Robby Brown is an American Cave Diver and explorer. He is a recognized expert on the life and work of his close friends and mentors, the legendary cave diving pioneers, Bill “Hogarth” Main and Capt. John Zumrick, M.D.

One of his fascinations is the democratization of misinformation and downright false statements that propagate Wikipedia all too frequently.
