THE SEVENTH SPECIAL AWARD 337 possible to substantiate the theory that emulsion stability is enhanced by high interfacial viscosity. He has found a similar correlation between foam stability and surface viscosity as measured by a "viscous-traction" surface viscometer which he has developed. Dr. Davies has presented a quantitative theory of emulsion type based on coalescence kinetics and has compared this with the Bancroft rule and the HLB system of determining emulsion type. In the field of olfaction Dr. Davies has advanced the theory that odorant molecules initiate the nervous impulse through dislocating or "puncturing" the cell membrane at the olfactory site and has evaluated the effect of molecular shape, size and adsorption on the olfactory threshold. The presentation was made at the Special Award Luncheon on May 12th at the Hotel Biltmore. William C. Griffin, Associate Director, Product Development, Chemical Division, Atlas Chemical Industries, Inc., acting as eulogist, described Dr. Davies' work. Dr. Sophie L. Plechner, president of the Society, in presenting the Award to Dr. Davies, gave the following citation: "John T. Davies, in recognition of your fundamental research in surface chemistry, your work in correlating emulsion stability with the viscosities of the monolayers at the oil-water interface, the development of a new theory of emulsion type and its relationship to the HLB factor, your studies of the olfactory threshold, I present to you, in behalf of the oF CosMETro CI•v. ms•ps this scroll and a check for $1000, with the hope that this Award will stimulate publications of research in those fields of science of particular importance to the cosmetic chemist." JOHN T. DAVIES, M.A. (CANTAB.), D.Sc. A EULOGY BY WILLIAM C. Gaivvi ]'HIS MAY, or may not be, a new approach for your eulogist to take, but I detest long after dinner introductions ... so, three weeks ago when I saw Warren Dennis and he voiced similar sentiments, we agreed that these might well be the shortest on record for this occasion. John Davies and I first met in 1956 when he attended a Gordon Research Conference, and while here, stopped by our laboratories to discuss surface active agents. In the past ten to fifteen years, John Davies has authored or co-authored ahnost fifty publications--an average of over three a year. And, in addi- tion, he is about to publish, co-authored with Sir Eric Rideal, a book Interfacial Phenomena.

338 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS Now this would not, in itself, be unusual--but the subjects of his publi- cations cover a wide range--they include: surface chemistry, colloidal systems, mass transfer stddies, biological processes, olfaction, reaction kinetics and philosophy. He is presently studying, among other things, the damping of waves and ripples, and the "stickiness" of cells. In these and other tasks, he has worked with many internationally known scientists--McBain, Schulman, Rideal, Klevens. Another facet of John's nature•organizational ability--was revealed to me at our second meeting when he was assisting at the presentation of the Second International Congress on Surface Active Agents. This organiza- tional ability is also a necessary ingredient in his present assignment ... Director of the Department of Chemical Engineering at the University of Birmingham. He has held this post only a few years so far, having been at Cambridge previously. You are all aware of Cambridge as a quiet, lovely, university town. John's comments on Birmingham are, "I might as well live in the U.S. We have to maintain two cars, and there's so much traffic you can't drive them !" John, though born in Great Britain, spent a decade in New Zealand. He was one of those fortunate persons who knew his goal while in high school. Later, he spent two years at Stanford and was married while there. However, being ever loyal to Britain, John married a British girl. They have two children, Brian and Christopher. John admits to having a few hobbies--mountaineering, swimming, sail- ing-and then says, "none serious." They no doubt cannot be with the demands of his family and, what must be an even greater self discipline, the demands of science. I am sure you will be interested to know that your award recipient will be the guest lecturer later this month at Stanford University in California. In a Society such as is represented here, there are many who labor behind the scenes in a wide variety of assignments. But, I'm sore, none has a more difficult job than the award panel ... trying to select the most qualified man in such a wide area of endeavor. I'm sure they have done well this year--and I'm honored to present--Dr. John Tasman Davies.
