Stocker

From Memory Alpha, the free Star Trek reference.

Commodore Stocker was a 23rd century Starfleet flag officer who served his entire career working behind the desk.

In 2267, Stocker was the newly assigned commander of the Federation Starbase 10, to which he was transported aboard the USS Enterprise.

En route to the starbase, the Enterprise stopped at Gamma Hydra IV where Captain James T. Kirk and the other senior officers were infected with a radiation disease that caused premature aging. This forced Stocker to assume command of the Enterprise

While in command, Stocker violated the Romulan Neutral Zone, as he attempted to take a shorter route to Starbase 10. While in the Neutral Zone, the Enterprise was attacked by several Romulan Birds-of-Prey. Being an inexperienced officer in battlefield conditions, Stocker panicked and almost lost the Enterprise before the cured Kirk could retake command and save the ship. (TOS: "The Deadly Years")

Soon afterward, Commodore Stocker assumed command of Starbase 10. (VOY: "Tinker Tenor Doctor Spy")

Stocker was played by actor Charles Drake.
