Duvall

Captain Duvall was a Starfleet officer during the mid-22nd century. 

In 2144, Duvall was a pilot in the NX test program and the first Human to break warp 3 in the NX-Delta prototype - after first choices A.G. Robinson and Jonathan Archer had some trouble with authority after making an unauthorized test flight to avoid the closing of the program. 

In 2151, Duvall was given the command of the Earth starship Shenandoah. Upon learning this, Enterprise Captain Jonathan Archer was surprised, commenting, "thank God we're a hundred light years away." (ENT: "Silent Enemy")
