Tattinger was a 23rd century Starfleet officer who held the rank of commander and was assigned to Starbase 9 in the 2260s. In 2267, the USS Enterprise was on course for Starbase 9 after leaving Triskelion. James T. Kirk was looking forward to Tattinger's steak au poivre, which Commander Tattinger was famous for making. (TNG novelization: Relics) Tattinger presumably commanded Starbase 9.
