Henry

Doctor Henry is an American physician and former Enclave scientist living in Shady Sands in Fallout 2 and in Jacobstown in Fallout: New Vegas.

Background
Dr. Henry could be considered one of the best scientists the wasteland has ever seen. Compared to Diogenes the Cynic by his contemporaries, Henry was motivated more by the problem itself, not its practical impact. Arcade Gannon expresses, "I'm not sure what [Dr. Henry] was after. Knowledge is power, but to what end for Henry, I have no idea ... He simply solved riddles because they existed."

New California
Dr. Henry used to work with the Enclave cyber-genetic research program at Control station Enclave and at various other Enclave installations. He claims he left because he felt his "work wasn't being appreciated," which is true: his theories on correcting the mutation in the Wasteland population were not popular with the rest of the Enclave scientists, most notably one of his colleagues, Dr. Schreber, who he worked with jointly on many genetic research projects in the past. Dr. Henry was arguing with Schreber at the Navarro base about the mutation problem for the five billionth time when Schreber, in a fit of anger, told Henry he was going to recommend that Henry be transferred to another Enclave facility where he would be put to work on cybernetic maintenance (the equivalent of cybernetic janitorial duty). Henry took the threat very seriously, and within hours, he stole a cybernetic dog (cyberdog) and slipped away from the Navarro facility, heading east and eventually making his way to NCR. The Enclave, while not pleased with his attitude and the directions of his research, were not happy with his escape (they need all the scientists they can get), and several soldiers were punished for negligence. Schreber never confessed to his role in Henry's disappearance, and simply claimed that Dr Henry had been acting suspicious for some time, and was displaying "sympathies for the mainland mutants."

After deserting the Enclave base at Navarro, Henry successfully integrated into the New California Republic and set up a clinic in Shady Sands. This clinic, in which he is perpetually busy, can be found directly to the south of Duppo's shop, unmarked. His field of expertise is cyber-genetics, which he is attempting to translate into an experimental treatment or cure for FEV mutations. The local crime lord, Merk, took an interest in his research, trying to hire the Chosen One to obtain his research papers. He successfully obscured his association with the Enclave in general, though drinking went a long way towards exposing his former associations.

At some point after the destruction of Control station Enclave, Dr. Henry was assaulted (allegedly by the Chosen One) and left in a critical condition. After recovering, he discovered that the Chosen One had left the more advanced cyberdog, K-9, in the care of Dorothy, in order for it to receive repairs. Henry, fearing that too much information about the Enclave could be obtained from K-9, attempted to destroy it, but he was stopped by Dorothy and the other cyberdog. The NCR government used his unsuccessful attempt as an excuse to seize both cybernetic canines, to obtain information about the Enclave and dog cyborgization. The resulting analysis killed both dogs.

Mojave Wasteland
Some time after the NCR captured Navarro, he met his old squadmates, Daisy Whitman, and young Arcade Gannon along with his mother. After the NCR began hunting Enclave personnel who were attempting to integrate themselves into the NCR, they left for the Mojave Wasteland. He met a stunning woman named Gibson, with whom he spent some time.

Eventually, he made it to Jacobstown. In Fallout: New Vegas 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 Rex.

Quests

 * Test mutagenic serum on a super-mutant. Try Broken Hills.: Asking Henry about cyber-genetics gives a mission to inject a super mutant with a prototype serum.

Quests

 * Guess Who I Saw Today: Henry will ask the player to go up to Charleston cave and retrieve a Stealth Boy. Following that, he will ask you bring Lily Bowen into his office so he can run a couple of tests on her.
 * For Auld Lang Syne: Dr. Henry is one of the Enclave remnants the player is tasked to find.
 * Nothin' But a Hound Dog: Dr. Henry is the only one in the Mojave Wasteland that is skilled enough to transplant a new brain into Rex.

Effects of player actions

 * After For Auld Lang Syne is completed, he and the squad will assist you at the Second Battle of Hoover Dam.

Behind the scenes

 * The player cannot heal themselves at Henry's clinic in Shady Sands.
 * Oddly, as discovered in dialogue, Henry knew about the Vault Behavioral Project.
 * Unlike all others with the title of Doctor in Fallout 2, he cannot heal the Chosen One.
 * If you start Nothin' but a Hound Dog after you completed For Auld Lang Syne, he will spawn back at Jacobstown while he should be in the bunker with his old squad.
 * Henry casually mentions his former affiliation with the Enclave, without concern for potential consequences, apparently trusting his safety to the well-armed population of Jacobstown.

Bugs

 * If Calamity is dead, he will still hand over control of the lab to her.
 * There may be two Henry(s) in the Second Battle of Hoover Dam, one with wasteland doctor fatigues, and one with an Enclave scientist outfit.
 * Sometimes he may just say, "Keep your head down - there could be snipers around". This makes any communication with him impossible. There is no known fix for this bug, however it may work to disable, enable, kill and resurrect him using console commands.
 * He may still be at Jacobstown even though you already finished For Auld Lang Syne.
 * Sometimes he will not perform medical services for the player.
