The story of the word

Paul Ehrlich named the white cells in the 1870s by what they were fond of, sorting them with his aniline dyes: basophils took up the basic stains, eosinophils the acidic eosin, neutrophils neither. It was classification by chemistry before anyone knew what the cells were for, and the names outlived the reasoning. Greek βάσις meant a step or a footing, from βαίνω, to walk, which is also how a chemical base got its name.
