Early life


Kaczynski was born in Chicago and raised in Evergreen Park, Illinois.[3] Kaczynski was accepted to Harvard University at the age of 16.[3] He earned an undergraduate degree. He then earned a PhD in mathematics from the University of Michigan.[3] Kacyznski was a child prodigy who did well in mathematics.[4] He became an assistant professor at the University of California, Berkeley in 1967 at age 25.[3] He resigned two years later.[3]

The Unabomber


In 1971, he moved to a cabin without electricity or running water, in Lincoln, Montana. He lived there while learning survival skills. From 1978 to 1995, Kaczynski sent 16 bombs to targets including universities and airlines, killing three people and injuring 23.[5][6]

Kaczynski sent a letter to The New York Times on April 24, 1995.[3]

Kaczynski was arrested in his cabin on April 3, 1996. His brother, David, called the police so that they could arrest him.[7] He pleaded guilty of his crimes on January 22, 1998. He was an inmate of ADX Florence, Fremont County, Colorado. On December 14, 2021, he was moved from ADX Florence to the Federal Medical Center, Butner, North Carolina after being diagnosed with late-stage cancer.[8]

Written works


Kaczynski wrote many books, Industrial Society and Its Future, Anti-Tech Revolution: Why and How, and Technological Slavery are his most famous.[9] Industrial Society and Its Future was best known as the "Unabomber's Manifesto".[10][11]

At 12:23 a.m. on June 10, 2023, he was found in his cell unresponsive. He was taken to a hospital where he was pronounced dead.[12] Prison officials believe he committed suicide.[13]
