Winning most of his professional matches in less than 10 minutes and a claimed career record of more than 2,000 wins and 5 losses, George "the Russian Lion" Hackenschmidt, was considered the top wrestler of his day and is even now considered one of the top Catch-as-catch-can wrestlers of all time. First published in 1909 and lavished with 70 photographs, provides an introduction to what Hackenschmidt thought was the most important elements of Catch-as-catch-can wrestling, with particular attention to what was not included in competing manuals. Though he had earned a reputation as a true gentleman in the ring, his manual includes details on trips, leg-locks, arm-locks, chokes, skirting the rules, "punishing" holds, and various "tricks" that could be used in a match. This manual, faithfully transcribed by Kirk Lawson from the original, contains a wealth of information for modern Catch-as-catch-can wrestlers and remains an important and valuable wrestling resource to this day.
Georg Karl Julius Hackenschmidt was an early 20th-century Estonian Swedestrongman, professional wrestler, author, and sports philosopher who is recognized as professional wrestling's first world heavyweight champion who debuted in 1896 and retired in 1911.
It would probably be unfair to review this as a book per sé, but it's fascinating as a reference work to read the advice and explanations given therein on wrestling and other grappling arts, particularly wherever Hackenschmidt's own opinions and experience come to light - any glimpse into his world is a welcome one.
