He studied organic chemistry in Berlin as a pupil of Eilhard Mitscherlich, and in 1843 travelled to the University of Prague, where he studied under Josef Redtenbacher.{Statement based on translated text from an equivalent article at the German Wikipedia.[http://www.biographien.ac.at/oebl_9/13.pdf Redtenbacher Josef] @ Austrian Biographical Encyclopaedia 1815-1950 (ÖBL).
