George Greenough is an innovative surfer and cinematographer from Santa Barbara, California, who now resides in Byron Bay, NSW, Australia. He was born to a wealthy family but despised its trappings and spent most of his time in the ocean. Greenough is best known for creating the modern surfboard fin. He altered the design from a wide based, cumbersome keel to a more powerful and efficient dolphin fin-like foil.
In the 60's Greenough's equipment was distinctly different from the longboard design of the day, and he rode short kneeboards under 5'5" and air mattresses regularly. He is credited as being the best mat rider ever, and still surfs the unique waveriding craft. His most famous board was a fiberglass spoon using only small amounts of buoyant foam, shaped kneeboard he christened "Velo". Greenough is also known as a genius level inventor and the master of fiberglass engineering, design, and construction, having used the material to build surfboards, camera housings and boats.
In the late 1960s and early 1970s, George released two feature films The Innermost Limits of Pure Fun and Crystal Voyager. His footage above and below the water were personally selected by the members of Pink Floyd as the imagery for their "Echoes" film after the group saw Crystal Voyager, which used the Pink Floyd track as the music for the final sequence of the movie. Greenough is also featured in an early scene in Bruce Brown's surf film The Endless Summer.
