Over time the general practitioner has used many false names corresponding to "The health practitioner" (good, we all know that, it's in actual fact a name so far as we're concerned), "John Smith", "Sir healthcare professional of TARDIS", typically "physician James McCrimmon". The place Time-Lords get their names from remains to be somewhat not sure although the talk on the mobile with the master seems to indicate that they select their possess names someday in their lives (perhaps the coming of age or graduating/coming into the Academy?). As implied within the woodland of the dead, the doctor has only one time in his life that he can disclose his name to an individual, consequently being River song understanding his true identify. What this occasion is will expectantly be revealed in a later series, even though now not with his exact identify. From what i know, the prior sequence of healthcare professional Who would not say the physician names as it could defy the title of the show general practitioner WHO pronouncing that nobody is aware of what his identify. I do not believe that there was a point out of the physician's real identify, although i couldn't wager my lifestyles on it.
