I think I am right that Dan Inosanto's original training in MA was as a Judoka before he met up with BL,
From an online biography I found:
" Inosanto gained his first instruction in the martial arts during the summer between his fourth and fifth grades in school. His uncle taught him techniques in jujitsu and Okinawan karate.
"But I never really took an interest in such things until I got to college," he said. Attending Whitworth College in Spokane, Washington, where he got his B.A. degree, Inosanto studied judo and karate."
