John Chatterton is one of the world's most accomplished and well-known wreck divers. He ws a co-host for 57 episodes of the popular History Channel series Deep Sea Detectives. He is also a consultant to the film and television industries and has worked with 20th Century Fox, Paramount Pictures, and CBS. Prior to his career in television, John spent twenty years working as a commercial diver in and around New York City, and was working underneath the World Financial Center, directly across the street from Tower #1, on 9/11/01.

His passion has always been researching and diving the deep shipwrecks of the world. The 1991 discovery and subsequent identification of the German submarine U-869 off the coast of New Jersey has been the subject of several television documentaries, including Hitler's Lost Sub, a two-hour special for the popular NOVA series on PBS. This same story is now the subject of a New York Times bestselling book by Rob Kurson, titled Shadow Divers. It is currently published in 21 languages. The movie rights to the international bestseller have been purchased by 20th Century Fox.

John was a member of the first technical diving expedition to Ireland and the legendary RMS Lusitania in 1994. A few years later, at a depth of 400 feet, he was the first diver to use rebreather diving technology on the wreck of HMHS Britannic, near the island of Kea in Greece. He was also the sole American on a British expedition, sponsored by the U.S. Holocaust Museum, looking for the historic shipwreck Struma in the Black Sea near Istanbul. These dives in Turkey were chronicled in the HBO documentary Struma. In addition, John has managed to make over 160 dives to the well known wreck of the Andrea Doria. Next >
