Early life and career[edit | edit source]

Leonard McCoy, the son of clergyman, David McCoy, was born in Atlanta, Georgia, USA, Earth in 2227. (TOS comic: "Who's Who in Star Trek"; ST reference: Star Trek Chronology)

Growing up, McCoy was fascinated with reading medical dictionaries, before reading more widely and concentrating on reading medical journals. At the age of 16, McCoy traveled across the continental United States to visit his favorite uncle, who was attached to Starfleet at that time. While there, he obtained more specialized publications that he wanted to read, and gained his first exposure of space medicine. After returning home, McCoy announced to his parents that he was going to study medicine. (TOS comic: "Who's Who in Star Trek")

Starfleet career[edit | edit source]

Early career[edit | edit source]

After completing his studies at the Atlanta Medical College at the age of 26 (2253), McCoy enrolled in a Starfleet recruitment/training program, where he studied under Doctor Chhay. (TOS comic: "Who's Who in Star Trek"; TOS - My Brother's Keeper novel: Constitution)

After graduating from the Starfleet Medical Academy, McCoy went on to serve on dozens of alien worlds, plus several starship assignments, including one posting where he served as assistant chief medical officer. (TOS - My Brother's Keeper novel: Constitution)

Amongst his first assignments in Starfleet, McCoy served aboard the USS Crockett and the USS Xerxes. During these assignments, McCoy had several planetfalls and developed a good idea of what a good liberty port was. (TOS - Star Trek II Short Stories short story: "Under Twin Moons")

In 2257, McCoy was assigned to the USS Constitution as a medical officer under the direction of Doctor Christina Velasquez. Also serving aboard the Constitution where his old friends, James T. Kirk and Gary Mitchell, who served as second officer and navigator respectively. During their service together, Kirk saw McCoy save numerous lives on Kratosian Prime, Bender's Planet and Pariel VII. (TOS - My Brother's Keeper novels: Constitution, Enterprise)

Starfleet Medical[edit | edit source]

After learning that his father was suffering from a rare disease, McCoy successfully requested a transfer to Earth so that he could be near his father. He was assigned to Starfleet Medical in San Francisco, under the direct command of surgeon general Harris Eggleton. His father was also moved into a local medical facility so that McCoy could keep a close eye on him. McCoy later developed a technique for establishing axonal pathways between grafted neural pathways and basal ganglia, which Medical continued to use. (TOS - My Brother's Keeper novel: Constitution)

McCoy slowly started to recover as he clung to his work at Starfleet Medical, deciding to remain in San Francisco rather than looking for a starship assignment. Shortly after, Eggleton assigned McCoy to participate in a medical relief mission to Capella IV. McCoy was optimistic about returning to space but this was soon dashed by the obstinacy of the Capellans as they refused to embrace Federation medical technology. Upon his return to Earth and meeting with Eggleton, they both agreed that McCoy should remain on Earth and assist in a number of projects, including the development of a vaccine for choriomeningitis. (TOS - My Brother's Keeper novel: Constitution)

A few days later, over a dinner with Kirk, now commanding officer of the USS Enterprise, McCoy was offered the chief medical officer's position aboard the Enterprise after learning that Mark Piper was retiring from the service. After putting up a token argument, McCoy graciously accepted the request. (TOS - My Brother's Keeper novel: Enterprise)

Personal life[edit | edit source]

Family[edit | edit source]

David Andrew McCoy[edit | edit source]

As a child, Leonard was given a deep knowledge of the bible and was taught to respect all forms of life by his father, who worked as a clergyman. (TOS comic: "Who's Who in Star Trek")

David's health quickly deteriorated, although somehow he still clung unto life, but was in constant pain as he lay comatose in a biobed. Facing subjecting his father to a lingering death, McCoy switched off the life support system, ending his father's suffering. Unfortunately, McCoy was nearly shattered a few weeks later when a cure was found for his father's disease. (TOS - My Brother's Keeper novel: Constitution; TOS movie: Star Trek V: The Final Frontier)

Joanna McCoy[edit | edit source]

Following his divorce from Jocelyn, McCoy left Earth and spent many of Joanna's earliest years in space running away from all the pain and heartbreak of a life that had spiraled out of control. By the early 2260s, McCoy had re-established contact with his now-teenaged daughter and they were in regular contact. In late 2265, Joanna contacted her father to tell him that a skiing trip to Wyoming was going well, and a day later, learned that she had broke her leg after colliding with a tree. (TOS - My Brother's Keeper novels: Constitution, Enterprise)

Friendships[edit | edit source]

James T. Kirk[edit | edit source]

Following their service together aboard the Constitution, correspondence between the two became limited to a message every month or so, but never twice in the same month. McCoy was surprised in late 2265 when he received a message from Kirk just a few weeks after their prior conversation, but was saddened when the message was about the death of Gary Mitchell. (TOS - My Brother's Keeper novel: Constitution)

A few days later, McCoy met Kirk at Starfleet Headquarters following the Enterprise's return to Earth for Mitchell's funeral service. Deciding to walk into the Nob Hill district of San Francisco to get to Velluto's restaurant, McCoy gained the impression that Kirk wanted to talk to him but was afraid to, so he threatened to jump on a cable car unless Kirk started to talk. Sitting at the base of the Monument to the Fallen of Donatu V, Kirk told McCoy all of the details of the Enterprise's mission to the edge of the galaxy and of how Mitchell died. After their talk, the burden seemed to be eased and the two went on to Velluto's where they shared a bottle of Chateau Picard and toasted Mitchell's memory, he also convinced Kirk to visit Mitchell's parents and tell them how their son had died. It was during this meal, that Kirk offered McCoy the position of chief medical officer aboard the Enterprise, which, after some attempt by McCoy to put him off, he accepted. (TOS - My Brother's Keeper novel: Enterprise)

Gary Mitchell[edit | edit source]

Unlike many of Mitchell's friends, McCoy was one of the few to hit-it off with him almost immediately, although McCoy didn't become as close to Mitchell as Kirk was. In 2257, the three men were all assigned to the USS Constitution in various positions, and they often met in the ship's rec room to share some laughs and enjoy each other's company. However, McCoy and Mitchell were known to have the odd heated argument, especially on one occasion when McCoy accused Mitchell of being manipulative following his attempts to get Barton and Carvajal to switch duty shifts. (TOS - My Brother's Keeper novel: Enterprise)

Relationships[edit | edit source]

Nancy Pagano[edit | edit source]

McCoy first met Nancy Pagano during his time studying under Doctor Chhay at Starfleet Medical, where the two became close friends. A few years later in the mid-2250s, the two shared a brief romance, during which Pagano gave McCoy the nickname of "Plum". Shortly after the romance ended, Pagano married Professor Robert Crater and left with her husband to investigate the ruins on planet M-113. (TOS comic: "Who's Who in Star Trek"; TOS episode: "The Man Trap")

In 2266, the USS Enterprise, on which McCoy now served as chief medical officer, visited M-113 to perform annual medical checks on Professor Crater and Nancy. During this mission, McCoy was manipulated by a creature which had killed Nancy and had taken her appearance in order to acquire salt from the bodies of several Enterprise crewmen. McCoy eventually killed the creature with a phaser after it attempted to kill Captain Kirk. (TOS episode & novelization: The Man Trap)
