In 1856, eighteen-year-old chemist William Henry Perkin was working in his laboratory, trying to discover a way to synthesize quinine. After one of his experiments failed to produce anything but a useless reddish-brown sludge, he proceeded to clean his beaker with alcohol and when he did something amazing happened. When the alcohol combined with the sludge in turned into a vibrantly beautiful purple liquid. Perkin had accidentally discovered the world’s first synthetic dye. He named it mauveine.
At that time most colorful dyes were very expensive to produce and only the wealthy could afford the benefit of them. Dark blue, for example, was made from indigo, a subtropical plant that was one of the leading cash crops in slave-based economy of the American Deep South. At that time indigo was by weight more valuable than gold. Purple, so rare and valuable that it had always been considered the color of royalty, was laboriously produced from the excretions of certain kinds of mollusks. By comparison, the dye Perkin had discovered could be produced from coal tar, abundantly and cheaply available in industrial Britain. And whereas natural dyes tended to quickly fade, Perkin’s synthetic creations held their color.
After his serendipitous discovery, Perkin and two colleagues continued their dye research in secret, until Perkin was ready to register a patent and launch a dye-making business. Hoop skirts having come into style, more cloth than ever was required for women’s dresses, and fashionable colors were in great demand. Perkin’s discovery was well-timed. Within a few years Queen Victoria herself was wearing mauveine-dyed dresses, once outrageously expensive colors were now affordable by nearly all people, and Perkin was a wealthy man. He was only 18 years old when he registered his patent.
During his career Perkin invented synthetic dyes in numerous other colors. By the time of his death in 1907 at age 69, Perkin was an accomplished and highly esteemed scientist. The Perkin Medal, the highest honor in the U.S. chemical industry, is awarded each year to the chemist who has made the greatest contribution to the practical application of chemistry.
Sir William Henry Perkin was born in London on March 12, 1838, one hundred eighty-seven years ago today.
