While at Harvard, Kaczynski was taught by famed logicia Willard Van Orman Quine, scoring at the top of Quine's class with a 98.9% final grade.
He was also noted as the youngest professor ever hired by the university, but this position proved short-lived. Kaczynski received numerous complaints and low ratings from the undergraduates he taught.
The chairman of the mathematics department, J. W. Addison, called this a "sudden and unexpected" resignation, while vice chairman Calvin Moore said that given Kaczynski's "impressive" thesis and record of publications, "He could have advanced up the ranks and been a senior member of the faculty today.
In all, 16 bombs—which injured 23 people and killed three—were attributed to Kaczynski.
A court-appointed psychiatrist diagnosed Kaczynski as suffering from paranoid schizophrenia, but declared him competent to stand trial.
Kaczynski is serving a life sentence without the possibility of parole as Federal Bureau of Prisons register number 04475-046 in ADX Florence, the federal Administrative Maximum Facility supermax in Florence, Colorado."
