R.I.P.
Don't know much about him at all, he has been more or less just a name. But recently there has been a few discussions where his name has come up, so I tried to do a bit of research. I've only heard good things about him as a teacher and practitioner.
I read this article just for a few weeks ago. I like it, it's a very nice portrait of the man that gives a sense about his philosophy and how he taught.
It's hard to find video clips with this gent. This "Tai Chi with Ben Lo 2004" vid has an old documentary style which makes it look more like something recorded in the early 1980s.
