David Jacobs Biography

David Jacobs was born on December 6, 1966, in Easton, Pennsylvania, United States of America.

His interest in athletic endeavors started at the age of 11 through wrestling, a sport he practiced through junior high, high school, and college (Division 1). Later, Jacobs turned to weightlifting which he practiced religiously for 12 years.

In 1997 David came across the Ultimate Fighting Championship (UFC) while dining at a friend’s home. The fights sparked Jacobs’s curiosity, particularly the jiu-jitsu dynamics of the matches which reminded him of the wrestling he had practiced in school. A few months later, in February 1998 Dave took his first of many classes at the Yamasaki Academy. In a 2012 interview for the BJJ Blog – Meerkatsu, Jacobs wrote about his early experiences with jiu-jitsu “I walked into my first class thinking I was going to crush everyone because of my wrestling and weightlifting. Well, not surprisingly, my expectations turned out to be not so realistic. I got tapped repeatedly mostly by guillotines that day by guys who were much weaker than I was. That experience really lit a fire under me to learn jiu-jitsu.”

Known by the mainstream MMA audience as a referee for the UFC, Mario Yamasaki was the first jiu-jitsu instructor in the DC metro area. The Brazilian had a more traditional approach to BJJ, heavily reliant on a solid understanding of the foundations of the art and with a strong stand-up element, a style of coaching truly suited for an athlete of Jacobs’s background. Both Mario and Francisco Neto closely followed Dave’s progress in the sport.

Although pursuing a career as an attorney while being highly active in the East Coast competition scene – arguably the most active BJJ athlete in that area at the time, Dave still found the time to open his own training location in early 2004,  teaching at the aerobics room inside a Gold’s Gym a few times per week. As a result of Jacobs’s extensive competition record and improved methods of teaching, Dave finally received his black belt from Mario Yamasaki at a ceremony held in April 2005.

While setting an impressive pace in the tournament scene, coaching BJJ as well as pursuing a career in a particularly demanding field, Jacobs still found the time to study the International Brazilian Jiu Jitsu Federation (IBJJF) rule book and become one of the very first North American members of the federation’s refereeing body. This at a time when referee courses were only taught in Portuguese.

In 2007 Jacobs co-founded Fairfax Jiu Jitsu alongside Mark Jones and Sam Kim, a gym located in western Fairfax County, Virginia where Dave perfected his coaching skills until 2013. During the Summer time that year Jacobs left Fairfax JJ to form his own academy – David Jacobs Jiu-Jitsu Team.

On January 6, 2018, David Jacobs passed away due to a stroke at the young age of 51. Dave’s many epic matches – particularly while competing in the Grapplers Quest circuit, his pioneering work as a BJJ instructor and referee, and insightful participation on internet forums such as Sherdog and the UG made him a true educator and standard bearer for jiu-jitsu in the East Coast of the United States, particularly in the state of Virginia. A true BJJ Hero.

    Glad to see a BJJ Heroes page for him. What a wonderful man and a true jiu jitsu pioneer here in the U.S. One of the best referees I ever saw and you always knew he was going to be fair. He is sorely missed.

  • Stuart Waters says:

    I Ran into him in Sept. 2017 at the Maryland Ibjjf tournament in Landover. He told me then that he had a stroke a while back, great guy and family man. I trained with him at the Yamasaki Academy Rockville MD. in 06-07. My heartfelt condolences go out to his three children.

  • Steven Jones says:

    I had the pleasure of having dinner with Professor Jacobs and Professor Chris Hauter just a couple of months before his passing. I can’t remember much of what was said but I remember thinking about how cool it was to be there discussing “the old days” with the two of them. It was only after hearing of Professor Jacobs death that I realized how special that dinner truly was for me. My Jiu Jitsu is better for having trained with him but I’m a better person for knowing him off of the mat as well. RIP
