What is known about the Doctor's childhood, or at least the time before the classic series? There's some stuff about him being half human, some stuff about a different universe Doctor, some about his history is always changing and some is about him being a loom. I know extended canon sometimes clashes but still, is there any definite canon?

(Please try to avoid spoilers from after “End of Time”.)

    "Definite canon" are not words that can be applied to Doctor Who.

    Answering this question would spoil something that happened way after The End Of Time. When you get to series 8 (Capaldi's first) you'll see an episode with a child Doctor.

  • There was definitely a barn involved at some point. Commented Feb 22, 2018 at 9:47
  • Firstly, when has the doctor ever been references as being partly human? He's taken the form of a human as a disguise, and there is a clone of him that is part human, but afaik the doctor is 100% timelord. Secondly, I don't think it appropriate to ask us to limit an answer to a specific period of episodes so we don't spoil it for you. If you think it might be explained in a newer episode, watch them for yourself.

There is no answer to your question fitting your criteria. There was an episode Listen that occurred outside of your criteria that showed a child Doctor

It has been stated on occasion (I believe within your criteria), that the Doctor looked into the Infinite Schism as a child, went to the Time Lord Academy (for centuries), was nicknamed Sigma Theta at one point.

That is all that I can remember, as I haven't actually watched pre-revival episodes of Doctor Who

PS: More data about this question can be obtained by widening the criteria to include all of Capaldi's era


Speaking ONLY from the original 7 doctors...

  • In the final key to time story he meets drax, a chum from school days. He calls baker "feet" (from "feeta sigma").

  • In the thing in the pit doctor says he was born under sign of "crossed computers" the gallifrean maternity service symbol.

  • Heres one VERY few people catch; in the brain of morbius the doc fights him at "mind bending" and each timelord reveals the sequence of his lives on the monitor. And guess what? THERES A GUY BEFORE HARTNELL!
