Abel.” $450 First Edition, Offprint Issue. Abel and Davis conducted the first detailed analysis of the chemical composition of black skin pigment (mela- nin). They concluded that “In the present state of our knowledge we can only say that it seems highly probable that the pigment of the negro’s hair is not different from the dark pigment found in the hair of the white races, and we may infer that the pigment of the black skin differs only in amount and not in kind from that deposited in the skin of the white man” (p. 40). Abel founded the department of pharmacology at Johns Hopkins and made a number of important discoveries during his long tenure there, including the isolation of epinephrin and the crystallization of insulin.
