Christof Schuster was a male Human of Austrian descent who served as a science officer in Starfleet in the mid 24th century. He was married, and in 2347 had a daughter, Elle.

As of 2354, Lieutenant Schuster was stationed at Starbase 32 with his daughter, while his wife served on another deep-space vessel. While there, he became friends with the base's assistant chief medical officer Beverly Crusher, and the two often shared childcare duties for both Elle and Crusher's young son, Wesley. That year, following the death of Lieutenant Commander Jack Crusher aboard the USS Stargazer, Schuster was offered the science officer's post on that ship. Schuster accepted, sending his daughter to live with cousins in Salzburg on Earth. (TNG novel: Losing the Peace)

In 2355, during the Battle of Maxia, Schuster manned the science station until the death of Lt. Vigo forced him to take over tactical. (TNG - The Lost Era novel: The Buried Age)

Author Christopher L. Bennett's annotations state that Schuster was named after Michael Schuster, who runs a Stargazer website.
