- "Hey, I'm just doing my job, and these pencil-necks ain't conductin' themselves in a way that'll make it go easy for 'em."
- ―Nicholas Ingraham[src]
Nicholas Ingraham worked as part of Ryan's Security detail, making him one of Sullivan's subordinates. Not much is known about him except for the fact that he was sent to the Air-Tite Archives in Minerva's Den to uncover incriminating evidence against certain "rebels" and "radicals" in Rapture by going through their personal records. He complained in an Audio Diary about the Archives' employees, such as Audrey Hesselgren, for being overly idealistic and making his work harder.
