Theodore John Kaczynski was born in Chicago on May 22, 1942, to working-class parents Wanda Theresa (née Dombek) and Theodore Richard Kaczynski, a sausage maker.[12] The two were Polish Americans who were raised as Roman Catholics but later became atheists.[13]
What an odd thing to include.
Edit: Here's another oddity:
Kaczynski used a typewriter to write his manuscript, capitalizing entire words for emphasis, in lieu of italics.
Typerwriters didn't have italics and it wouldn't be only a crazy person writing on a typewriter in 1995.
