PICCARD Auguste (1884-1962) physicien suisse.
L.A.S. "A. Piccard", Chexbres (Switzerland) 2. VIII. 1956, to M. AUBRY, Administrator-Director of Belgium-Télé-Programmes| 1 page and a quarter in-4.
About his stratospheric flights.
He is touched by his proposal and communicates the requested information to him: " the first ascent of the F. N. R. S. took place on 27.V.31 in Augsburg. The gondola, or rather the watertight cabin (pressurized) used that day by Mr. Kipfer and me is located at the university of
Brussels. It is the first airtight (pressurized) cabin that was used in aeronautics. When I asked for a loan from the Belgian National Fund for Scientific Research, I specified that it was to show aircraft manufacturers that it was possible to travel in the stratosphere.
The altitude determined by me by reading the mercury barometer was 15,946 m. It was approved, on the faith of the barogram, by the F.A.I.
for 15 781 m. It is known that this ascent presented difficulties and that it did not give all the desired results. The second ascent took place in Dübendorf (Switzerland) on 18.VIII.32. The barometric pressure reached was 73 mm of mercury. The F.A.I. calculated and approved the altitude at 16 201 m while the Swiss Topographic Service calculated the altitude on the basis of direct trigonometric measurements at 16 940 m. "...
