Life

Liebermann first studied at the University of Heidelberg where Robert Wilhelm Bunsen was teaching. He then joined the group of Adolf von Baeyer at the University of Berlin where he received his Ph.D. in 1865.

Together with Carl Gräbe, Liebermann synthesized the orange-red dye alizarin in 1868. After his habilitation in 1870 he became professor at the University of Berlin after Adolf von Baeyer left for the University of Strasbourg. Shortly after Liebermann retired, in 1914, he died.

Work

In 1826, the French chemist Pierre Jean Robiquet had isolated from the root of a plant, madder, and defined the structure of, alizarin, a remarkable red dye. Liebermann's 1868 discovery that alizarin can be reduced to form anthracene, which is an abundant component in coal tar, opened the road for synthetic alizarin. The patent of Liebermann and Carl Gräbe for the synthesis of alizarin from anthracene was filed one day before the patent of William Henry Perkin. The synthesis is a chlorination or bromination of anthracene with a subsequent oxidation forming the alizarin.
