Why Is Scuba Diving Called Scuba Diving?

If you have ever wondered how Scuba diving began, here is a history of the sport. Yves le Prieur is credited with the invention of scuba diving, but there are other contributors, such as Emile Gagnan and Jacques Cousteau. Syvlia Earle was also a pioneer in this area. In this article, we will explore these names and why SCUBA diving became so popular.

Scuba Diving Was Invented by Yves le Prieur

In the early 1940s, Yves le Prieur made scuba equipment possible by creating a detachable demand regulator and a diving suit. Until the early 1900s, the use of tethered breathing apparatus was the only practical option. During this time, Yves Le Prieur and Emile-Gagnan improved the air delivery mechanism and named the equipment Aqua-Lung. These specialized diving equipments allowed divers to untether themselves for short periods of time but did not allow for self-contained breathing.

The Le Prieur scuba system was the first self-contained breathing apparatus. It was a cylinder of compressed air carried by the diver on his back, a regulator, and two gauges on the regulator. These three parts supplied air continuously to the diver's mouthpiece. The diver ejected air through a small exhaust pipe. This made scuba diving more accessible and safe.

Jacques Cousteau

Jacques Cousteau and Scuba diving went hand in hand. Both men were fascinated with the ocean and its inhabitants, and both of them became passionate about it. During World War II, Cousteau and his family took refuge near the Swiss border and continued their underwater experiments. In 1943, Cousteau met Emile Gagnan, who shared his interest in discovery. The two men worked together to develop an underwater breathing apparatus.

During his explorations, Cousteau was frustrated with the inadequate equipment available to divers. The self-contained breathing apparatus invented by Yves Paul Gaston Le Prieur in 1926 was not effective, and allowed the diver to spend only a limited amount of time underwater. Cousteau began trying to breathe pure oxygen, but he suffered from oxygen toxicity at depths below 45 feet. Despite the limitations of these equipment, he persevered and finally found a way to regulate the air flow.

Emile Gagnan

When diving is called Scuba diving, it refers to the breathing apparatus used for scuba diving. The invention of the aqualung was credited to Emile Gagnan, who lived in France and was an engineer. He discovered that deep sea diving can be dangerous and that a person can suffer from nitrogen narcosis, which can cause extreme pain and crazy behavior. Gagnan and Cousteau collaborated on developing a machine to control air pressure and oxygen levels.

Originally, divers had to use helmets and diving bells to explore the sea. There was no way to provide the breathing apparatus on their own; they relied on a source of air that was connected to the surface. In 1937, Cousteau decided to develop an underwater breathing apparatus for divers and teamed up with Emile Gagnan, a gas-generating engineer from Paris. Together, they devised a demand valve system that delivered compressed air on demand and adapted to the pressure of the surrounding water.

Syvlia Earle

A pioneering oceanographer, Dr. Syvlia Earle dives with Scuba Diving to save our oceans. As an oceanographer, Earle has traveled the world, studying changes in the ocean's ecosystem. She has filmed abundant life and described light-emitting fish like miniature cruise ships. She describes spiraling corals and countless fish. Her enthusiasm is infectious, and her vivid recollection transports you to the depths of the ocean.

The first all-female submarine crew, Tektite II, spent 14 days underwater in the 1970s. The team spent twelve hours underwater each day. Upon their return, they ate food prepared for astronauts, but the majority of them preferred peanut butter and jelly sandwiches. The team was greeted with a ticker-tape parade, and the pioneering women were invited to meet President Nixon at a White House reception.

Yves le Prieur

Scuba diving was invented by Yves le Prieur in 1946. At that time, a fullface mask with a large, loose front plate acted as a demand regulator and confined the diver's air supply. Le Prieur's design, known as the "Fernez-Le-Prieur" mask, was patented and used as a standard respirator for recreational diving.

Famous Scuba divers, Jacques-Yves Cousteau and Philippe Tailliez began exploring the world's oceans by re-breathing with a single-hose regulator. This apparatus was a breakthrough in the underwater world and would change the way we breathe. The Aqua-Lung regulator was a masterpiece of miniaturization and was a breakthrough in underwater breathing.
