Man has always longed to spend some quality time with the creatures of the deep blue.
Maybe it's because of the unknown nature of the ocean's depths. For centuries, it was largely a mystery, only viewed from topside. Tales of giant squid and other man-eating aquatic monsters are as much a part of seafaring history as schooners and frigates.
Jacques-Yves Cousteau was born in the village in southwestern France, on June 11, 1910.At age 4, Cousteau learned to swim and started a lifelong fascination with water. As he entered adolescence, he showed a strong curiosity for mechanical objects and upon purchasing a movie camera, he took it apart to understand how it operated.
Emile Gagnan was born in France and after graduating from technical school, went to work as an engineer for a large gas-supply firm. Gagnan was a prolific inventor and had developed everything from mechanical razors to butane regulators for automotive fuel systems. His superior had instructed him to cooperate with undersea explorer, Jacques Cousteau in any way, as his father-in-law was on the Board of Directors. Cousteau had been looking for a way to allow divers to remain underwater for several hours. Gagnan had just put together a regulator that would allow the use of cooking gas in an automobile. Gagnan and Cousteau decided that the cooking gas regulator was probably a better idea than the high-altitude breathing regulator. So with minor adaptations, this regulator became what Cousteau coined as "Aqua-Lung," the beginning of the modern-day SCUBA (Self Contained Underwater Breathing Apparatus). In 1943, Emile and Cousteau perfected the Aqua Lung and Cousteau and his team of divers began underwater testing in the Mediterranean Sea. A century-old dream became reality - the first automatic autonomous diving suit, equipped with pressure regulator and compressed air bottles, gave the diver complete independence of movement.
Hans Hass , the marine biologist, oceanographer and zoologist, who has died aged 94, was a pioneer — with his wife Lotte — of spectacular films of the sea depths, and in the mid-1950s shot the first underwater footage for the BBC. At a time when diving equipment was bulky and unreliable, Hass managed with just flippers, goggles and lightweight breathing apparatus that allowed him to get close to the undersea action . Many viewers, however, were more spellbound by Hass’s glamorous wife than by the mechanics of braving watery new frontiers . A fan of his since her school days, Lotte Baierl got a job as his secretary, and during a filming expedition to the Red Sea in 1950, the year she and Hass married, worked as both an underwater photographer and model.
Sri Lankabhimanya Sir Arthur Charles Clarke(16 December 1917 - 19 March 2008) was a British science fiction writer, popularizer of space travel, futurist, and inventor. He is perhaps most famous for being co-writer of the screenplay for the film 2001: A Space Odyssey, generally considered one of the most influential films of all time. His other science fiction writings earned him a number of Hugo and Nebula awards, along with a large readership, making him into one of the towering figures of the field. For many years he, along with Robert A. Heinlein and Isaac Asimov, were known as the "Big Three" of science fiction. Clarke was also a science writer, who was both an ardent proponent of space travel and a futurist of uncanny ability, who won several awards in the field. These all together eventually earned him the moniker "prophet of the space age".
Helene Bertha Amalie "Leni" Riefenstahl (22 August 1902- 8 September 2003) was a German film director, actress and dancer widely noted for her aesthetics and innovations as a filmmaker. Her most famous film was Triumph of the Will, a documentary film made at the 1934 congress in Nuremberg of the Nazi Party. Riefenstahl's prominence in the Third Reich, along with her personal association with Adolf Hitler, destroyed her film career following Germany's defeat in World War II, after which she was arrested but released without any charges. Triumph of the Will gave Riefenstahl instant and lasting international fame, as well as infamy. She directed eight films, two of which received significant coverage outside Germany. The propaganda value of her films made during the 1930s repels most modern commentators, but many film histories cite the aesthetics as outstanding.The Economist wrote that Triumph of the Will "sealed her reputation as the greatest female filmmaker of the 20th century". In the 1970s, Riefenstahl published her still photography of the Nuba tribes in Sudan in several books such as The Last of the Nuba. Active until her death at age 101, she published marine life stills and released the marine-based film Impressionen unter Wasser in 2002.
The most commonly used scuba set is the "single-hose" open circuit 2-stage diving regulator, stage connected to the cylinder valve and the second stage at the mouthpiece. This arrangement differs from Emile Gagnan's and Jacques Cousteau's original 1942 "twin-hose" design, known as the Aqua-lung, in which the cylinder pressure was reduced to ambient pressure in one or two stages which were all in the housing mounted to the cylinder valve or manifold.
