an Experiment Subject?
Netflix’s Unabomber touches on the terror and epic manhunt of the case. However, it also goes back a little further to a time when Kaczynski wasn’t yet synonymous with the Unabomber or associated with the unkempt recluse living off survival skills in Montana. Much of the film follows his years at Harvard. Kaczynski entered Harvard at age 16 to study mathematics on a scholarship. At the time, he was one of Harvard’s most brilliant and promising students.
Unabomber doesn’t just touch on his genius, but also on a darker chapter of his life while at Harvard. During his second year at the school, Kaczynski became the subject of an abusive psychological experiment led by psychology professor Henry Murray. He volunteered for the experiment, believing he would be debating other students about the philosophical and personal beliefs they outlined in essays. Instead, Murray used the essays to brutally mock and demean the volunteers, subjecting them to high emotional distress in interrogation-like settings.
Kaczynski was one of the youngest and most vulnerable test subjects, spending roughly 200 hours as part of the experiment. Whether these experiments contributed to his life course remains unclear and controversial. After all, Kaczynski vehemently opposed using the insanity plea and was determined to illustrate that he was of sound mind during his crimes and that they were solely motivated by his anti-technology beliefs. However, Unabomber’s inclusion of the experiment is part of the film’s attempt to understand Kaczynski’s mind and how these formative years at Harvard shaped him. It raises interesting ideas about the vulnerability of brilliant young minds and the need for protection.
