Astronomer(with The Mice galaxies)

Pride is of the highest importanc2e as a buisi-ness motivator. We are prouLd that A. G.Millikan, a Kodak emulsion researcher, hassufficient standing in his own right as anastronomer to be granted telescope time at amajor observatory. We are pained that theadmirable accomplishments of radio astrono-my, x-ray astronomy, and infrared astronomVcan sometimes leave a nonparticipating ob-server of the scientific scene thinking thatthe photographic emnuilsion has heen dropped from the toolkit. Heavens, no' Heaxvenlv endeav or wx ithoLut it woulldC hetotugh indeed.

To hrcacien wid/c/erstanidi/g' of Its prese/it r(ole in astro/o)m/vi,Alillikan lia.s w'rittc'/c an article "Inaic l) tec tio/i at ti' TeleCsCopc" i/i American Scientist forI Acay-/cc, 1974. Wt li,/lc/l bcproud to 1i as,kec/ fOi ci rcepriitat(lt) pt. 5 5V, Kcodak Roc lc stcrN. 4Y. 14050.

Astroniomiiers don't need adv ertising to renmitncd them thatthe,v need the photographic emlUlsion. They can iiiidcistandthat there are no htic stakes to be won in plates and filmiis tortheir uise, We persist for 1) Kociak tradition and pride, 2 ) adesire to clo something tiseftil for Science, which has done alot for US, 3 ) awareness of how much such merchandise as

tb.e gentleanan below promotes owes to sensitizing-dye tech-nology btiilt tip vears ago to solve purels astronomical prob-lenms.

If Kodak products for astronomy dotn't need advertising,perhaps certain Kodak films that offer the advantage of] com-

plete insensitivity throughout the electromagnetic spectrLtido need advertising. They are manufactured in France withdyed celltilose nitrate in place of an emulsion.
