Don Walsh Career

Don Walsh was a distinguished oceanographer and former naval officer, who had a remarkable career marked by pioneering contributions to marine science and exploration.

Walsh was best known for his historic dive to the Challenger Deep, the deepest point in the Earth’s oceans, on January 23, 1960.

Alongside Swiss oceanographer Jacques Piccard, he descended to the Challenger Deep aboard the bathyscaphe Trieste, reaching a depth of about 35,798 feet (10,911 m) in the Mariana Trench.

This groundbreaking dive significantly advanced our understanding of the ocean’s depths.
