George Ivanovitch Gurdjieff (1872 - 1949), Russian born teacher. He became a follower of Sufism (an
Eastern religion) after travels in
Asia, which he then practiced and taught in an institute he founded in
France.
Or we see he's walking around on a squirrel cage, "Wasn't this actually developed at one time or another by Gurdjieff?" See, or Goodgief or Harold Bell Rightus, or something.
