Mail bomb injures Yale professor

On June 24, 1993, Yale University computer science professor David Gelernter is seriously injured while opening his mail when a padded envelope explodes in his hands. The attack just came two days after a University of California geneticist was injured by a similar bomb and was the latest in a string of bombings since 1978 that authorities believed to be related.

In the aftermath of the attack on Gelernter, various federal departments established the UNABOM Task Force, which launched an intensive search for the so-called “Unabomber.” The bombings, along with 14 others since 1978 that killed 3 people and injured 23 others, were eventually linked to Theodore John Kaczynski, a former mathematician from Chicago. Kaczynski won a scholarship to study mathematics at Harvard University at age 16. After receiving his Ph.D. from the University of Michigan, he became a professor at the University of California at Berkeley. Although celebrated as a brilliant mathematician, he suffered from persistent social and emotional problems, and in 1969 abruptly ended his promising career. Disillusioned with the world around him, he tried to buy land in the Canadian wilderness but in 1971 settled for a 1.4-acre plot near his brother’s home in Montana.

For the next 25 years, Kaczynski lived as a hermit, occasionally working odd jobs and traveling but mostly living off his land. He developed a philosophy of radical environmentalism and militant opposition to modern technology, and tried to get academic essays on the subjects published. It was the rejection of one of his papers by two Chicago-area universities in 1978 that may have prompted him to manufacture and deliver his first mail bomb.

The package was addressed to the University of Illinois from Northwestern University, but was returned to Northwestern, where a security guard was seriously wounded while opening the suspicious package. In 1979, Kaczynski struck again at Northwestern, injuring a student at the Technological Institute. Later that year, his third bomb exploded on an American Airlines flight, causing injuries from smoke inhalation. In 1980, a bomb mailed to the home of Percy Wood, the president of United Airlines, injured Wood when he tried to open it. As Kaczynski seemed to be targeting universities and airlines, federal investigators began calling their suspect the Unabomber, an acronym of sorts for university, airline and bomber.

From 1981 to 1985, there were seven more bombs, four at universities, one at a professor’s home, one at the Boeing Company in Auburn, Washington and one at a computer store in Sacramento. Six people were injured, and in 1985 the owner of the computer store was killed–the Unabomber’s first murder. In 1987, a woman saw a man wearing aviator glasses and a hooded sweatshirt placing what turned out to be a bomb outside a computer store in Salt Lake City. The sketch of the suspect that emerged became the first representation of the Unabomber, and Kaczynski, fearing capture, halted his terrorist campaign for six years, until the bombings of June 1993. In 1994, another mail bomb killed an advertising executive at his home in New Jersey. In April 1995, a bomb killed the president of a timber-industry lobbying group.

This was to be the Unabomber’s final attack. With the help of Kaczynski’s older brother David, FBI agents gathered evidence against him and on April 3, 1996, arrested him in a remote Montana cabin. On May 4, 1998, Kaczynski was sentenced to four life terms in prison after pleading guilty in order to escape the death penalty.
