Gary Gentile

Gary Gentile (born 1946) is an American author and pioneering technical diver.

Gary Gentile is a wreck diver. It has been suggested that Gary Gentile may be the most experienced wreck diver in the world. He has dived on the wreck of the SS Andrea Doria (sometimes referred to as the "Mount Everest" of SCUBA diving) over 190 times, and was the first diver to penetrate the first class dining room of the vessel. He was also part of the team of divers, along with Bill Nagle, who recovered the ship's bell in 1985.

During the early 1990s, Gentile pioneered the use of mixed gases in wreck diving. He has also participated in expeditions to the SMS Ostfriesland (at a depth of 380 feet), which would serve as the impetus for greater exploration of deep-water shipwrecks, and the RMS Lusitania (at a depth of 300 feet).

He achieved fame within the diving community with his publication of The Advanced Wreck Diving Guide in 1988. He also published the first book on technical diving, The Technical Diving Handbook, and the field began to gain recognition as a separate stratum of the sport from conventional recreational diving. In many of his books Gentile notes that before technical diving was recognised as a sub-stratum of the sport, divers who consciously engaged in planned decompression diving were shunned by major diver training agencies as "gorilla divers".

Gary Gentile has self-published 45 books. He has written several technical books relating to diving, as well as extensive documentation of the shipwrecks of North America. He has also published a number of futuristic fantasy fictional works, although none of these have been a notable commercial success to date.
