The use of diving bells is recorded by the Greek philosopher Aristotle in the 4th century BC.

Apneist Jacques Mayol became the first man to reach a depth of 100 m undersea without breathing equipment on November 23, 1976.

Director James Cameron pitched the motion picture Titanic to the film studios so that they would fund his diving expedition; not because he wanted to make the movie.

On March 26, 2012, Cameron reached the bottom of the Mariana Trench, the deepest part of the ocean, in the Deepsea Challenger submersible. He was the first person to do this in a solo descent, and is only the third person to do so ever. The data Cameron collected resulted in interesting new finds in the field of marine biology, including new species of sea cucumber and squid worm.

Egyptian scuba diver Ahmed Gabr set a new record on September 19, 2014 for the deepest salt water scuba dive, at 1,066 feet. The 14-hour feat took Gabr down into the abyss near the Egyptian town of Dahab in the Red Sea, where he works as a diving instructor.

The Bajau peoples of South East Asia are the first known humans that are genetically adapted to dive. Their bodies are genetically modified for diving, so much so that they can dive at around 200 ft deep for as long as 13 minutes.

Scuba stands for Self-Contained Underwater Breathing Apparatus.

Nitrogen narcosis, a shift in consciousness experienced by deep divers in high-pressure water, produces a state similar to drunkenness. After descending 50–70 meters (165–230 feet), divers have reported sleepiness, confusion, and hallucinations.

Divers working on deep-sea infrastructure such as oil pipelines live in a pressurized chamber for a month, taken between the chamber and their work-site by a pressurized diving bell. That way, they only need to be decompressed once, at the end of each 28-day job.
