Brother of Ted Kaczynski who identified his writing and turned him in to the FBI
Profile
David Kaczynski was born on October 3, 1949, in Chicago, Illinois, the younger brother of Theodore "Ted" Kaczynski. Growing up, David idolized his older brother, who was seven years his senior and a brilliant student. The two shared an interest in nature and the outdoors, though Ted grew increasingly withdrawn over the years, sending hostile and resentful letters to their parents from his isolated cabin in Montana [1].
In 1995, after The Washington Post published the Unabomber's 35,000-word manifesto, David's wife Linda Patrik noticed striking similarities between the text and Ted's earlier writings and speech patterns. David initially resisted the idea, insisting his brother had never been violent. But after reading the manifesto himself at a library, he recognized Ted's distinctive voice and argumentative style [2]
What followed was an agonizing moral crisis. As David later described it: "If I did nothing, some other person would be blown up or maimed. On the other hand, I'd either have some innocent person's blood on my hands if I did nothing, or my brother's blood on my hands if I stepped forward" [3]. He contacted the FBI through an attorney, securing a promise of confidentiality and advance notice of any arrest. That promise was broken — David learned of Ted's capture from a television broadcast [2].
Federal prosecutors sought the death penalty despite having allegedly promised psychiatric help. David hired lawyers who ultimately helped secure a life sentence instead. The experience transformed him into a passionate anti-death penalty advocate. He became executive director of New Yorkers Against the Death Penalty and has traveled the country alongside Gary Wright, a Unabomber bombing survivor, speaking about reconciliation, mercy, and the failures of capital punishment [3]. David donated the $1 million FBI reward to a fund assisting Unabomber victims [4].
