Don Walsh

The Voyage

On 23 January 1960, U.S. Navy Lieutenant Don Walsh and Swiss engineer Jacques Piccard descended into the Mariana Trench aboard the bathyscaphe Trieste, reaching the floor of Challenger Deep — 10,916 metres down. The dive took four hours and forty-eight minutes; they spent only twenty minutes on the bottom because the implosion of an outer porthole on the way down had cracked their viewing arrangement. No one returned to Challenger Deep for fifty-two years. Walsh went on to a long career in oceanography, founding the University of Southern California's Institute for Marine and Coastal Studies and serving as president of the Marine Technology Society.

The Stewardship

Walsh spent the last sixty years of his life advocating for sustained civilian access to the deep ocean. He served on the boards of the Explorers Club, the Marine Technology Society and many oceanographic foundations, and was a vocal critic of the underinvestment in ocean science compared with space science. He was on the support team for James Cameron's 2012 dive and for Victor Vescovo's 2019 Five Deeps Expedition — physically present on the support vessel both times, fifty-nine years after his own descent.

Bathyscaphe Trieste — Auguste Piccard's deep-submergence design, U.S. Navy-operated 1958–1966. The Trieste is preserved at the National Museum of the United States Navy in Washington, D.C.

Why this voice on Wind Voyage

Walsh is the founding voice of civilian deep-ocean access — the man who proved, with one dive, that the deepest place on the planet was reachable. Wind Voyage owes the same intellectual debt every modern ocean programme owes him: that the sea is reachable if you build for it.
