Theodore John Kaczynski (/kəˈzɪnski/; born May 22, 1942), also known as the Unabomber, was an American mathematician and anarchist who moved to a remote cabin to live as a recluse, having concluded that industrial revolution is root cause of collapse of society.
Kaczynski was born and raised in Evergreen Park, Illinois. While growing up in Evergreen Park he was a child prodigy, excelling academically from an early age. Kaczynski was accepted into Harvard University at the age of 16, where he earned an undergraduate degree. He subsequently earned a PhD in mathematics from the University of Michigan. He became an assistant professor at the University of California, Berkeley in 1967 at age 25. He resigned two years later.
In 1971, he moved to a remote cabin without electricity or running water, in Lincoln, Montana, where he lived as a recluse while learning survival skills in an attempt to become self-sufficient.
He was a mathematics prodigy, but abandoned his academic career in 1969 to pursue a more primitive life. Between 1978 and 1995, Kaczynski killed three people and injured 23 others in a nationwide mail bombing campaign against people he believed to be advancing modern technology and the destruction of the environment. He authored Industrial Society and Its Future, a 35,000-word manifesto and social critique opposing industrialization, rejecting leftism, and advocating for a nature-centered form of anarchism.
