IANTD (IAND, Inc.) was founded by Dick Rutkowski, the former dive supervisor for the National Oceanic and Atmospheric Administration (NOAA). Mr. Rutkowski introduced the recreational diving community to the technology of EANx. This program was developed through NOAA during his tenure.
Today the board of directors and the membership of IANTD are composed of many of the most experienced divers in the world pertaining to the use of breathing gases other than air..
IANTD did struggle in the early years. As it was the first program to offer certification in Enriched Air Nitrox, the company was kept at a slow, yet steady pace from 1985 through February of 1992 with the support of Hyperbarics International. In 1991 Tom Mount joined Dick and IANTD became the FIRST to offer training programs in all aspects of technical diving (Advanced Nitrox, Deep Air, Technical Diver, Cave and Wreck Penetration, Normoxic Trimix, Trimix, Expedition Trimix,Rebreathers, etc.) and now Free Diving too! .
