Was there a time when it wasn't common knowledge that O'Sensei studied Daito Ryu? I ask because when I started in 2001 (yup, young'n) it was EVERYWHERE I looked that Daito Ryu was in Aikido's past. Is this just because I came into things post-internet, as it were?
Thanks be to Stan. Prior to him it was known, but greatly de-emphasized - included as one of the many things that Morihei Ueshiba trained in before making a completely original creation.
