History

After
Jacques-Yves Cousteau Jacques-Yves Cousteau, (, also , ; 11 June 191025 June 1997) was a French naval officer, oceanographer, filmmaker and author. He co-invented the first successful Aqua-Lung, open-circuit SCUBA (self-contained underwater breathing apparatus). Th ...

to the market, there followed a growing interest in scuba diving by the public and a subsequent need to codify the training. In 1951, Jim Auxie Jr and Chuck Blakeslee started a magazine called ''The Skin Diver'' (later renamed ''Skin Diver Magazine''). Two-year dive teacher Neal Earl Hess contributed to its "The Instructors Corner" column to inform readers about scuba. He soon established a column called "The National Diving Patrol" as a section to name new skin and scuba diving "instructors." Still, no official training and certifying agency existed, except for the training and resources provided by the military (Underwater Demolition Teams) and dive clubs. In 1952, Al Tillman, the director of sports for the

, I ran into several divers in the water with me who didn’t know what they were doing. One had one of the new underwater breathing units that allows divers to stay under for long periods of time... I propose that my department get involved in this sport and provide training classes. I believe that diving will grow in the future and we have an obligation to make the sport as safe as possible." In 1955, Tillman and L.A. County lifeguard Bev Morgan created the L.A. County Parks and Recreational Underwater Instructor Certification Course (1UICC) in an effort to respond to the growing number of diver requests. It was the world's first civilian training program to certify recreational divers and soon began granting Provisional Certification to instructors across the country. In the May 1960 issue of ''Skin Diver Magazine'', the creation of The National Diving Patrol was announced as an official, national organization. Its purpose and function was "to insure competent underwater instruction and to reduce diving accidents through education.” In 1959, the name was changed to the National Association of Underwater Instructors (NAUI). Hess, Blakeslee, Auxier, and Tillman met in August 1960 to discuss and organize NAUI's first Instructor Certification Course. It was held at the Shamrock Hotel in Houston, Texas on August 22–26. During the six-day course, 72 candidates attended from the U.S. and Canada, but only 53 graduated. The 53 graduates and their staff instructors became the first instructor members of the National Association of Underwater Instructors. The NAUI ICC became the first course to make diver certification available worldwide. A year later, the second NAUI ICC was held in

NAUI Green Diver Initiative

In 2010, NAUI Worldwide formed the NAUI Green Diver Initiative (GDI). GDI was implemented to "empower individuals to preserve and conserve the ocean planet with the common goal of taking action to protect the environment." With stagnant progress, it was not until July 2015 that NAUI renewed its commitment to the Initiative, unveiling its first manager, Sam Richardson, who entered the full-time position with over 10 years of non-profit experience. GDI remained a U.S. registered 501 (c) (3) non-profit that relied on the support of donors to fulfill its mission.

It often involves the use of special gas mixtures (rather than compressed air) for breathing. NAUI standards for technical diving were developed by Tim O’Leary and published by NAUI Worldwide in 1997. NAUI's technical diving program requires special training, equipment, and qualified support teams. In 1997, the NAUI Technical Diving Division was created. NAUI formed a Technical Training Advisory Board and Rebreather Advisory Board, with Tim O'Leary as the chairman for each, to assist in the development of technical diving standards and training.
