Captain Simon Kendrick Williams was a career Starfleet officer in the late 24th century. During the 2370s, he commanded the USS Silverlight science vessel.
An archaeohistorian, Williams spent thirty years as a science officer. Early in his career, he was stationed on Memory Alpha. In 2363, he was assigned as captain of the science vessel USS Sulaweyo, and spent much of the ship's seven-year mission charting the farther reaches of the Alpha Quadrant. (Star Trek: Pendragon)
