Who Was Ted Kaczynski?
Theodore John Kaczynski, better known as the Unabomber, was an American mathematician and convicted domestic terrorist. From 1978 to 1995, he carried out a bombing campaign across the United States. His attacks killed three people and injured 23 others.
Kaczynski was a gifted math student. He studied at Harvard University and later earned a master’s degree and a Ph.D. in mathematics from the University of Michigan. He also worked as an assistant professor of mathematics at the University of California, Berkeley.
He later left his academic career and moved to a small cabin near Lincoln, Montana. He lived a simple and private life there while planning and carrying out his attacks.

Career at UC Berkeley
After earning his Ph.D., Kaczynski became an assistant professor of mathematics at the University of California, Berkeley. He started teaching in 1967.
During his short time at Berkeley, he published several mathematics papers. However, he resigned from the university in 1969.
In 1971, Kaczynski and his brother David bought land near Lincoln, Montana. Kaczynski later moved there and lived in a small cabin without normal modern comforts. The FBI later found important evidence in that cabin.
The Unabomber Bombing Campaign
Kaczynski began his bombing campaign in 1978. His first known bomb was found at the University of Illinois in Chicago. The device exploded and injured a person.
Over the next 17 years, he mailed or placed 16 bombs. His targets included university staff, scientists, business people and others connected to airlines or technology.
The attacks killed three people and injured 23 others. The FBI created the UNABOM task force to investigate the case. The name came from “University and Airline Bombing.” More than 150 investigators and other staff eventually worked on the case.
One of the victims was Hugh Scrutton, who was killed in 1985. In 1994, advertising executive Thomas Mosser was killed. In 1995, Gilbert Murray, president of the California Forestry Association, was also killed.
The Unabomber Manifesto
In 1995, Kaczynski sent a long essay called “Industrial Society and Its Future” to major newspapers. The essay was about modern technology and society.
The 35,000-word manifesto was published in September 1995. The FBI hoped that someone might recognize the writer’s ideas or writing style.
Kaczynski’s brother, David Kaczynski, recognized similarities between the manifesto and writings from his brother. David gave the FBI documents written by Ted.
FBI investigators compared the writings and concluded that the same person had likely written them. This became a major break in the case.
Arrest and Trial
On April 3, 1996, FBI agents arrested Kaczynski at his cabin near Lincoln, Montana.
Investigators found bomb parts, thousands of handwritten pages and other evidence inside the cabin. They also found a live bomb that was ready to be mailed.
Kaczynski later pleaded guilty in January 1998. He received life imprisonment without the possibility of parole. He avoided a death sentence as part of the agreement.
Personal Life and Family
Kaczynski never married and had no children.
His brother David played an important role in the case. David struggled with the decision to report his brother to the FBI, but his information helped investigators identify Kaczynski.
Kaczynski spent much of his adult life away from normal society. His cabin in Montana became closely linked to the investigation and his criminal activities.
Death in 2023
Kaczynski died on June 10, 2023, at the age of 81. He was being held at the Federal Medical Center in Butner, North Carolina.
Reports said that Kaczynski died by suicide while in prison. He had also been suffering from late-stage cancer.
His death ended the life of a man whose 17-year bombing campaign became one of the most widely known criminal investigations in U.S. history.
