evidence: David Kaczynski wanted his role kept confidential, but his identity quickly leaked out and Ted Kaczynski vowed never to forgive his younger sibling. He ignored his letters, turned his back on him at court hearings and described David Kaczynski in a 1999 book draft as a "Judas Iscariot (who) … doesn’t even have enough courage to go hang himself." Ted Kaczynski was born May 22, 1942, in Chicago, the son of second-generation Polish Catholics — a sausage-maker and a homemaker. He played the trombone in the school band, collected coins and skipped the sixth and 11th grades. His high school classmates thought him odd, particularly after he showed a school wrestler how to make a mini-bomb that detonated during chemistry class. Harvard classmates recalled him as a lonely, thin boy with poor personal hygiene and a room that smelled of spoiled milk, rotting food and foot powder. After graduate studies at the University of Michigan at Ann Arbor, he got a job teaching math at the University of California at Berkeley but found the work difficult and quit abruptly.
