How High/Low Can You Go? - The Explorer Auguste Piccard

Scientists and explorers we are...to boldly go where no man has gone before. If there is one scientist, who might serve as the prototype of an bold explorer, then we have to consider Auguste Piccard, a Swiss professor of physics, who tried to explore the deepest depths of the sea as well as the extreme stratosphere of the earth. And he did this not only in theory, but by experiment (always including his own person).

Born in 1884 in Basel, Switzerland, he graduated in engineering at the Polytechnikum Zürich in 1910. After world war I in 1917 he discovered a new Uran isotope Actinuran (today referred to as Uran 235). In 1922, Piccard was appointed professor of physics at the Polytechnic School of Brussels, where he tried first test flights of stratospheric free balloons. With the help of one of his balloon experiments he was able to give an experimental proof of Albert Einstein's theory of relativity.

In 1930, his curiosity about the upper atmosphere and his interest in ballooning led him to design a spherical, pressurized aluminum gondola that would allow ascent to great altitude without requiring a pressure suit. On 27 May 1931, Auguste Piccard and Paul Kipfer took off from Augsburg, Germany, and reached a record altitude of 15,785 m. During this flight, Piccard was able to gather substantial data on the upper atmosphere, as well as measure cosmic rays. On 18 August 1932, launched from Dübendorf, Switzerland, Piccard and Max Cosyns made a second record-breaking ascent to 16,200 m . He ultimately made a total of twenty-seven balloon flights, setting a final record of 23,000 m (75,459 ft). By reaching the upper atmosphere, Auguste Piccard might also be referred toa s the very first astronaut.

In the mid-1930s, Piccard's interests shifted when he realized that a modification of his high altitude balloon cockpit would allow descent into the deep ocean. Following the same principle as his pressurized balloon gondola, in 1937 he constructed a deep sea diving vehicle, called the Bathyscaphe, a small steel gondola built to withstand great external pressure. Work started in 1937 but was interrupted by World War II. The deep-diving submarine finally was finished in 1948. It made a number of unmanned dives in 1948 before being given to the French Navy in 1950. Together with his son Jacques, Auguste Piccard undertook a redesign of the Bathyscape and in September 30, 1953 both set a dive record with 3150 meters depth at Ponza in the Tyrrhenian Sea. On 23 January 1960, Jacques Piccard together with US Navy Lt. Don Walsh reached the floor of the Mariana Trench located in the western North Pacific Ocean with the Bathyscape Trieste. The depth of the descent was measured at 10,916 meters (35,813 feet).

As a mater of fact there are several references of Prof. Auguste Piccard in popular media. He was the inspiration for Professor Cuthbert Calculus in The Adventures of Tintin by Belgian cartoonist Hergé. And also the name of Start Trek - Next Generation Captain Jean-Luc Picard stems from Auguste Piccard.

Here, you can watch some rare footage from Italian Archive Cinematografico Luce of Auguste Piccard after the descend near the city of Desenzano of his record flight from 1932.
