One of the most famous characters from the original Star Trek television series is the half-Vulcan Mr. Spock, played by Leonard Nimoy. Spock has a first name which is never stated in the series, as it is unpronounceable by humans.

Spock was the son of the Vulcan ambassador Sarek and his human wife Amanda. Although Spock identified himself as Vulcan, he had an ongoing internal conflict between the reason and logic of his Vulcan half and the emotion and intuition of his human half. By human standards, however, he was incredibly logical and utterly unflappable in the face of danger.

Nearly Spock's entire Starfleet career -- he was the first Vulcan to join Starfleet, much against his father's wishes -- was spent serving onboard a single ship, that being the famous USS Enterprise. Spock was originally assigned to the Enterprise as a Starfleet Cadet, participating in a training cruise. After his graduation from Starfleet Academy, and commission as an Ensign, he served for nearly eleven years under Captain Christopher Pike. During his time under Captain Pike, Spock advanced in grade from Ensign to Lieutenant Junior Grade and then to Lieutenant. Spock's first temporary command was as a Lieutenant where he ordered the evacuation of the Enterprise from Talos IV, after all of the senior officers had been kidnapped by the hostile inhabitants.

In the late 2260s, Spock was promoted to Lieutenant Commander and assigned as the Executive Officer and Science Officer of the Enterprise under Captain James T. Kirk (Star Trek: The Original Series). By 2268, Spock had risen in rank to a full Commander. He resigned his commission in 2270 to return to Vulcan.

In 2271 Spock returned to active duty and was reinstated as a Commander and posted as Science Officer to the USS Enterprise. Following the V'Ger crisis (Star Trek: The Motion Picture), and the loss of Enterprise Executive Officer, Commander William Decker, Spock assumed the post of First Officer and Science Officer of the USS Enterprise and embarked on its second five year tour of exploration.

In 2276, the Enterprise was retired from active service and refitted as a training vessel at Starfleet Academy. Spock was promoted to Captain and assigned as the Commanding Officer of the USS Enterprise. In 2282, he was temporarily relieved of command during the Genesis Crisis (Star Trek II: The Wrath of Khan), where Admiral James Kirk took command of the Enterprise to combat Khan Noonian Singh. During that same mission, Spock was killed in action after entering an anti-matter chamber with no protection, thus allowing warp engines to be brought online just in time to allow the Enterprise to escape the brilliant explosion that would create the planet Genesis.

It was later discovered that Spock had transferred his mind to the brain of a shipmate, Dr. Leonard McCoy, at death. In an honorary space burial Spock's body was enclosed in a torpedo and fired onto the rapidly forming Genesis planet. Thanks to the unique environment of the planet (the work of the Genesis Project) his body was actually "re-birthed" on the planet and it is rediscovered and his mind returned to it in Star Trek III: The Search for Spock.

Following Spock's rebirth, he completed an accelerated training program and was reinstated as a Captain in Starfleet. In 2286, after the "Whale Song Incident", he was assigned as the Executive Officer of the USS Enterprise (NCC-1701-A) (Star Trek IV: The Voyage Home). Spock remained as the Enterprise Executive Officer for for the next twelve years. During this time, he participated in a historic journey to the center of the galaxy (Star Trek V: The Final Frontier) and also was a key figure in forming the lasting alliance with the Klingon Empire (Star Trek VI: The Undiscovered Country).

In 2295, Spock retired completely from Starfleet service and entered the Federation Diplomatic Corps. In the early 2370s, Spock was seen outside his then-role as Federation ambassador on the Romulan homeworld of Romulus. He was attempting to bring about a peace between the Romulans and Vulcans, healing a rift between the two peoples thousands of years old. (Star Trek: The Next Generation (Unification Parts I and II) (Vulcans and Romulans are the same species; Romulans left the planet Vulcan after refusing to accept Surak's logical philosophy.) Spock's whereabouts after this event are unknown. It's possible that his work may have been responsible for the improving relations between the Federation and Romulans. (Star Trek Nemesis)

Spock had an older half-brother, Sybok, who eschewed pure logic, resembling the relationship between Data and Lore. He may also have been married, as Captain Jean Luc Picard once observed that he had met Sarek at "his son's wedding".

In the Star Trek novel Yesterday's Son, Spock is revealed to have fathered a son while trapped in the past on the now destroyed planet Sarpeidon. Using the Guardian of Forever , Spock travels back in time to rescue his son, called Zar; however Zar returns to the past after helping Spock defeat a Romulan plot. In the sequel, Time for Yesterday, Zar returns to the present to help Spock repair the malfunctioning Guardian of Forever. Zar returns to the past at the end of the novel, but also reveals he is sterile, precluding any possibility of grandchildren for Spock.
