Doctor Henry

Doctor Henry is a scientist in NCR in 2241. He later lived in Jacobstown in 2281.

Background
Henry served under Captain Judah Kreger before he deserted alongside Orion Moreno and Cannibal Johnson. Some time before the destruction of the Enclave Oil Rig he deserted the Enclave because he and the leadership "didn't see eye to eye"; he took with him a cybernetic canine

Deserter
After Henry deserted he successfully integrated himself into the NCR and ran a clinic in the capital. His field of expertise was cyber-genetics and he attempted to translate his knowledge into an experimental treatment or cure for FEV mutations. If the Chosen One has high enough science skills, you can offer to help him perform a field experiment with his serum. However, when the serum was tested on a super mutant, it caused the subject to die a horrible death, but technically it still successfully 'treated' the mutation.

The local crime lord, Merk, took an interest in his research and will hire the Chosen One to Retrieve papers from Dr Henry.

Some time after the NCR captured Navarro he met his old squadmates, Daisy Whitman, and a young Arcade Gannon along with his mother. Together they left for the Mojave Wasteland after the NCR began hunting Enclave personnel who were trying to integrate themselves into the NCR.

Mojave Wasteland
Dr. Henry appears in Fallout: New Vegas at Jacobstown, where he is attempting to find a cure to the nightkins' schizophrenia, brought on by prolonged Stealth Boy use. Should the Courier decide to assist in his research with nightstalkers and the Stealth Boy Mark II, he finds the cure for the nightkin. Dr. Henry is also a part of the quest Nothin' but a Hound Dog where he performs surgery to replace the brain of cyberdog Rex.

During the quest For Auld Lang Syne, you re-unite him with his old squad at the Remnant's Bunker, once the quest is complete he and the squad will assist you at the second battle for Hoover Dam.

Sometimes however, two Doctor Henry's will arrive. With one in Enclave scientist uniform and one in Doctor Henry's normal clothes.
