Johann Caspar Horner

Johann Caspar Horner (1734–1834), was a Swiss physicist and astronomer.

In 1805 Johann Caspar Horner visited Japan with the Prussian Georg Heinrich von Langsdorff, as a scientist to the Kruzenshtern mission that also brought the Russian ambassador Nikolai Rezanov to Japan.

Horner made a hot air balloon out of Japanese paper (washi), and made a demonstration in front of about 30 Japanese delegates. [Ivan Federovich Kruzenshtern. “Voyage round the world in the years 1803, 1804, 1805 and 1806, on orders of his Imperial Majesty Alexander the First, on the vessels Nadezhda and Neva”.] [Polak 2005, p.78] This followed the first flight of a hot air balloon by the brothers Montgolfier in France in 1783.
