I was delighted to find an interview with James Naismith where he discusses what drove him to invent the game. It is rare to find such a wonderful primary source of information. Check out the other tabs on the interview page. I hope you all enjoy it as much as I did!
For more information about how this interview came to light, check out this article from the University of Kansas. Not only do we have the rare recording available, but we have the story of its discovery!
