Ensign Williams was a Starfleet officer serving aboard the USS Enterprise-D in 2366.

Ensign Williams was in the same art class as Captain Jean-Luc Picard and Lieutenant Wright and, shortly before the Enterprise-D arrived at Tanuga IV, painted a picture that was inspired by geometric constructivism. According to Data, Williams' "striking style was heavily influenced by geometric constructivism." (TNG: "A Matter of Perspective")
