Otto H. Hahn died at Jena on July 26th, 1915, aged 70 years.
He was born at Appolta in Thuringia, and graduated from the Bergakademie at Clausthal in the Harz; and he also studied at the University of Jena. He went to the United States in 1863, and, after spending a short time in New York, went westward to California, where he became associated with C.A. Stetefeldt.
He was at Eureka, Nevada, in 1870, soon after the discovery of the great silver-lead deposits; and he remained there for several years, engaged in silver-lead smelting, in which branch of metallurgy he came to he regarded as one of the chief authorities.
Mr. Hahn retired from active practice about ten years before his death and resided at Jena, in Germany. He made several important contributions to the literature of silver-lead smelting, among them being a paper read before the Institution in 1900, entitled ‘The Development of Silver Smelting in Mexico.’
Mr. Hahn was elected a Member of the Institution in 1898.
