Joseph Jtner (1775-1848) was the first successful Austrian globe-maker in an otherwise largely undistinguished national industry. A captain in the Austrian army, having worked on a number of military maps, he collaborated in 1822 with Lieutenant Franz Lettany (1793-1863) to produce his first 1-foot diameter terrestrial globe. The companion celestial globe, in which Lettany had no hand, was produced in 1824 and like this armillary sphere, showed the stars calculated for the year 1850, which would fall two years after his death. Working from Prague, however, his initial success was no match for the soon-to-be pervasive influence of the most prolific of Czech manufacturers, publishers to the Austro-Hungarian monarchy, Jan Felkl and Son.
