Fearless 1970s Pipeline specialist from Hawaii. Dunn was born (1957) in Newport Beach, California, won the 11-year-old division of the 1967 Menehune contest in La Jolla, and two years later moved with his mother to Maui. He was featured in a 1970 Surfing magazine article titled "Jack is Nimble, Jack is Quick," which showed the white-blond 13-year-old goofyfooter dropping into a double-overhead wave at Honolua Bay.
The '70s would be Gerry Lopez's decade as reigning king of Pipeline, but Dunn, along with Rory Russell, was right there in the vanguard. He competed at times, finished third in the 1975 Pipeline Masters, but is best remembered for his arms-spread do-or-die approach to free-surf sessions.
Dunn appeared five times on the cover of Surfer and Surfing magazine between 1971 and 1980, and was featured in nearly a dozen surf movies, including Cosmic Children (1970), Going Surfin' (1973), Super Session (1975), and In Search of Tubular Swells (1977). He also did stunt-double surfing for Warner Brothers' 1978 surf movie Big Wednesday.
