Human beings have always set out to expand the limits of our knowledge and experience of the world. We want to challenge ourselves and see how far we can go, and we want to discover things that are beyond the normal reach. And so, almost 60 years ago, two men set out to be the first people to dive toward the deepest point of the ocean.
On 23 January 1960, two men clambered aboard the Trieste for its attempt to dive into the Challenger Deep of the Mariana Trench: marine specialist Lieutenant Don Walsh of the US Navy; and oceanographer Jacques Piccard, son of the vehicle’s inventor.
