Given the question: Information: - Frederic Dumas (14 January 1913 26 July 1991) was part of a team of three, with Jacques-Yves Cousteau and Philippe Tailliez, in which he was nicknamed Didi. They had a passion for diving, and developed the diving regulator with the aid of the engineer Emile Gagnan. Frederic Dumas then participated with Jacques-Yves Cousteau in the discovery of the underwater world and in bringing it to the attention of the general public. - Columbia Pictures Industries, Inc. (known professionally as Columbia Pictures and Columbia, and formerly CBC Film Sales Corporation) is an American film studio, production company and film distributor that is a member of the Sony Pictures Motion Picture Group, a division of Sony Entertainment's Sony Pictures subsidiary of the Japanese conglomerate Sony. The studio was founded in 1918 as Cohn-Brandt-Cohn Film Sales by brothers Jack and Harry Cohn and Jack's best friend Joe Brandt, released its first feature film in August 1922. It adopted the Columbia Pictures name in 1924, and went public two years later. Its name is derived from "Columbia", a national personification of the United States, which is used as the studio's logo. In its early years, it was a minor player in Hollywood, but began to grow in the late 1920s, spurred by a successful association with director Frank Capra. With Capra and others, Columbia became one of the primary homes of the screwball comedy. In the 1930s, Columbia's major contract stars were Jean Arthur and Cary Grant. In the 1940s, Rita Hayworth became the studio's premier star and propelled their fortunes into the late 1950s. Rosalind Russell, Glenn Ford, and William Holden also became major stars at the studio. - Scuba diving is a mode of underwater diving in which the scuba diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater. Scuba provides the diver with the advantages of mobility and horizontal range far beyond the reach of an umbilical hose attached to surface-supplied diving equipment (SSDE). Scuba divers engaged in armed forces covert operations may be referred to as frogmen, combat divers or attack swimmers. - A diving regulator is a pressure regulator that reduces pressurized breathing gas to ambient pressure and delivers it to the diver. The gas may be air or one of a variety of specially blended breathing gases. The gas may be supplied from a scuba cylinder carried by the diver or via a hose from a compressor or high pressure storage cylinders at the surface in surface-supplied diving. A gas pressure regulator has one or more valves in series which reduce pressure from the source, and use the downstream pressure as feedback to control the rate of flow and thereby the delivered pressure, lowering the pressure at each stage. - This article is about the book . For the 1956 documentary see The Silent World The Silent World ( subtitle : A story of undersea discovery and adventure , by the first men to swim at record depths with the freedom of fish ) is a 1953 book co-authored by Captain Jacques - Yves Cousteau and Frederic Dumas and edited by James Dugan . Although a French national , Cousteau wrote the book in English . Cousteau and Emile Gagnan designed , built and tested the first '' aqua - lung '' in the summer of 1943 off the southern coast of France . In the opening chapters Cousteau recounts the earliest days of scuba diving with his diving companions Frederic Dumas and Philippe Tailliez . The aqualung allowed for the first time untethered free - floating extended deep water diving and ushered in the modern era of scuba diving . Later chapters include excursions diving ship wrecks . It was the basis of the Academy Award - winning documentary The Silent World ( 1956 ) . It has been very successful ; as of the book 's 50th anniversary it has been translated into some 22 languages and sold over 5 million copies and is still in print , notably as a 2004 hardcover edition published by the National Geographic Society . The book contains 48 pages of black - and - white photos by various photographers , and 16 pages of color made available by National Geographic Magazine . The hand - held work in Ektachrome '' is the first ever made in significant depths , using artificial light and scientific color correction . '' - Louis Marie Malle (30 October 1932 23 November 1995) was a French film director, screenwriter, and producer. His film "Le Monde du silence" won the Palme d'Or in 1956 and the Academy Award for Best Documentary in 1957, although he was not credited at the ceremony with the award instead being presented to the film's co-director Jacques Cousteau. He was later nominated multiple times for Academy Awards later in his career. Malle is also one of the few directors to have won the Golden Lion multiple times. - The Silent World is a 1956 French documentary film co-directed by the famed French oceanographer Jacques-Yves Cousteau and a young Louis Malle. "The Silent World" is noted as one of the first films to use underwater cinematography to show the ocean depths in color. Its title derives from Cousteau's 1953 book "". It was released in the United States by Columbia Pictures. - Philippe Tailliez (15 June 1905, Malo-les-Bains 26 September 2002, Toulon, France) was a friend and colleague of Jacques Cousteau. He was an underwater pioneer, who had been diving since the 1930s. - Engineers design materials, structures, and systems while considering the limitations imposed by practicality, regulation, safety, and cost. The word "engineer ("from the Latin "ingeniator"")" is derived from the Latin words "ingeniare" ("to contrive, devise") and "ingenium" ("cleverness"). The foundation education of an engineer is typically a 4-year bachelor's degree or in some countries, a master's degree in an engineering discipline plus 46 years peer-reviewed professional practice culminating in a project report or thesis. Engineers who seek a professional engineer license in N. America will be required to take further exams in ethics, law and professional practice. - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux. - Underwater diving is the practice of descending below the water's surface to conduct underwater activities. In ambient pressure diving, the diver is exposed to the pressure of the surrounding water, and uses breathing apparatus for scuba diving or surface supplied diving, or when freediving, will breath-hold. The saturation diving technique reduces the risk of decompression sickness after long duration deep dives. Atmospheric diving suits may be used to isolate the diver from the effects of high ambient pressure. Although not usually considered to be diving, crewed submersibles can extend depth range, while remotely controlled or robotic diving machines can reduce the risk to human divers. - Toulon (Provencal : "Tolon" , "Touloun" ) is a city in southern France and a large military harbour on the Mediterranean coast, with a major French naval base. Located in the Provence-Alpes-Cote-d'Azur region, Toulon is the capital of the Var department. - James Dugan (May 7, 1912 - June 3, 1967) was a historian, editor and magazine article writer. Born in Altoona, Pennsylvania he is best known for his collaborations with Jacques Cousteau. - Emile Gagnan (November 1900 1979) was a French engineer and, in 1943, co-inventor with French Navy diver Jacques-Yves Cousteau of the Aqua-Lung, the diving regulator (a.k.a. demand-valve) used for the first Scuba equipment. The demand-valve, or regulator, was designed for regulating gas in gas-generator engines, but was found to be excellent for regulating air-supply under varied pressure conditions. This allowed people to explore the ocean more easily, even though the original purpose was different.
