Prize share: 1/1
A new industrial branch developed in the late 1800s, dye manufacturing. Beginning in the 1860s, Adolf von Baeyer performed a series of studies on the chemistry of dyes. These led to the production of several dyes from coal tar. The most important of these was the blue dye indigo, which, thanks to von Baeyer, could now be produced industrially instead of being extracted from plants. This made it much less expensive to produce. Another group of dyes Adolf von Baeyer studied were phthaleins.
