The discovery of aniline and the origin of the term “aniline dye”

Abstract

An historical background is provided for the term, “aniline dye,” which is still widely used as a synonym for “synthetic dye.” The discovery of aniline and the role of Hofmann in clarifying it are described. The subsequent discovery of mauveine (mauve) by a student of Hofmann's, William Perkin, and his difficulties in transforming an academic synthesis into a commercial product also are discussed. The key role of Scottish dyers, the Pullars of Perth and Thomas Keith in London, in this technology transfer is described. The subsequent ascendancy of the German dyestuff industry over British manufacturers is noted.
