Sheck Exley: The Greatest Cave Diver Who Ever Lived

History of Everything

Show Notes

Sheck Exley didn't just push the limits of human exploration—he redefined them. Today we dive into the life of the man widely regarded as the greatest cave diver who ever lived.

From his first cave dive at age 16 to his record-breaking descent past 800 feet into Mexico's El Zacatón, Exley spent three decades exploring the most dangerous underwater caves on Earth. Along the way, he developed the techniques, equipment, and safety protocols that made modern technical diving possible.

But his obsession with the depths would ultimately cost him everything. On April 6, 1994, Exley attempted to reach the bottom of the world's deepest underwater sinkhole—a dive from which he would never return.

In 1975, a French mercenary named Bob Denard landed on the beaches of the Comoros Islands with a handful of men and changed the course of African history. Then he did it again. And again. And one more time for good measure. This is the story of how one man overthrew the same government four separate times, ruled an island nation as a puppet master for over a decade, and somehow died peacefully in France instead of prison.
