Greg Noll (né Lawhead; February 11, 1937 – June 28, 2021) was an American pioneer of big wave surfing and a prominent longboard shaper. Nicknamed "Da Bull" by Phil Edwards in reference to his physique and way of charging down the face of a wave, he was on the U.S. lifeguard team that introduced Malibu boards to Australia around the time of the 1956 Summer Olympics in Melbourne. He produced a "legendary" series of five Search for Surf films.
