Chief Petty Officer Miles Edward O'Brien, played by Colm Meaney, is a character in Star Trek: The Next Generation and Star Trek: Deep Space Nine. O'Brien was originally the transporter chief of the USS Enterprise-D. He was later promoted to Chief of Operations of Deep Space Nine. O'Brien is the only major Star Trek character described as both ethnically Irish and born on Earth in Ireland.
According to Colm Meaney, at first O'Brien "was just there, not really established as a character, and that went on for a bit." He can be seen as the battle bridge's conn operator in the first TNG episode, "Encounter at Farpoint." Appearing on and off in more TNG episodes, it wasn't until the second season episode "Unnatural Selection" that Meaney's character was actually named, and the second episode of season 4, "Family," before the character was finally given a first name. However, Meaney came to like the arrangement of being hired on an episode-by-episode basis, and was hesitant to sign on as a regular on DS9. Along with Worf, Miles O'Brien is one of the two characters that moved from TNG to be a main character on DS9.
The backstory of the character states that Miles O'Brien was born in Killarney, a town in County Kerry in Ireland, Earth, in September 2328. He claims descent from Brian Boru, the famous Ard Rí, or High King of Ireland (and founder of the O'Brien Clan). His father, Michael O'Brien, wanted him to play the cello, so he pursued this and was eventually accepted into the Aldebaran Music Academy (revealed in DS9 episode "Shadowplay"). However, a few days before he was scheduled to start classes there, he enlisted in Starfleet. O'Brien can also be seen playing the cello as part of Data's string quartet early in the TNG episode "The Ensigns of Command". In the DS9 episode "Invasive Procedures", it is revealed he has two brothers.
