Ted Kaczynski (A.K.A. The Unabomber) – Ted Kaczynski is hard to top. Labeled not merely a serial killer, but a ‘domestic terrorist’ by the FBI, Kaczynski skipped the 5th grade after testing 167 on an IQ test. He entered Harvard at the age of 16 where he earned his undergraduate degree by age 20. He earned his PhD in mathematics at the University of Michigan, where he focused on geometric function theory. After this, he was hired by the University of Berkeley, becoming their youngest professor. He won the University of Michigan’s Sumner B. Myers prize, thanks to a Ph.D. thesis on boundary functions, recognized as that year’s best mathematics dissertation.
Ted Kaczynski resigned not long after being hired. He saved up money by working odd jobs until he could afford to purchase a small piece of land, during which time he taught himself various survival skills in order to become self-sufficient. Unfortunately, the land around him was being continually destroyed by industrial development. Ted Kaczynski’s beliefs became progressively radicalized through the study of political philosophy, and he eventually decided that the only way to stop the progressive destruction of the environment was through violence.
He eluded capture for decades, killing 3 people and injuring 23.
