Bret Gilliam was born at the United States Naval Academy in Annapolis, Maryland, to Commander Gill Gilliam (retired as Captain) and Jeanne Gilliam. He was the first of three children. His younger brother Chris was murdered in 1972 at the age of 16 while attending an outdoor concert in Puerto Rico.

Education

In 1959, the YMCA developed the first nationally organized course and certified their first skin and scuba diving instructors,[3] and Gilliam began his diving training with Lt. Chuck Brestle while his family was stationed at the Naval Air Station Key West that same year.[4][5]

From 1965 to 1967 he attended Virginia Beach High School until the school system split students to attend the newly created First Colonial High School. He remained at First Colonial High School until 1967 when his father was transferred to Brunswick Naval Air Station as Senior Executive Officer. He graduated from Brunswick High School in Brunswick, Maine, in 1969. While in high school, he was a stand-out athlete playing football, ice hockey, and baseball while also swimming and running track. He also was sponsored (NOT VERIFIED)as a surfing competitor for Hobie and Hansen (NOT VERIFIED)surfboards and participated in contest events on the east and west coasts (and Caribbean) as well as promotional sales activities (NOT VERIFIED)for those manufacturers from 1965 to 1970.

Gilliam then went on to attend the University of Maine and Bowdoin College where he studied history and political science.[5] He won a National ROTC Scholarship in 1968 and was scheduled to be commissioned as an Army officer when he was recruited to do alternate service on a Navy deep diving project filming nuclear fast attack submarines(NOT VERIFIED). Gilliam left his undergraduate studies early to join the Navy project and then went on to pursue a business career by starting Ocean Tech.[5]

Career

According to Gilliam, he held several diving jobs and competed as a semi-professional surfer (NOT VERIFIED)while in high school and college.[5]

In 1971, Gilliam was a diving Supervisor for Vocaline Air Sea Technology (VAST Inc.). The VAST Inc. contract took him to the Caribbean where he worked to develop nitrox and decompression procedures for their dive teams.[6] It was here that Gilliam's interest in underwater photography began. Their work was to record the "visible wake vortex that came off the propeller" of submarines.[4] In 1972 off the island of St. Croix, Gilliam's dive buddy Rod Temple was attacked by oceanic whitetip sharks during a project and was killed. Gilliam was cited for heroism by the Virgin Islands' Governor for his attempt to save Temple when he broke off his decompression and swam back into the attack. Both divers were dragged to depths in excess of 350 feet during the struggle before Temple was torn from Gilliam's grasp.[7] Gilliam survived an out-of-air free ascent from extreme depth and had to be evacuated to Puerto Rico to be treated for decompression sickness.[4][7] That same year, he also created his consulting company Ocean Tech in the U.S. Virgin Islands.

V.I. Divers Ltd. was founded by Gilliam in 1973 in St. Croix as a dive resort that not only catered to recreational divers but also scientific divers.[6] The company (and others that followed) also had a filming and studio support division that provided location services for boats, diving, equipment, helicopter & aircraft, stunt persons, and local logistics for Hollywood movies, television series, documentaries, and tourism promotions.

This was the world's largest sport diving operation in history. Gilliam also began conducting research on dive computer safety during this time[9] and remained with Ocean Quest until the company was sold to Sea Escape Cruise Lines in the fall of 1990.

(According to articles written by Gilliam, but not officially verified), Gilliam performed a deep air dive on February 14, 1990, at a site named "Mary's Place" in Roatán to 452 feet (138 m).[8][10] (According to articles written by Gilliam, but not officially verified) Gilliam later reached 475 feet (145 m) in October 1993 to better his own record.[8][10]
