Auguste Antoine Piccard
(28 January 1884 – 24 March 1962) was a Swiss physicist, inventor and explorer, known for his record-breaking helium-filled balloon flights, with which he studied the Earth's upper atmosphere. Auguste was also known for his invention of the first bathyscaphe, FNRS-2, with which he made a number of unmanned dives in 1948 to explore the ocean's depths. Piccard's twin brother Jean Felix Piccard is also a notable figure in the annals of science and exploration, as are a number of their relatives, including Jacques Piccard, Bertrand Piccard, Jeannette Piccard and Don Piccard.
