relationship, the brothers remained close into adulthood and exchanged
copious correspondence.

Ted Kaczynski in the family's Iowa apartment in the late 1960s, in his
mid-20s. By this time, he was a professor at the University of California,
Berkeley. Shortly thereafter, he began to withdraw from society and
wander. Given the ethos of the time, brother Dave said, Ted's "dropping
out seemed like almost a heroic thing."

Ted Kaczynski as an assistant professor of mathematics at the University
of California, Berkeley, in the late 1960s. At Berkeley he was
excruciatingly shy, to the point that his students scorned him. Ted
eventually shunned mathematics and technology. He later move to Montana
and would bomb this campus twice.

Ted Kaczynski over a car near Lincoln, Mont., in the early 1970s, after
Ted had settled outside the small town, immersing himself in a
self-imposed survivalist retreat. He shunned electricity, poached wild
game and grew his own vegetables.

But Ted's Montana retreat only seemed to fuel his rage and isolation. He
railed against overhead jets interrupting his sleep, his perfect quiet. He
began trashing nearby cabins, booby-trapping trails with neck wires meant
to decapitate anyone speeding by on a noisy motorcycle or snowmobile. He
also started building bombs--primitive devices, with triggers fashioned
from match heads.

early 1970s.

Ted's journal entries from this period show he was no environmentalist,
even though the public would later perceive the Unabomber as an
eco-crusading Luddite. "I don't even believe in the cult of
nature-worshipers or wilderness-worshipers. (I am perfectly ready to
litter in parts of the woods that are of no use to me...)," he wrote.

prepared as evidence against him in federal court.

Ted Kaczynski outside his parents' home in west suburban Lombard in 1978,
the year he delivered his first bomb. The bomb never made it to its
designated addressee, an engineering professor in Troy, N.Y., instead
detonating when it was opened by a Northwestern University police officer.
The bomb was weak, injuring the officer's hand.

In a journal entry from 1977, Kaczynski laid out his plans to kill. "I
emphasize that my motivation is personal revenge. I don't pretend to any
kind of philosophical or moralistic justification. ... My ambition is to
kill a scientist, big businessman, government official or the like. I
would also like to kill a Communist."

Ted Kaczynski and his mother, Wanda, in Lombard in 1978, the year Ted
delivered his first bomb. After Dave fired Ted from his factory job for
harassing a female supervisor, Dave resigned and traveled to a remote part
of Texas that would become his sanctuary. The brothers later would
reconcile.

partly, he later wrote, to blend into the population so he could more
easily carry out a bombing.

Ted Kaczynski in Lombard, 1978. That summer he started working at a
foam-cutting factory where his father and brother also worked. Brother
Dave, a part-time supervisor at the factory, was forced to fire Ted after
he posted insulting limericks about a woman he dated--a female
supervisor--around the factory.

During his stay in Lincoln, Mont., in the early 1970s, Ted Kaczynski
shunned electricity, poached wild game and grew his own vegetables. But
the Montana retreat only seemed to fuel his isolation and bizarre
behavior.

Ted Kaczynski in Montana in 1981. By this time he had sent several bombs,
including one that created smoke but did not detonate aboard an airliner
in 1979. The FBI got involved and later coined the code name UNABOM or
Unabomber to refer to the man they would not catch until 1996, with the
help of his brother.
