The ability to stain bacteria hinges on having dyes that could reliably bind to cellular components and provide clear contrast under a light microscope. This capability blossomed with the rise of synthetic aniline dyes from coal tar chemistry in the mid-1800s. When William Henry Perkin discovered mauveine in 1856, it demonstrated that dyes could be produced cheaply and in a wide range of colors, spurring a whole industry of aniline dyes. These dyes offered the durability and variety microbiologists needed to color bacteria, making them visible and more easily studied. By the 1880s, staining techniques became standard tools in microbiology, culminating in methods like Gram staining that further enhanced visualization. Because these developments occurred in the 19th century, that is the period when the production of aniline dyes enabled staining bacteria.
