Lawrence Revere was both an author and a serious player. He died in 1977. His only book, Playing Blackjack as a Business, initially published in 1969, is still in print. If you look at the "true count" methods being employed pre-Revere, you will see why Revere was inducted into the hall of fame.
The earlier methods were cumbersome and mentally fatiguing to use. In the second edition of Beat the Dealer, in which Thorp first proposed the Hi-Lo Count, he mentioned a simplified method of using the count, though he failed to develop it as a full system. Revere had a leap of brilliance that led him to come to the conclusion that the simplified method of obtaining a "true count" that Thorp had mentioned could be fully developed and employed with the most powerful of point count systems. Revere's method was so simple compared to the alternatives, it has been employed by virtually every serious balanced point count system developer since, including Stanford Wong, Ken Uston, Lance Humble, Bryce Carlson, Arnold Snyder, and others. As a serious player, Revere's knowledge of blackjack included such esoteric techniques as shuffle tracking and hole card play.
