Thanks to the Gracie Academy for passing this on:
On Tuesday morning Grand Master Helio Gracie was tanning at his ranch in Brazil, and on Thursday morning at 9:15 he passed on due to natural causes. His legacy will survive forever in all members of the Gracie Family, jiu-jitsu practitioners around the world, and all those who have benefited from the revolution he began.
In his final years, the creator of Gracie Jiu-Jitsu often spoke of his satisfaction with his life’s work. He openly stated that he had accomplished everything he had set out to do, displaying his preparedness for the transition into the afterlife.
