As a new
understanding of the chemical nature of dyes began to emerge,
the attention of the scientific community in the early decades
of the nineteenth century began to be focused on isolating
the coloring matters in dyes in an effort to reproduce them
artificially in laboratories. The
research was still largely empirical and advanced through
trial-and-error. Even
with the 1856 discovery of the aniline dye, mauveine -- a
compound that did not exist in nature -- theoretical understanding
came after the fact and the discovery was purely accidental.(1)
Among
the earliest discoveries that would initiate the progressively
artificial ways to process natural dyestuffs was the isolation
in 1820 or 1827 (2) of alizarin, the compound in the madder
root that produces the color red. Extracted
through complex chemical processes, the first attempt at alizarin's
chemical formulation was not proposed until 1850 (3) and its
true synthesis did not occur until 1868. Other
natural products such as coal were at the source of great
advancements in the field of chemistry and color. Used
to light lamps and for heating as early as 1805, coal gas
gained popularity during the 1830s and caused many chemists
to ponder as to the potential usefulness of its tarry residue.(4) As
luck would have it, an eighteen-year-old working in his parents'
garden shed would soon stumbled across a reddish-brown sludge
extracted from a coal-tar product that would cause a fashion
phenomenon.
William
Perkin was a gifted young student of August Wilhelm Hofmann,
the first director of the Royal College of Chemistry in London
where, starting in 1845, many young pupils were mentored in
the mysteries of coal-tar hydrocarbons.(5) Although
Perkin would become famous in 1856 for his mauveine aniline
dye, it was Frédéric Crace Calvert, educated
in France and appointed as a professor of Chemistry at the
Royal Institution in Manchester in 1846 that cracked the code
to create the first purple and red aniline dyes in 1854.(6) Unlike
Crace Calvert, Perkin saw potential in the reddish-brown sludge
he obtained while attempting to produce synthetic quinine
at Hofmann's suggestion.(7) In
1856 the Perkin family launched a factory which had to compete
with other producers of semi-synthetic purple dyes, namely
murexide, commercialized in 1853 and synthesized from the
uric acid of solidified droppings of the Peruvian guano bird
(8), and French Purple, processed from lichens in 1856 (9)
and known as mauve in France -- a term used by Perkins
to secure a French connection to his product and thus a link
to the world of fashion.(10)
Perkins
worked relentlessly to solve the problems of aniline dyes
and make them commercially viable. The
first problem was the dye's lack of solidity on fibers other
than silk, namely cotton and wool, the former being solved
by mordanting procedures found in 1857.(11) The
second problem was costs: as aniline required a multistep
synthesis, it was an expensive substance to produce on an
industrial scale.(12) Perkins
found processing shortcuts through the use of benzene, which
was cheap yet hazardous and in need of further refining. (BE,
213) By
the late 1850s and 1860s, mauve became the indisputable color
of high fashion and Perkin overtook his competitors.(13)
Other
aniline colors soon followed that caused tidal waves in fashion. 1859
saw the arrival of François-Emmanuel Verguin's fuchsine
and Edward Chambers Nicholson's roseine, known soon
after as magenta.(14) By
1860, the recipe for magenta was accidentally altered by Charles
Girard and Georges de Laire to produce aniline blue.(15)
Hofmann contributed aniline violet in 1863, thus infiltrating
Perkin's market.(16)
