8. WALLY THOM
This Birkenhead southpaw was successful in three distinct phases of the sport. First, he won middleweight silver at the 1947 European Amateur Champs when really only a welterweight; then as a pro he held British, Empire (now Commonwealth) and European welter crowns; and finally he became a prominent referee, handling the Rodrigo Valdez-Bennie Briscoe world middleweight title bout in 1977.
