Ehrlichs Early Colorful Work with Histological Staining

Flemming s tentative term for the cell material that takes up dyes, chromatin, was enlarged upon by Wilhelm von Waldeyer-Hartz (1841-1923) who, in 1888, called the threadlike structures in the nucleus chromosomes, or colored bodies. Thus our present-day vocabulary with which we describe cellular components had its origin in color reactions, and remains a colorful reminder of that colorful past.
