Joseph Georg Böhm was an Austrian astronomer, astrophysicist, cartographer, mathematician, and educator.
At the University of Prague, Böhm attended lectures in mathematics, physics, astronomy, and, after receiving his doctorate, became an assistant at the Vienna Observatory under Joseph Johann von Littrow. He then worked at the observatory at Othen and taught mathematics at the University of Salzburg. In 1839 he was appointed professor of mathematics and practical geometry at the University of Innsbruck, and in 1848 he was elected its rector. In 1852 Böhm was appointed director of the Prague Observatory and professor of theoretical and practical astronomy at the University of Prague.
Georg Böhm published several significant astronomical papers on solar observation. He is the creator of several instruments for astronomical measurements and observations, and he designed the Uranoscope and Universal Gnomon for amateur astronomical observations for the general public. As a member of the commission for the repair of the Prague Astronomical Clock, which he joined in 1865, he wrote a detailed description of it in the work Beschreibung der alterthümlichen Prager Rathausuhr. In addition to astronomy and its popularization, he was also involved in agriculture, economics, and geodesy. One of his important works is Ballistic Experiments (1865).
