Doctor Henry

Doctor Henry is a former Enclave scientist living in NCR in 2241 and in Jacobstown in 2281.

Core Region
After deserting the Enclave base at Navarro, Henry successfully integrated into the NCR and runs a clinic - in which the player cannot heal - in New California Republic. This clinic, in which he is perpetually busy, can be found directly to the south of Duppo's shop. It is unmarked. His field of expertise is cyber-genetics and he is attempting to translate this knowledge into an experimental treatment or cure for FEV mutations. The local crime lord, Merk, took an interest in his research and will hire the Chosen One to obtain his research papers.

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.

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 Rex.

Quests

 * Test mutagenic serum on a super-mutant. Try Broken Hills: The Chosen One must test the serum they are given on a super mutant in an attempt to cure them.
 * 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.

Other interactions

 * 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.
 * If the Chosen One has high enough science skills, you can offer to help him perform a field experiment with his serum.

Appearances
Dr. Henry appears in Fallout 2 and Fallout: New Vegas.

Bugs

 * Sometimes he will not perform medical services for the player.
 * 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.
 * There may be two Henry(s) in the Second Battle of Hoover Dam, one with Wasteland Doctor Fatigues, and one with a Enclave scientist outfit.
 * He may still be at Jacobstown even though you already finished For Auld Lang Syne.
