- National Association of Underwater Instructors
The National Association of Underwater Instructors (NAUI) is a non-profit 501(c)(3) association of SCUBA instructors. It was officially CE and ISO certified in May 2007 in all three diver levels and both instructor levels.
NAUI was founded by Albert Tillman and Neal Hess in 1959. In August 1960, NAUI's first Instructor Certification Course was held at the Houston’s Shamrock Hilton Hotel with 72 candidates. The following year, in October 1961, NAUI was incorporated in the State of California as a non-profit educational organization. Al Tillman was the first President and Neal Hess, the Executive Secretary. Other original board members included John C. Jones of the Red Cross and Garry Howland of the United States Air Force. NAUI Worldwide is an international non-profit training agency.
Captain Jacques-Yves Cousteau, the inventor of the aqualung, was on the board of advisors of NAUI, as was Albert R. Behnke, a pioneer of diving medicine. Actor Lloyd Bridges was the first honorary NAUI instructor member. He played frogman "Mike Nelson" in the American television series, Sea Hunt, which popularized scuba diving. Buster Crabbe, the famous Olympic swimmer and movie star, was a NAUI instructor. Other celebrities who are certified NAUI divers include Kevin Costner, Lou Gossett Jr., and Cameron Diaz; Tiger Woods is a NAUI divemaster member. Most of the top universities, colleges and institutes of technology in the United States certify diving students through NAUI, including the US Navy, SEALs, Army Special Forces, and NASA astronauts for civilian diving licenses.
NAUI was the first recreational training agency to sanction Nitrox training in 1992. It published standards for teaching technical diving in 1997, a practice that had been growing among NAUI members for several years. Training is provided ranging from Skin Diver through Instructor Course Director, with dozens of specialty courses. Thousands of member instructors, affiliated stores, resorts, and service centers are located in countries around the world.
