Trying to find an Aikido classmate
My father graduated Pace Univ. in 1967 his friend/aikido instructor ( he studied a little aikido and hapkido in the late 60s early 70s) was a Sandan in '67 named Bob Weisblatt and my father would like to look him up. I've ha no luck finding this sempai but promised my dad I'd try very hard to find him. He'd be 65 or thereabouts.
I am thinking there weren't many places to study Aikido in the early-mid 60s in NYC where one would rank Sandan.
Any help would be greatly appreciated.
