Hiroshi Wajima (The Great Wajima)... he was the sport's 54th and remains the only wrestler with a collegiate background to reach that rank.
Though, I suspect we're talking sumo and not international style (FS/GR.)
Saw him on TV when the tournaments(basho) were on, when I was stationed @ MCAS Futenma in '78/'79.
Stars & Stripes would show the daily results.
He was one of my favorites.
