There are a few martial art geniuses in this city so it is a sore point.
I did not remember John Stevens's being listed as an author of Budo: Teachings of the Founder of Aikido but then again I was busy looking at the picis - it is a beautiful book. On Amazon there are a couple of other books by Morihei Ueshiba where John Steven's is listed as either editor or compiler but not for Budo. Of course that does not mean he did not have his hand in there. Kenji Tomiki apparently was one of those involved in producing the original Budo but understandably only Ueshiba is listed as author. A long tradition of student slave labour - I love it.
