Matthew Brand Decker was a dedicated Starfleet officer who served during the 23rd century. Decker was one in a line of Deckers to serve in Starfleet, and his son, Willard Decker, by Matt's wife Jane, would become one-time commander of the USS Enterprise. (TOS episode: "The Doomsday Machine", TOS comic: "Who's Who in Star Trek, Issue 1", TOS movie: Star Trek: The Motion Picture.
During his days at Starfleet Academy and his early career, Decker was seen as insubordinate and not command material, although with high scores in athletic and academic classes. He dated many women, but eventually met Jane Hopkins and became a better student. (TOS comic: "Who's Who in Star Trek")
At one point while with the rank of lieutenant commander, Decker served aboard the USS Patton. In 2244, he commanded the Patton during the battle at Donatu V. He and Commander Jose Mendez of the USS Eisenhower were able to hold out against Klingon Captain Klaar's three ships until two Baton Rouge-class ships forced Klaar's force to withdraw. (ST reference: Federation: The First 150 Years)
By the early 2250s, Decker had risen to the rank of captain and assumed command of the USS Yorktown from Captain Christopher Pike, who went on to assume command of the Enterprise. After commanding the Yorktown for several years, Decker transferred to command the USS Constellation, where he would spend the rest of his career. Decker would eventually be promoted to the rank of commodore after having commanded three survey vessels. (TOS novel: Prime Directive, TOS comic: "Who's Who in Star Trek, Issue 1")
Decker once fought against Darok in a ground battle. Decker shot Darok in the leg, but treated it when the battle was over. Decker also signalled Darok's ship to tell them that Darok needed to be rescued. (DS9 novel: The Left Hand of Destiny, Book Two)
In 2263, while the Constellation was in the area of space known as the Taurus Reach, Decker's crew discovered what would become known to Starfleet as the Meta-genome. The Constellation was unable to investigate further due to other priorities from Starfleet Command, but Decker's report resulted in the fast-tracking of the construction of the Vanguard station in the Taurus Reach in order to secretly study the Meta-Genome. (VAN novel: Harbinger)
In 2266, Decker responded to a distress call from the Federation colony on Alpha Proxima II, along with Captain Kirk of the USS Enterprise. They found civil society on the verge of collapse, due to a plague caused by one of the Malkus Artifacts of the Zalkat Union. Decker and Kirk together resolved to impose martial law on the colony. (TOS - The Brave and the Bold, Book One novella: The First Artifact)
Decker was killed in the line of duty in 2267, in combat with the alien doomsday machine that the ancient Preservers designed to combat the Borg. (TOS episode: "The Doomsday Machine"; TNG novel: Vendetta)
