Auguste Piccard Auguste Antoine Piccard (28 January 1884 – 24 March 1962) was a Swiss physicist, inventor and explorer, known for his record-breaking hot air balloon flights, with which he studied Earth's upper atmosphere and cosmic rays, and 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.
Glenn Curtiss Glenn Hammond Curtiss (May 21, 1878 – July 23, 1930) was an American aviation pioneer and a founder of the U.S. aircraft industry. He began his career as a bicycle racer and builder before moving on to motorcycles. As early as 1904, he began to manufacture engines for airships. In 1908 Curtiss joined the Aerial Experiment Association (AEA), a pioneering research group, founded by Alexander Graham Bell at Beinn Bhreagh, Nova Scotia to build flying machines.
