Scuba History

Scuba history from a diving bell developed by Guglielmo de Loreno in 1535 up to John Bennett's dive in the Philippines to amazing 308 meter in 2001 and much more...

Humans have been diving since man was required to collect food from the sea. The need for air and protection under water was obvious. Let us find out how mankind conquered the sea in the quest to discover the beauty of the under water world.

1535	A diving bell was developed by Guglielmo de Loreno.
1650	Guericke developed the first air pump.
1667	Robert Boyle observes the decompression sickness or "the bends". After decompression of a snake he noticed gas bubbles in the eyes of a snake.
1691	Another diving bell a weighted barrels, connected with an air pipe to the surface, was patented by Edmund Halley.
1715	John Lethbridge built an underwater cylinder that was supplied via an air pipe from the surface with compressed air. To prevent the water from entering the cylinder, greased leather connections were integrated at the cylinder for the operators arms.
1776	The first submarine was used for a military attack.
1826	Charles Anthony and John Deane patented a helmet for fire fighters. This helmet was used for diving too. This first version was not fitted to the diving suit. The helmet was attached to the body of the diver with straps and air was supplied from the surface.
1837	Augustus Siebe sealed the diving helmet of the Deane brothers' to a watertight diving suit and became the standard for many dive expeditions.
1843	The Royal Navy established the first diving school.
1865	An underwater breathing apparatus was developed and patented by Benoit Rouquayrol and Auguste Denayrouse. A steel tank filled with compressed air was connected to a valve and a mouth-piece. The tank was strapped to the divers back and the diver was tethered to the surface by a hose that pumped fresh air into the low pressure tank. The diver was able to disconnect the tether and to dive with the tank on his back for a few minutes.
1877	The first workable, self-contained diving rig that used compressed oxygen was developed by Henry A. Fleuss.
1893	Louis Boutan invented the first underwater camera.
1908	Detailed studies on the cause and symptoms on decompression thickness were published by John Scott Haldane, Arthur E. Boycott and Guybon C. Damant.
1911	Draeger of Germany introduces an oxygen re-breather.
1912	The U.S. Navy tested decompression tables published by John Scott Haldane, Arthur E. Boycott and Guybon C. Damant.
1917	The Mark V Diving Helmet was introduced by the U.S. Bureau of Construction & Repair. The Mark V Diving Helmet was used for most salvage work during World War II and became the standard U.S. Navy Diving equipment.
1923	W. H. Longley became famous for the first underwater color photos.
1924	The U.S. Navy and Bureau of Mines conduct first helium-oxygen experimental dives.
1925	A very successful self-contained underwater breathing unit is introduced by Yves Le Prieur.
1930	A bathysphere attached to a barge by a steel cable to the mother ship has been used for William Beebe descended to 435 meter.
1930	Rubber goggles with glass lenses are developed by Guy Gilpatric. Soon face masks and snorkels were in common use.
1933	Yves Le Prieur develops a demand valve with a high pressure air tank. In this way the diver became independent from hose connections to the surface.
1933	Swim fins are patented by Louisde Corlieu in France.
1934	Another descent to 924 meter in a bathysphere was undertaken by William Beebe and Otis Barton.
1935	Louis de Corlieu designed a very popular fin for divers.
1941	During World War II, closed circuit scuba equipment are used by Italian divers to place explosives under British naval and merchant marine ships.
1942	Jacques-Yves Cousteau and Emile Gagnan redesigned a car regulator that would automatically provide compressed air to a diver on his slightest intake of breath.
1943	The Aqua Lung was born. Jacques-Yves Cousteau and Emile Gagnan designed and tested the first Aqua-Lung. This device is a fundamental improvement on air supply for divers.
1947	A 94 meter dive record in the Mediterranean Sea was made by Dumas equipped with an Aqua Lung regulator.
1948	In California Otis Barton descended to a depth of 1372 meter in a modified bathysphere to.
1948	The first Aqua Lung regulators were imported to the USA and the diving community quickly adopted this new, convenient device.
1950	A completely self-contained new type of vessel called the bathyscaphe was designed by August Picard and his son Jacques to go deeper than any bathysphere.
1951	The Reserve Valve, later commonly known as "J" valve was developed.
1951	Hans Hass published "Diving as Adventure"
1952	"Silent World" was released by Jacques-Yves Cousteau, Frédéric Dumas, and James Dugan.
1953	"Underwater Safety" containing important basics on diving safety, was published by E. R. Cross.
1954	The National Cooperation in Aquatics published the "Science of Skin and Scuba Diving" and it becomes the main textbook for diver education.
1954	The television program Kingdom of the Sea starring Zale Parry is aired in the US. That same year Parry broke the depth record by diving to 64 meter near Catalina, CA. Her record attracted many female to scuba diving.
1955	The first formal instructor certification program was created by Al Tillman and Bev Morgan.
1956	At the University of California the first wetsuit is introduced by scientists and the red and white "Divers Down" flag was introduced by Ted Nixon.
1958	Sherwood Manufacturing announce the piston regulator.
1959	YMCA organized the first nationally scuba diver certification program and the Underwater Society of America was formed.
1960	Jacques Picard and Don Walsh descended to 10921 meter in the bathyscaphe "Trieste".
1960	Al Tillman and Neal Hess create the National Association of Underwater Instructors (NAUI).
1961	The National Association of Skin Diving Schools (NASDS) was founded by John Gaffney.
1962	A number of experiments were conducted whereby people lived in underwater habitats.
1963	In the "Man in the Sea" project Ed Link spends 24 hours at 61 meter.
1966	The Professional Association of Diving Instructors (PADI) was founded by John Cronin and Ralph Ericson.
1968	A dive to 133 meter, using compressed air, was carried out by John J. Gruener and R. Neal Watson.
1970	Bob Clark founded Scuba Schools International (SSI).
1971	Scubapro introduces the Stabilization Jacket.
1980	Divers Alert Network (DAN) was founded at Duke University to promote safe diving.
1981	A dive record to 686 meter was made at the Duke Medical Center decompression chamber.
1983	The first commercially available dive computer, the Orca Edge, was introduced.
1985	The wreck of the Titanic was found.
1990	Further improvements and developments are taking place and find it's way into the scuba diving sport. The use of mixed gases, like Oxygen and Helium, full face masks, underwater voice communication, propulsion systems, computer, etc. became more common in the 1990s.
1994	Bret Gilliam and Mitch Skaggs formed Technical Diving International (TDI)
1998	Scuba Diving International (SDI) was created.
1999	Chuck Driver and John Bennett descend to 200 meter. The deepest oceanic dive ever completed. The same year Barte Vestor set a challenging 225 meter mark.
2001	John Bennett breaks his own world record with a dive to amazing 308 meter.
