"A Study of Some Reactions in Gels."

London:: Society of Chemical Industry, 1911., 1911. Series: Journal of the Society of Chemical Industry, no. 5, vol. XXX, March 15, 1911. 4to. pp. 256-257. 16 figs. on 3 plates. Original printed wrappers; creased. Very good. Complete issue of the Journal of the Society of Chemical Industry. Hatschek (d.1944) was known as a leading authority on colloid-chemistry. "EMIL HATSCHEK, who died in London on June 4, at the age of seventy-five, carried out pioneer work in many branches of colloid science and did much to direct attention in England to this subject. In spite of the stimulus supplied by the classical researches of Thomas Graham, little was being done in this country on colloids when, in 1911, Hatschek started a systematic course of lectures on colloidal chemistry at the Sir John Cass Institute. This was, I believe, the first regular course on the subject to be given in England, and it continued until 1935, when Hatschek reached the age limit for retirement. From about 1910 until 1932 Hatschek was producing original papers, all marked by elegance and strong individuality, which appeared in various periodicals, including the Proceedings of the Royal Society, the Transactions of the Faraday Society, Chemistry and Industry, the Biochemical Journal and the Transactions of the Institute of Mining and Metallurgy, apart from the twenty-six or so that appeared in the Kolloid-Zeitschrift. These names do something to indicate the width of interest of his work. His services to colloid science were acknowledged when he was made the guest of honour at the Colloid Symposium at Ottawa in 1932, a distinction much appreciated by him. His contribution at Ottawa was a paper on "The Study of Gels by Physical Methods", a subject to which he had devoted much attention." -- Obituary, by E. N. DA C.
