A very good resource are Thomas Kuhn's interviews with Dirac [1]. He talked about his childhood (they barely spoke anything at home, because they had to talk in French...), his university studies and his findings. It is quite long but worth it!
This is great material!
I wonder if the recordings are available somewhere on-line to the public.
As they have a lot of material of other important physicists too, I would be very interested. They have some voice clips online, so I hope they will release the full interviews one day.
