Henry Doctor Henry is a former Enclave scientist living in NCR in 2241 and in Jacobstown in 2281 . Background . New California . Doctor Henry was a pudgy guy with a shiny bald head and thick - lensed glasses . He used to work with the Enclave cyber - genetic research program at the Poseidon oil rig and at various other Enclave installations . In NCR , Dr . Henry 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 , Dr . Henry 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 NCR and runs a clinic in New California Republic . This clinic , in which he is perpetually busy , can be found directly to the south of Duppo ' s shop , but it is unmarked . His reason for this departure is unclear , but he hints that it was due to his " single - minded colleagues " only striving for purification . 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 . K - 9 was left in NCR by the Chosen One so that he could receive necessary repairs from Dorothy and , not long after his recovery , Dr . Henry ( who had been placed in critical condition after being reportedly assaulted by the Chosen One some time earlier ) . Dr . Henry , afraid that too much information about the Enclave would be obtained from K - 9 , attempted to destroy the cyborg , but was stopped by cyberdog and Dorothy , who suspected what Dr . Henry was planning . The NCR government used the attack as an excuse to confiscate K - 9 and cyberdog in order to learn more information about the Enclave as well as what makes the two of them " tick . " At last report ( and over Dorothy ' s objections ) , K - 9 and cyberdog were disassembled and analyzed . Structural damage during the disassembling is reported to have killed them both . Sometime 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 " " at Jacobstown , where he is attempting to find a cure to the nightkin s ' schizophrenia , brought on by prolonged Stealth Boy use . Should the Courier decide to assist in his research with night stalker s and the 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 . Appearances . Dr . Henry appears in " Fallout 2 " and " " .
