Jean-Felix PiccardBorn 28 Jan 1884; died 28 Jan 1963 at age 79.Swiss-American chemical engineer and balloonist who conducted stratospheric flights for the purpose of cosmic-ray research. His first balloon ascent (1913) was with his twin brother, Auguste Piccard. With his wife, on 23 Oct 1934, he made the first successful stratosphere flight through clouds, ascending to a height of 11 miles (18 km). In 1936, Piccard flew the first successful plastic film balloon, which he invented and developed, the precursor of the plastic film balloon for high altitude experiments still used for scientific purposes. In 1937, he made an ascent of 11,000 feet (3,350 m) to test a metal gondola attached to a cluster of 98 balloons. He also developed a frost-resistant window for balloon gondolas and an electronic system for emptying ballast bags. |
