Jacob Volhard (4 June 1834 – 14 January 1910) was the German chemist who discovered, together with his student Hugo Erdmann, the Volhard–Erdmann cyclization reaction. He was also responsible for the improvement of the Hell–Volhard–Zelinsky halogenation.

From 1852 to 1855 he studied chemistry at the University of Giessen, and afterwards, furthered his education at the University of Heidelberg. For two years he worked as an assistant under Justus von Liebig at the University of Munich, and in 1860/61 studied with August Wilhelm von Hofmann in London. In 1863 he obtained his habilitation at Munich, where he subsequently became an associate professor. In the meantime, he worked in the Institute of Plant Physiology at the Bavarian Academy of Sciences (1865–76). In 1879 he was named a professor of organic chemistry at the University of Erlangen, then in 1882 relocated to the University of Halle, where he served as a professor up until 1908.[https://books.google.com/books?id=0Y2aBQAAQBAJ&dq=%22Jacob+Volhard%22+1834&pg=PA67 Important Figures of Analytical Chemistry from Germany in Brief Biographies ...] by D.
