From Golf Rewind Wiki

Natural Golf or Single Axis Golf is a method inspired in the swing of Murray "Moe" Norman (1929-2004), an eccentric, self taught Canadian professional golfer who developed a completely unconventional yet effective technique. Norman did not coin the terms.

A firm called "Natural Golf" was founded in 1991 by Jack Kuykendall, who claims to have discovered the scientific principles that made Moe Norman's the optimal golf swing. Kuykendall hired Norman to conduct clinics.

Norman's followers promptly split into two branchs, one of them lead by Jack Kuykendall (Lever Power Golf) and the other lead by Tim and Todd Graves (Natural Golf). Kuykendall has harshly criticized the Graves for their technical positions and for having taken his company over [1] .

Other Moe Norman inspired methods are Tom Sanders' Big Grip Golf (BGG) and Jerry Heard's Super Swing.
