He was educated at a Realgymnasium at Mannheim and after the age of 15 at the technical school of Karlsruhe, proceeding to the university of Heidelberg, where he graduated as doctor of philosophy (1863). From 1863 to 1867 he first studied organic chemistry under A. Kekule at Ghent, then visited England, studied in Paris and with Ch. Friedel and Wurtz, and returned to teach at Heidelberg. In 1873 he went to Kiel as professor of chemistry and director of the laboratory, remaining there until 1889 when he went to the university of Breslau in the same capacity. He was made an honorary member of the Pharmaceutical Society of Great Britain in 1886 and received the Hanbury medal for original research in chemistry in 1889. Details of his work, especially in connexion with benzene derivatives, are given in 6.53, 55 and 942; 11.215; 20.430; 25.892 and 21.635. He published Entwicklungsgeschichte der Chemie von Lavoisier bis zur Gegenwart (1868) and other works on chemistry, collaborated in a Handwörterbuch der Chemie (13 vols., 1882-96), and wrote a volume of reminiscences, Lebenserinnerungen (1912).
