Digitized content includes a page from the November 1906 issue of the Journal of the Society of Dyers and Colourists and a foldout of an interleaved reflectance spectroscopy chart. The journal article excerpt includes an inset fabric sample dyed with "Perkin's Mauve," named for chemist William Henry Perkin (1838-1907). In 1856, when attempting to synthesize quinine, Perkin observed a bright purple residue. This residue turned out to be the first commercial aniline dye, marketed as Perkin's Mauve beginning in 1859. The sample pasted to this page was dyed by a small quantity of mauve supplied by Dr. Perkin himself and was intended to dispel confusion regarding the exact hue of Perkin's Mauve. The reflectance curve, dated 1954, compares the reflectance of a sample dyed with Mauve produced by Perkin in 1863 to a sample dyed with Mauve produced by August Merz in 1906.
