Before he was known as "The Unabomber," 25 year old Theodore John Kaczynski lived in a small backyard cottage at 2628A Regent Street in Berkeley, California, while teaching mathematics at the University of California, Berkeley. He lived at the residence for roughly two years starting in the summer of 1967 before abruptly resigning his position, giving no explanation to his colleagues, and leaving academia forever. Within a few years, he would move to a remote 10 by 14 foot cabin in Montana and begin the 17 year mail bombing campaign that killed three people, injured 23, and made him one of the most infamous domestic terrorists in American history.

Between 1978 and 1995, the United States was terrorized by bombs being mailed to mainly Universities and Airlines. Because of these targets, the FBI labeled the terrorist the "Unabomber." In all, 16 bombs were attributed to the Unabomber that killed 3 people and injured 23. On April 3, 1996, the FBI arrested Theodore John Kaczynski in a small cabin in Montana after his brother David recognized his writing style in his manifesto, "Industrial Society and Its Future," published by The Washington Post and The New York Times on September 19, 1995.
Ted Kaczynski was without a doubt brilliant before he turned to a life off the grid. He was born on May 22, 1942 in Chicago, Illinois and raised in the suburb of Evergreen Park, where his 165 IQ allowed him to graduate high school in just three years. At age 16, he enrolled at Harvard University on a scholarship and graduated four years later with a degree in Mathematics. He then earned a master's degree and a doctorate in mathematics from the University of Michigan by 1967, at age 25. His doctoral dissertation, "Boundary Functions," was later described by his doctoral advisor Allen Shields as of a quality that would only be understood by a handful of mathematicians in the world.

Immediately after receiving his Ph.D., Kaczynski was hired as an acting assistant professor of mathematics at the University of California, Berkeley for the 1967-1968 academic year, at age 25, making him the youngest assistant professor in the department. During his two years at Berkeley, he lived in a small back cottage located at 2628A Regent Street.
Colleagues would later describe Kaczynski as an unremarkable and "almost pathologically shy" professor who made no close friends in the department. His classroom performance was considered mixed, and student evaluations described him as a poor teacher.
On June 30, 1969, at the end of the 1968-1969 academic year, Ted suddenly quit his role at UC Berkeley without reason. He was 27 years old. Department chairman John Addison and professor Calvin Moore attempted to convince him to stay, with Addison later writing to Kaczynski's Michigan doctoral advisor that Kaczynski had "submitted his resignation quite out of the blue" and had said that "he was going to give up mathematics and wasn't sure what he was going to do." Kaczynski then moved back to his parents' home in Lombard, Illinois. In 1971, he and his brother David built a small hand crafted cabin near Lincoln, Montana. He would live there in near total isolation, without electricity or running water, for the next 25 years.
Kaczynski was arrested at the Montana cabin on April 3, 1996 after his brother David recognized his writing style in the Unabomber's manifesto and quietly reached out to the FBI. He was found with a fully assembled and ready to mail package bomb, roughly 40,000 pages of handwritten journals, drafts of the manifesto, and detailed diagrams of the bombs. He pleaded guilty on January 22, 1998 and was sentenced to eight consecutive life sentences without the possibility of parole. He spent most of his sentence at the U.S. Federal Supermax facility ADX Florence in Colorado before being transferred to a federal medical center in Butner, North Carolina in 2021 for treatment of late stage cancer. He died at the Butner facility on June 10, 2023 at age 81. His death was ruled a suicide.
The small home is located on the west side of Regent St, and is essentially behind a large, brown, craftsman style home located at 2626 Regent St. From the street you can see the gate with the address 2628 and see the top of the small, cream-colored home that on first glance appears to be a garage. The house is private property. Please remember to be respectful and do not attempt to talk to current residents or neighbors.
