The Trieste is Professor Auguste Piccard’s newest “bathyscaphe.”* On the surface she looks vaguely like a ship, but she is really an underwater balloon designed to sail the depths of the sea ...

Auguste Piccard, now aided by his son Jacques, took what he had learned to design and build a third bathyscaphe, the Trieste, named after the city where it was constructed.

The Trieste was the creation of Auguste Piccard, a Swiss physicist who invented a pressurized aluminum gondola that set a balloon altitude record of 51,775 feet in 1931.

Such a project resonated with his family’s history. His grandfather, Auguste Piccard, was a physics professor-turned-inventor who built the first pressurized aluminum gondola.

The bathyscaph was a deep submergence vehicle, or DSV, invented by Swiss physicist Auguste Piccard. It was no ordinary submarine. In fact, Trieste had been further described as a deep-diving ...

The bathyscaph Trieste dive to the deepest point in the world's oceans would've been impossible without financial support of the Office of Naval Research.

Auguste Piccard's great bathyscaphe, the Trieste, made several descents in the Atlantic Ocean, but its greatest moment came after it was acquired and redesigned by the U.S. Navy.

Piccard designed and built Trieste with his father, Auguste, who was a notable engineer that had twice held the record for the highest manned balloon flight.

In 1960, USN Capt. Don Walsh and Jacques Piccard took bathyscaphe Trieste to the bottom of the Mariana Trench, the lowest point on Earth. At 91, Walsh recalls the record-setting mission.

Mme. Auguste Piccard put her foot down. Middle-aged professors, she declared, especially her husband, should not risk their lives year after year making record-breaking balloon flights into the ...
