Jacques Mayol (1 April 1927 – 22 December 2001) was a French diver and the holder of many world records in free diving. The 1988 film The Big Blue, directed by Luc Besson was inspired by his life story and that of his friend, Enzo Maiorca. Mayol was one of the screenwriters and authored the book Homo Delphinus: the Dolphin Within Man of his philosophy about the aquatic origins of humans.
Jacques Mayol was a French national born in Shanghai, China. Mayol spent his summer vacations in Karatsu (Japan) every year as a child. When he was 7, he would skin dive with his older brother in seas around Nanatsugama (ja:七つ釜)(Karatsu,Japan), where he saw a dolphin for the first time. Mayol described the fateful encounter in his book, "Homo Delphinus: The Dolphin Within Man".
At 49, he was the first free diver to descend to 100 meters (330 ft) on 23 November 1976; and when he was 56, he managed to descend to 105 meters. During the scientific research phase of his career, Mayol tried to answer the question of whether man had a hidden aquatic potential that could be evoked by rigorous physiological and psychological training.
Mayol's lifelong passion for diving was based on his love for the ocean, his personal philosophy and his desire to explore his own limits. During his lifetime, he helped introduce the then elitist sport of free-diving into the mainstream. His diving philosophy was to reach a state of mind based on relaxation and yoga breathing, with which he could accomplish apnea. He also contributed to technological advances in the field of free-diving, particularly improving assemblies used by no-limits divers. He was also instrumental in the development of scuba diving's octopus regulator, which was invented by Dave Woodward at UNEXSO around 1965–6. Woodward believed that having the safety divers carry two second stages would be a safer and more practical approach than buddy breathing in the event of an emergency.
Mayol was already an experienced free diver when he met the Sicilian Enzo Maiorca who was the first to dive below 50m. Mayol reached 60m depth. A friendship, as well as rivalry between the two men ensued. Their most famous records were set in the no-limits category, in which the divers are permitted to use weighted sleds to descend and air balloons for a speedy ascent. Between 1966 and 1983, Mayol was eight times no-limits world champion. In 1981 he set a world record of 61m in the constant weight discipline, using fins. In 1976 Mayol broke the 100m barrier with a no-limits 101m dive off Elba, Italy. Tests showed that during this dive his heart beat decreased from 60 to 27 beats/min, an aspect of the mammalian diving reflex, a reflex more evident in whales, seals, and dolphins. Mayol's last deep dive followed in 1983 when he reached the depth of 105m, at the age of 56.
Mayol's fascination with dolphins started in 1955 when he was working as a commercial diver at an aquarium in Miami, Florida. There he met a female dolphin called Clown and formed a close bond with her. Imitating Clown, he learned how to hold his breath longer and how to behave and integrate himself underwater. It is the dolphins that became the foundation of Mayol's life philosophy of "Homo Delphinus".
Throughout his book L'Homo Delphinus (2000 published in English as Homo Delphinus: The Dolphin within Man by Idelson Gnocchi Publishers Ltd.) Mayol expounds his theories about man's relationship with the sea where he explores the aquatic ape hypothesis of human origins. He felt man could re-awaken his dormant mental and spiritual faculties and the physiological mechanisms from the depths of his psyche and genetic make-up to develop the potential of his aquatic origins, to become a Homo delphinus.
Jacques Mayol predicted that, within a couple of generations, some people would be able to dive to 200 m and hold their breath for up to ten minutes. Today the no-limits record stands at 253 m (Herbert Nitsch, June 2012). Serbian Branko Petrović holds the record for Static Apnea at 11 minutes and 54 seconds (October 2014). Croatian Goran Čolak holds the record for static apnea on pure oxygen at 23 minutes 1 second (June 2014).
