Don't bother telling me he didn't invent Brazilian Jiu-Jitsu all by himself. Don't bother telling me it should be spelled "jujutsu" and it's really judo anyway. Don't bother telling me the Gracies are marketing machines.
I know all that. Doesn't matter. The fact remains that Helio Gracie was a fighter in an age of jobbers. A long age of jobbers. Every submission fighter, grappler, hobbyist and fan out there owes him a debt.
