In a Sacramento, California, courtroom, Theodore J. Kaczynski pleads guilty to all federal charges against him, acknowledging his responsibility for a 17-year campaign of package bombings attributed to the “Unabomber.”

Born in 1942, Kaczynski attended Harvard University and received a PhD in mathematics from the University of Michigan. He worked as an assistant mathematics professor at the University of California at Berkeley, but abruptly quit in 1969. In the early 1970s, Kaczynski began living as a recluse in western Montana, in a 10-by-12 foot cabin without heat, electricity or running water. From this isolated location, he began the bombing campaign that would kill three people and injure more than 20 others.
