Commander Williams was a 22nd century Starfleet officer who worked in a support capacity to Admiral Maxwell Forrest in overseeing the mission of Enterprise NX-01.
At Starfleet Medical in 2151, Williams was part of a group of Starfleet officers who conferred with Vulcan Ambassador Soval regarding the disposition of Klaang, a Klingon courier who had recently crash landed on Earth. Along with Jonathan Archer, Williams objected to the Vulcans attempting to subvert the decision-making process from Starfleet. (ENT: "Broken Bow")
