Influential figures
People whose work changed what the rest of us do on the mat, in alphabetical order. Every claim is sourced, and where the record is contested — which in jiu-jitsu is often — the entry says so.
This is not a ranking. It is not ordered by anything except the alphabet, and nobody’s absence from it is a verdict.

1902-1994
Carlos Gracie
He turned a few years of instruction in an Amazon theatre into an institution, and the machinery he built - an academy, a family, and a standing public challenge - is why one household's version of the art is the one that travelled.

1932-2006
Carlson Gracie
He replaced the private lesson with the group class and built his academy around sport competition, trends BJJ Heroes credits to him and that the sport kept.

1913-2009
Helio Gracie
He fought in public across two decades, from 1932 to 1955, under rules that barely existed, and the losses in that record did more to shape what the family taught than the wins did.

born 1985
Kyra Gracie
She competed at the top of women's jiu-jitsu against the stated wishes of the family whose name is on the art, at a point when the women's divisions were small enough that visibility and survival were the same problem.

born 1983
Marcelo Garcia
He won at the top of no-gi grappling with a deliberately small set of positions, and then taught that set in public, which changed what a competitive game is expected to look like.

1878-1941
Mitsuyo Maeda
The Kodokan judoka whose club in Belem is the point where nearly every Brazilian jiu-jitsu lineage chart begins, and the point at which the documentation stops agreeing with itself.

1921-2005
Oswaldo Fadda
He taught in the Rio suburbs rather than the wealthy south zone, and in January 1955 he publicly challenged the Gracie academy - which is why the sport has an argument about lineage at all.

born 1958
Rickson Gracie
He took the family's claim to Japan in the mid-1990s and won there, and the 400-fight record repeated in his name is the best-known unverifiable number in the sport.

born 1981
Roger Gracie
He won at the highest level of the gi ruleset with the mount and the cross choke, the two things every beginner is taught in the first month, and made the case that the basics were never the problem.

born 1966
Royce Gracie
On one night in Denver in 1993 he won three fights in a total of under five minutes of mat time, in front of a paying audience and a camera, and the argument about whether grappling mattered changed for good.
