In it and in other relevant journals, he published not only many of his chemical test results, but also socio-political issues that were related to problems of large-scale innovations in the field of chemistry. He also worked on chemistry manuals. In 1871 the Friedrich Wilhelms University in Berlin appointed him extraordinary professor for chemical technology. Also in 1871 he was appointed to the Technical Deputation for Trade in the Kingdom of Prussia . In 1873 he founded the first technological institute at a German university in Berlin and became its director.

After his retirement in 1921, he moved to Heidelberg.
