Otokar Theodor Arno Ritter von Bradsky-Laboun (written variously), (1866-1902) was a German aviation pioneer and Diplomat (Herald) to Japan and India.[1] Our data suggests he lived also in France and/or Switzerland.
He came from the old Czech noble family Bradský von Labouň associated with the village of Labouň near Jičín (Jitschin) in East Bohemia.[1]
He constructed a steerable balloon with engineer Paul Morin. The balloon was made by Henri Lachambre. The gondola was 17 m long and weighed 350 kg. It was attached to 16 steel cables. The propeller had a diameter of 4 m; the engine turned it at 350 rpm.[4] The first flight took place on October 13, 1902, from Vaugirard. Around 9 o'clock they were over Stains and wanted to land at Ly. De Bradsky and Morin perished when the nacelle ripped off about 500 feet (180 m) up.[1]
