I like this little tidbit of information:
Connell (Killian's widow) said Killian did not type, and though he did take notes, they were usually on scraps of paper. "He was a person who did not take copious notes," she said. "He carried everything in his mind."
'Connell (Killian's widow) said Killian did not type"
According to CBS News, he not only knew how to type but also could perfectly center proportional font.
