"The little-known stories behind well-known inventions"

Beloved French inventor made underwater exploration possible

By Paul Niemann

[JUNE 22, 2006]  A Frenchman became known all over the world because of his award-winning TV documentaries and his seven books, yet many people don't realize that he was also an inventor.

His name means "John" when translated into English. He was born in Saint-Andre-de-Cubzac, France, in 1910. If you don't where that is, let me help you with your geography: It is located north of Spain and south of Belgium. France, that is. As far as the location of Saint-Andre-de-Cubzac, I have no idea where that is.

Unlike another Frenchman, Joseph Guillotin, he did not have his invention named after himself. (That didn't work out so well for Guillotin's children, by the way, who later changed their last name.)

This Frenchman's main invention allowed people to dive to underwater depths that were previously impossible to reach. The name of his invention is an acronym: self-contained underwater breathing apparatus, or SCUBA. Scuba allows divers to explore the ocean depths by breathing compressed air rather than oxygen.

The Aqua-Lung was his first version of scuba. It wasn't as efficient as the current type of scuba gear because it didn't recycle the same air that a diver would exhale. As a result, the Aqua-Lung (or aqualung) did not enable divers to stay underwater as long as the current version of scuba gear does.

The inventor, explorer and filmmaker traveled the waters in his boat, the Calypso, beginning in 1950. Calypso was used as a minesweeper before it was used for underwater exploration. The inventor with the red cap who became a household name aboard his Calypso was Jacques Cousteau. He co-invented the aqualung with fellow Frenchman Emile Gagnan.

Cousteau was involved in espionage activities for the French in World War II. He even won an award for stealing the Italian navy's code book; in fact, the Italian navy never even knew it was stolen. Hmmm, a French war hero. How rare!

It was during the war that Jacques Cousteau made his first underwater films and co-invented the aqualung in 1943. His interest in photography led him to co-invent an underwater camera that he called the "Calypso-Phot." He licensed it to Nikon.

If not for a fateful car accident at age 26, Jacques Cousteau would never have become an underwater explorer. In 1930, while he was a naval officer training to be a pilot, he was driving to a friend's wedding one night when his headlights went out, causing him to crash. The accident ended his flying days, and as a result he turned to the water.

There are a few other things that you might not have known about Jacques Cousteau...

  • He and wife Simone had two sons, and one of their grandchildren, Fabien Cousteau, carries on Jacques' legacy as a deep-sea explorer.

  • As Jacques Cousteau's wife, Simone Cousteau became the very first female scuba diver.

  • It was Simone's father who introduced Jacques Cousteau to his scuba co-inventor, Emile Gagnon.

  • Simone died in 1990, and seven months later Jacques married Francine Triplet, with whom he had a second family (a boy and a girl) while he was still married to Simone.

  • His aqualung was used to find and remove enemy mines after World War II.

It was nine years ago June 25 that Jacques Cousteau died, at the age of 87.
