Biography

From 1839 to 1843 he studied law at the University of Vienna, where he also attended lectures given by mathematician Joseph Petzval, physicist Andreas von Ettingshausen and astronomer Joseph Johann Littrow. After graduation, he worked as an assistant at observatories in Vienna (1843–47) and Prague (1847–52). In 1852 he was named a professor of mathematics at the Polytechnic Institute in Prague, and in 1863, succeeded Karl Kreil as director of the Centralanstalt für Meteorologie und Erdmagnetismus (Central Institute for Meteorology and Geomagnetism) in Vienna. From 1863, he also served as a professor of physics at the University of Vienna.^[1][2]

In 1865 he founded the Österreichische Gesellschaft für Meteorologie (Austrian Society of Meteorology), of which, with Julius von Hann, he was editor of the organization's Zeitschrift (magazine).^[1][3]
