ROBERT DRYSDALE

Robert Drysdale is one of the most successful Brazilian-American competitors of the late 2000s and the most influential BJJ historian of the modern era. Born in Salt Lake City in 1981 to a Brazilian mother and raised in both Brazil and the United States, Drysdale won the ADCC absolute division in 2007 and the IBJJF Mundial at heavyweight in the same year — establishing himself as one of the dominant absolute-division competitors of his generation alongside Roger Gracie.

Drysdale's competitive style emphasized closed guard, half guard, and an unconventional willingness to use wristlocks as primary finishing techniques. His matches against Roger Gracie, Buchecha, and the heavyweight roster of his era produced some of the most technically intricate absolute-division matches in IBJJF and ADCC history. After active competition Drysdale founded Drysdale Jiu-Jitsu in Las Vegas, which has become one of the most productive academies in the western United States.

Drysdale's most lasting contribution to BJJ, however, is his historical and journalistic work. His book Opening Closed Guard: The Origins of Jiu-Jitsu in Brazil (2022) is the most comprehensive academic treatment of BJJ's origins ever produced, and it substantially revised the conventional Gracie-centric narrative of the art's development by foregrounding the Luiz França lineage, the broader Brazilian-Japanese diaspora context, and the historically-contested questions about who developed which techniques and when. The book has been the subject of extensive discussion and some controversy within the Gracie family but is now considered the standard reference for serious historical study of the art. As of 2026 Drysdale continues to run Drysdale Jiu-Jitsu and produces ongoing historical and analytical work on the sport.
