Henry Archer Henry Archer was the primary developer of the first warp engine capable of reaching warp five , and was one of the principal designers of . He was the father of Jonathan Archer and a good friend of Emory Erickson , the inventor of the transporter on Earth . ( ) Henry worked closely with Dr . Zefram Cochrane to develop the warp five engine at the Warp Five Complex in Bozeman , Montana as part of the NX Program . ( ) Prior to Cochrane ' s disappearance in 2119 , Henry took his son Jonathan on a tour of the Warp Five Complex , and introduced the boy to Cochrane , Tasaki , and other scientist s working at the facility . Jonathan later revealed he did not know the significance of his father ' s work at the time . ( ; ) In 2121 , Henry helped his son build and fly a remote - controlled starship model . During this time , the elder Archer admonished his son ' s disrespect for the Vulcan s , whom Jonathan believed were responsible for holding back Human ity ' s advancement into space . Although Henry insisted that Vulcan Ambassador Soval ( whom Jonathan referred to as " Ambassador Pointy " ) had been very helpful , he also expressed confusion and disappointment at the Vulcans ' refusal to share their technology , lamenting , " " They have their reasons . God knows what they are . " " Henry assisted Jonathan in flying his model starship on a , but the youth found keeping the craft in the air to be difficult . When the toy crashed , Henry advised his son that he " " can ' t be afraid of the wind . Learn to trust it . " " The younger Archer took this advice to heart thirty years later , when he made the decision to abandon his prejudices against Vulcans and start trusting Sub - Commander T ' Pol . ( ) On the day before he entered flight training , Jonathan asked his father what would happen if he failed . The elder Archer ' s response was , " " Don ' t fail . " " ( ) Henry spent the last two years of his life experiencing frequent pain and hallucinations , talking to people who weren ' t there , and often not even recognizing his son or wife due to advanced Clarke ' s Disease . He died in 2124 before his warp five engine could be constructed , since the Vulcans had held back the engine ' s development program . As a result , Jonathan Archer ' s resentment towards Vulcans grew into a grudge which held until the 2150s . ( ) In 2152 , a biography on the life of Henry Archer was in the works . Jonathan Archer was asked to write a one - page preface for his father ' s biography , a task he put off for weeks as he found it difficult to sum up his father ' s life in one page . He ultimately completed it with feedback from T ' Pol . One draft of the preface included the following : " " How does one measure a man ' s legacy ? Is it defined [ by ] the works he ' s created . . . the technological advances that will forever alter the course of Human history ? If so , then no man since Zefram Cochrane himself has made a more lasting contribution to the future of humankind than my father , Doctor Henry Archer . When I was about eight years old , my father took me on a tour of the Warp Five facility outside Bozeman , Montana . He introduced me to the people he worked with . . . scientists with names like Tasaki . . . and Cochrane . At the time , I didn ' t realize the significance of those names . . . or the significance of my father ' s work . " " ( ) Appendices . Background information . Henry Archer was played by actor Mark Moses in his second of two " Star Trek " appearances . The shirt Moses wore in the final scene of " Broken Bow " was sold off on the " It ' s A Wrap ! " sale and auction on eBay . As evidenced by the second draft of the script for ( dated ) as well as by the episode ' s shooting schedule , this character ' s first name was originally to have been " William " . The change from that to " Henry " was listed as one of six revisions of character names in a one - page " script note " at the start of the final draft script of ENT pilot ( the page was dated ) . The revised final draft script of " Broken Bow " ( dated 11 May 2001 ) simply described Henry Archer , when he appears in the teaser of that installment , as " " in his 40 ' s " [ . . . ] " wearing 22nd century civilian clothing . " " When he is thereafter shown with Zefram Cochrane , the script pointed out , " " [ He ] is only a few years younger than when we saw him in the opening scene . " " In the first draft script of ( dated , it was established that Henry Archer often took his son Jonathan on camping trips to Yosemite National Park . There appears to be some contradiction as to when Henry Archer died . " Cold Station 12 " stated that he passed away when Jonathan Archer was twelve years old , or roughly 2124 ; dialogue in " Daedalus " , however suggested that he was still alive when Jonathan entered flight school . Relating back to a reference stated in , it was established that Jonathan graduated from flight school when he was twenty - four years old , or roughly 2136 , suggesting Henry was still alive in the early 2130s . Inconsequently , the latter timeframe was supported by a scripted but ultimately omitted scene from an early draft of , where Jonathan was to have visited his father ' s grave on Earth . According to Henry ' s grave marker , he was born in 2077 and died in 2133 . ( ENT Season 4 Blu - ray special features ) Apocrypha . Henry Archer also appears in the novelization of " Broken Bow " .
