Swiss-born Belgian physicist and balloon and undersea explorer.
He studied and taught physics in Zürich and later at the University of Brussels (1922–54). In 1930 he designed a balloon with an airtight, pressurized cabin to ascend into the stratosphere to study cosmic rays. In 1932 he ascended over 55,500 ft (16,650 m). The undersea bathyscaphe he designed with his son, Jacques (b. 1922), descended in 1953 more than 10,000 ft (3,000 m). His grandson Bernard Piccard made the first round-the-world balloon flight in 1999.
