Born about 1865 in Cincinnati, Len Lanius began wrestling around the age of 12, eventually wrestling on the Vaudeville circuit before retiring and joining the Sports staff with the Cincinnati Post. Lanius claimed to have held the title of Lightweight Champion Wrestler of the World, which would have been around 1890.After the famous Gotch-Hackenschmidt matches of 1908, Lanius started developing his "American Jiu Jitsu." In his own words, "it was the invasion of the Jap wrestlers around that time that put me to work on perfecting a style of defense to check their attack. Their methods were quite baffling."In March of 1921, Lanius demonstrated his creation, "Yankee Jiu Jitsu," to the Rotary Club and, again in June of 1921, he demoed his Jiu Jitsu to the Kiwanis. In 1922 he published this book, "American Jiu Jitsu."Special thanks to Jason Couch and the Martial History Magazine for making the original of this document available for republishing.
