Too many people have opinions on things they know nothing about. And the more ignorant they are, the more opinions they have.

Thomas Hildern is the Director of Operations of the Office of Science and Industry (OSI) East, living in the Camp McCarran in 2281. He is a colleague of Angela Williams.


Director of the Eastern division, Hildern controls the Dam's power from Camp McCarran. If you are in front of the two vending machines you missed the OSI lab on the right that leads to the office of Hildern. He only cares for his research which also includes trying to prevent a shortage of food in the NCR. He is constantly outmatched by Keely (who he has a very low opinion of), and often takes credit for the work of his assistants (putting his actual competence for his position into question). He was trained by the Followers of the Apocalypse and left to help found the OSI. He believes in advancing himself through his research and eventually hopes to get to OSI Central.

Dr. Hildern can be found in his office located inside the Camp McCarran terminal building in the southeastern area on the ground floor of the terminal. Enter through the leftmost entrance of the terminal building.
