Adolph Emmerling (13 June 1842, Freiburg im Breisgau – 17 March 1906, Baden-Baden) was a German chemist, known for his research in the field of agricultural chemistry.
He studied chemistry at the University of Freiburg, receiving his doctorate in 1865. Following graduation, he spent several years as a laboratory assistant in Freiburg and Heidelberg.[1] In 1870 he became director of the Landwirtschaftlichen Versuchsstation Kiel (Agricultural Experimental Station in Kiel), a post he maintained until his death. In 1874 he obtained his habilitation at the University of Kiel, and in 1882, received the title of professor.[2]
In 1869, with Adolf von Baeyer, he discovered a method for synthesizing indole by fusing ortho-nitrocinnamic acid with potash and iron filings ("Baeyer–Emmerling indole synthesis").[3][4]
