RIP & respect to Ad Santel, who passed away on this Day in Pro Wrestling History, November 10th, 1966.
What truly set Santel apart was his role in pioneering inter-style matches, effectively laying groundwork for modern mixed martial arts (MMA). In the 1910s and 1920s, Santel challenged prominent judokas from Japan's Kodokan, the birthplace of judo. He famously defeated several black belts, including Tokugoro Ito and Daisuke Sakai, in high-profile bouts that pitted Western catch wrestling against Eastern grappling arts.
Santel even claimed the title of "World Judo Champion" after these victories, though this was largely self-proclaimed and not officially recognized by the Kodokan. Santel may have had something to do with the Gotch-Hackenschmidt match when Hackenschmidt claimed his knee had been deliberately injured during training, rendering him unfit to compete at full strength. Years later, Santel himself confided to Lou Thesz that he had been paid by someone in Gotch's camp—possibly promoter Jack Curley or trainer Martin "Farmer" Burns—to sabotage Hackenschmidt by targeting his leg in a rough sparring session.
