Looking at the history of Kyokushin

I'm on a personal quest for the next little while to learn more about the history of Kyokushin Karate.

I would like to know more about the various people who helped to form, and evolve our style. I started researching people like Andy Hug, Jacque Sandulescu, Jon Bluming, and others. ( I'm sorry that I do not include their titles, but I'm not sure which title to use.)

Oh.. it's a vast sea of information all over the place.. and I'm so limited in time during the day!! But then, I have a lifetime to look for this, so I'll be patient, and keep reading.
