The year was 1856, and a makeshift laboratory stood inside an East London apartment.
Eighteen-year-old William Henry Perkin was attempting to synthesize quinine. Malaria was ravaging British soldiers and colonial administrators throughout the empire, while the only treatment came in small quantities from the bark of South American cinchona trees.
His mentor at the Royal College of Chemistry, August Wilhelm von Hofmann, had suggested that quinine might be synthesizable from coal tar, the foul-smelling waste product of the gas lighting industry.
Perkin tested aniline, a coal tar derivative, in his family apartment. The reaction produced nothing resembling quinine.
He obtained reddish-brown sludge.
But Perkin refused to pour the residue down the drain.
He added alcohol. He filtered the mixture, and the solution turned a brilliant purple.
Curious, he dipped a piece of silk into the liquid. It dyed the fabric a vivid, luminous mauve that did not wash out or fade in sunlight.
Purple dye was extraordinarily expensive, traditionally extracted from thousands of predatory sea snails through a laborious process dating back to the ancient Phoenicians.
Only royalty and the very wealthy could afford purple garments. Perkin recognized the commercial potential immediately.
He filed a patent in August 1856.
With financial support from his father and brother, he built a factory in Greenford, west of London, to manufacture mauveine. Queen Victoria wore a mauveine-dyed gown to the wedding of her daughter Princess Victoria in 1858.
Empress Eugenie of France declared mauve her favorite color. A mauve craze swept through European fashion, and Perkin's factory could barely keep up with demand.
Other chemists began investigating what else could be made from coal tar.
His discovery launched the synthetic organic chemistry industry, leading to an explosion of synthetic dyes, pharmaceuticals, perfumes, plastics, and explosives.
German chemical companies like BASF and Bayer built industrial empires on this foundation, and Perkin was knighted in 1906 on the fiftieth anniversary of his breakthrough.
He set out to synthesize medicine. He built an industry from sludge.
