W.M. Jefferies

Captain George William Jefferies was a Starfleet engineer in the 22nd century. He was married in 2137. (Home is the Hunter)

He was in charge of the engineering team working on the NX Program in 2143; Charles Tucker was on his team. (ENT: "First Flight") He was still working on the Program when the NX-01 Enterprise was launched in 2151; he had occasion to argue with Captain Jonathan Archer over how heavily armed the NX-class should be. Archer was against increased armament, but after the Xindi crisis began to think Jefferies may have been right. (ENT: "Home")

He was the grandfather of Frederick William Jefferies, who went on to design the Jefferies tube. (Home is the Hunter) He was honored with a holoframe in the Tucker Memorial Building. (The Future Begins)
