Abstract
ONE of the directors, of the Farbenfabriken vorm. Friedr. Bayer und Co., in Leverkusen, Dr. Christian Hess, died on July n in Bonn, after a serious operation. He was born January 14, 1859, at Eisenach, studied chemistry first at Jena and then in Berlin, where he worked for his doctorate under A. W. v. Hofmann in 1881. After having been assistant chemist to Prof. Wichelhaus at the Institute of Chemical Technology, he went in 1883 to the newly founded weaving, dyeing, and finishing school in Crefeld, where he developed very great activity as a teacher and an expert adviser. At that time he invented his process for removing iron from water. The large number of coal-tar dye-stuffs of a new character, which were discovered at that time, brought with them the necessity of using new methods for dyeing. This caused a lot of difficulties in the dyeworks, to meet which the dyemakers engaged colourists of good chemical training, able to introduce the new methods. One of the first of these was Dr. Hess, who was engaged by the Farbenfabriken in 1894.
