About Jacques Piccard

http://en.wikipedia.org/wiki/Jacques_Piccard

Jacques Piccard (28 July 1922 – 1 November 2008) was a Swiss oceanographer and engineer, known for having developed underwater vehicles for studying ocean currents. He and Lt. Don Walsh of the United States Navy were the first people to explore the deepest part of the world's ocean, and the deepest location on the surface of the Earth's crust, the Challenger Deep, in the Mariana Trench located in the western North Pacific Ocean.

Family life

Jacques Piccard was born in Brussels, Belgium to Auguste Piccard, who was himself an adventurer and engineer. Jacques' father Auguste twice beat the record for reaching the highest altitude in a balloon, during 1931–1932. The Piccard family thus has the unique distinction of breaking world records for both the highest flight and the deepest dive.

Jacques's father, who had already set altitude records in his balloon, started using the buoyancy technique used in balloons for developing a submersible vehicle, the bathyscaphe. Jacques initially started out his career by teaching economics at University of Geneva while continuing helping his father improve the bathyscaphe to demonstrate its potential for operating in deep waters. Together they built three bathyscaphes between 1948 and 1955, which reached record depths of 4,600 feet and 10,000 feet (the last one was bought by the government). With this success, the younger Piccard abandoned economics to collaborate with his father on further improving the bathyscaphe and demonstrating its practicality for exploration and research.

Jacques's son Bertrand Piccard is continuing his family traditions. He commanded the first nonstop balloon flight around the world in March 1998.

Challenger Deep mission

Jacques sought financial help from the U.S. Navy, which at that time was exploring various ways of designing submarines for underwater research. Jacques was welcomed to the U.S. to demonstrate his bathyscaphe, now named the Trieste. Impressed by his designs, the U.S. Navy bought the vessel and hired Piccard as a consultant. Recognizing the strategic value of a workable submersible for submarine salvage and rescue, the Navy began testing the Trieste for greater depths.

With his Trieste able to reach depths of 24,000 feet, Piccard and his colleagues planned on an even greater challenge—a voyage to the bottom of the sea. On 23 January 1960, Piccard and Lt. Don Walsh reached the floor of the Mariana Trench located in the western North Pacific Ocean. The depth of the descent was measured at 10,916 meters (35,813 feet); later, more accurate, measurements during 1995 found the Mariana Trench to be slightly less deep at 10,911 m (35,797 ft). The descent took almost five hours. The bathyscaphe carried no scientific equipment and no experiments were conducted; the mission's purpose was merely to prove that the depth could be reached. The descent progressed without incident until 30,000 feet, when the crew heard a loud crack. They continued the dive, however, finally touching down in "snuff-colored ooze" at 35,800 feet.

When they reached the featureless seabed, they saw a flat fish as well as a new type of shrimp. Marine biologists later disputed their observations, claiming that no fish could survive the 17,000 psi pressure at such depths. Upon discovering cracks in the viewing windows, Piccard cut the voyage short. After only a 20-minute stay on the bottom, they began dumping ballast for their return to the surface, and the damaged vessel returned to its escort ships without incident in three hours and 15 minutes.

The historic dive received worldwide attention, and Piccard wrote an account of it, Seven Miles Down, with Robert Deitz, a renowned geologist who had helped plan the mission. A planned return expedition, however, never occurred. The Trieste was expensive to maintain and operate. It was incapable of collecting samples and could not take photographs and so had little scientific data to show for its voyages. The original vessel was retired in 1961, although a rebuilt version later located the remains of two lost U.S. Navy nuclear submarines, the Thresher and the Scorpion.

Ben Franklin mission

On 14 July 1969, just two days before the Apollo 11 launch, the Ben Franklin, also known as the Grumman/Piccard PX-15 mesoscaphe, was towed to the high-velocity center of the Gulf Stream off the coast of Palm Beach, Florida. Once on site, the Ben Franklin with its six-man, international crew descended to 1,000 feet off of Riviera Beach, Florida and drifted 1,444 miles north with the current for more than four weeks, surfacing near Maine.

A crew of six was chosen. Jacques Piccard was the mission leader; Erwin Aebersold, another Swiss, was Piccard’s handpicked pilot and main assistant to Piccard and project engineer during the Franklin's design and construction. Grumman selected a Navy submariner named Don Kazimir to be captain. The U.S. Navy Oceanographic Office sent Frank Busby to conduct a bottom survey along the drift track over the Continental Shelf and the Royal Navy sent Ken Haigh, an acoustic specialist, who studied underwater acoustics and performed sonic experiments up and down the water column throughout the mission. The sixth man was Chet May from NASA. His specialty was "man working in space". Wernher von Braun learned about the Franklin mission, visited the submarine in Palm Beach, and considered the mission a kind of analogue to a prolonged mission in space, such as on the forthcoming Skylab. He appointed May as a NASA observer to accompany the mission and study the effects of prolonged isolation on the human crew. Named for the American patriot and inventor who was one of the first to chart the Gulf Stream, the 50-foot Ben Franklin was built between 1966 and 1968 in Switzerland for Piccard and the Grumman Aircraft Engineering Corporation. It has been restored and now resides in the Vancouver Maritime Museum in Vancouver, Canada.

Influence and distinctions

Ambient artists Mathieu Ruhlmann and Celer collaboratively released an album called Mesoscaphe in 2008, dedicated to the voyage of the Ben Franklin.

He was awarded the Howard N. Potts Medal in 1972.

On 1 February 2008, Piccard was honored Doctor honoris causa at the Catholic University of Louvain (Louvain-la-Neuve).

Other activities

Piccard was the founder of the Foundation for the Study and Protection of Seas and Lakes, based in Cully, Switzerland.

Jacques Piccard constructed four submarines and applied for at least one US patent (D200,506) for a submarine:
