Doctor Henry

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

Background
Described as difficult to figure out but passionate about his research, Dr. Henry previously worked with the Enclave on canine cyber-genetics. His specialization was in both human and canine neuroscience. He also worked on the development of a mutagenic serum, aiming to cure super mutants as an alternative to the Enclave's initiative to kill the afflicted. The doctor and Enclave leadership did not see eye to eye, enough so that Henry chose to leave. He tells the Courier that leaving was the right decision, as the Enclave oil rig was destroyed shortly after his departure.

After leaving the Enclave, Dr. Henry integrated into the New California Republic, setting up a clinic in NCR town. Although some remnants of the Enclave will not speak about their past involvement with the group, one of the citizens of NCR town shares that they have heard about the Enclave from Henry, who spoke about it at length while drunk. His research gained the attention of Merk, the local crime lord, who sought assistance in stealing Henry's blueprints for building cybernetic canine guard units. As payment for assisting him with serum field work, Henry gives the Chosen One a cyberdog known as a Cyber-Hound Mk. II.

After moving on from NCR town, Dr. Henry spent time traveling with caravans, where he met with Gibson. He subsequently relocated to the Mojave Wasteland, joining other Enclave remnants fleeing death at the hands of the NCR and Brotherhood of Steel. He settled in Jacobstown, establishing his lab in the lodge. It is here that he researches the effects of prolonged Stealth Boy Mark II prototype usage by Nightkin, mentioning that his current lab is not as impressive as the facilities he had access to while in the Enclave. His primary objective is to cure the Nightkin's schizophrenia, but he is also capable of performing brain transplants for cyberdogs despite not having worked in the field recently.

Behind the scenes

 * According to the Fallout Bible, at some point after the destruction of Control station Enclave, Henry attempted to destroy a cyberdog named K-9 who was in Dorothy's care, fearing that too much information about the Enclave could be obtained from it.
 * The Fallout Bible also mentions that his theories on correcting mutations in the wasteland were not popular with other Enclave scientists, such as Dr. Schreber.

Bugs

 * Sometimes he will not perform medical services for the player character.
 * 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.
 * Starting Nothin' But a Hound Dog after completing For Auld Lang Syne instead of before will cause him to reappear in Jacobstown. This will also result in there being two Henry(s) in the Second Battle of Hoover Dam, one with wasteland doctor fatigues, and one with an Enclave scientist outfit.
