Harvard graduate Ted Kaczynski - better known by his FBI codename, the Unabomber - has submitted an entry to a directory for his class reunion.
The Harvard Alumni Association has apologised for publishing the note from Kaczynski, who graduated in 1962.
In the directory, he lists his profession as "prisoner" and his awards as "eight life sentences".
He was convicted in 1998 of killing three people and injuring 23 in an almost two-decade mail-bombing spree.
Kaczynski, who lived as a recluse in Montana, was caught in 1996 when his brother recognised his idiosyncratic writings and tipped off authorities.
He was unable to join his former Harvard classmates for this week's 50-year reunion in Cambridge, Massachusetts, because he is serving a life sentence in a maximum security prison in Colorado.
A Harvard spokesman said the update had been submitted by Kaczynski, now 70.
In a statement, the Harvard Alumni Association said: "While all members of the class who submit entries are included, we regret publishing Kaczynski's references to his convictions and apologize for any distress that it may have caused others."
The former child prodigy studied mathematics at Harvard and received master's and doctoral degrees from the University of Michigan.
