![]() The Trieste was retired in 1961.Īfter the success of the Challenger Deep mission, Piccard and his father designed a new submersible called a mesoscaphe. The dive was a success for bragging rights, but had little scientific impact since it was incapable of taking samples or taking photographs. Piccard wrote about the adventure in Seven Miles Down with the help of Robert Dietz, a geologist who had helped to plan the mission. ![]() The historic dive captured the imagination of the world. The journey back to the surface took a little over three hours. After a 20-minute stay, the Trieste dumped its ballast. This discovery shocked the scientific community because scientists were convinced that no life could survive the intense pressure this deep in the ocean. At this incredible depth, they observed fish and shrimp. They descended for nearly five hours and reached a depth of 35,797 feet (10,911 meters). Their goal was the Challenger Deep, the deepest known place in the world. Don Walsh took the Trieste to the Mariana Trench in the Pacific Ocean. But Piccard was planning a much more daring dive which would be a literal voyage to the bottom of the sea. At this time the Trieste was capable of reaching depths of up to 24,000 feet (7,315 meters). They purchased the Trieste and hired Piccard as a consultant. They were impressed with the design and saw its potential for underwater salvage and rescue missions. Piccard demonstrated the capabilities of the bathyscaphe to the Navy. Navy was working on submarine designs for underwater research. ![]() In 1956 Jacques Piccard went to the United States to seek funding for further research. With the successes of the bathyscaphe, Jacques gave up teaching to continue working with his father on improving the vehicle and demonstrating its uses for exploration and research. In 1953 they tested a new vehicle called the Trieste and reached a depth 10,168 feet (3,099 meters) in the Mediterranean near Capri off the coast of Italy. They built three bathyscaphes between 19. Jacques worked with his father to improve the bathyscaphe design and prove its potential for deep water dives. His father was using the buoyancy technique from balloons to develop a deep-sea submersible vehicle known as a bathyscaphe. In 1946 he received his licentiate degree and in 1946 and began teaching. He took a year off in 1944 to serve with the French First Army. He graduated in 1943 and went to college at the University of Geneva, where he studied physics and economics. Jacques attended school at a private school called École Nouvelle de Suisse Romande in Lausanne, Switzerland. His father, Auguste Piccard, was an adventurer who had set two records for reaching the highest altitude in a balloon in 19. Jacques Piccard was a Swiss oceanographer and engineer.
