This substance, made by Gerhardt in 1853, and reported on therapeutically by Kussmaul, of Strasbourg, in 1886, is derived from Anilin, to which it is chemically closely allied; it quickly came into use from its cheapness and its rapidity of action. A. Cahn and P. Hepp investigated its properties, and said "we would wish to term it Antifebrine."
