during the war was able to supply very large quantities of cellulose acetate for airplane dope used to stiffen the cloth wings of the pianes. In 1913 the production of panchromatic plates and colored light filters was started, and in 1914 panchromatic motion picture film was placed on the market for the first time. This has met with great success and is used nut only for motion pictures in natural colors, but also to a considerable extent for the ordinary pictures. The company supplied plates especially adapted far X-ray purposes ior the first time in 1914, and thc sale of theesc increased very rapidly owing to the great growth of radiography. In 1918, a special X-ray filin was coated ou both sides with emulsion and marketed under the name of "Dupli-Tized" filrn. The use of this film is now general throughout the world, and the film has almost entirely replaced plates in radiographic work. Film far dental work, especially packed so that it could he used without requiring a darkroom. was placed on the market at an early date. The manufacture of X-ray intensifying screens was commenced in 1923. In I923 a complete system of amateur motion-picture photogrtphy was made available to the public. The apparatus comprised a camera, the Cine-Kodak, a projector, the Kodascopc, with the accessories, while the special film was supplied so packed that it could be loaded into the camera in daylight. This was intended for development by a reversal process which comerts the negative into positive, and thus makes the original film ai-ailable for projection. Owing to the small size of the film and the use of the reversal process, the taking of motion pictures by the general public, a t a practical price, was made possible. In 1925 a hand motion-picture camera, the Cin6Kodak Model R, driven by a spring, was introduced. The expansion of this sytem has been very rapid, and it seems possible that the introduction of amateur cinematography in 1923 will rank with that of portable hand camera photography in 1888. Throughout this development of the business of the company, and indeed of photography itself, the progress which has been realized has been due to the work of technical and scientific men, and each step, both in the development of new processes and in the introduction of improved manufacturing methods, lia'i involved a n immense amount of research and experiment. A laboratory was established in the earliest days. Onc of the
original buildiugs at Kodak Park was designed for use as a chemical laboratory and the direction of the manufacture of the company has always been in the hands of technical men. A t the present time three of the directors have heeu closely associated with Mr. &stman in his technical work from early days. W. G. Stuber, president of the company, joined the company ill 1893 as an experienced emulsion maker, and is still responsible for maintaining the photographic quality oi the sensitized products. F. W. Lovejoy, vice president and general manager, entered the coinpany in 1897 and later became manager of the Kodak Park Works. In 1906 he was appointed general manufacturing nianagcr. J. H. Haste, now manager of the Kodak Park Works, entered the compauy in 1897 and took charge of the chemical plant a t Kodak Park until he succeeded Mr. Lovejoy as manager of the plant. The original laboratory at Kodak Park was soon paralleled by other laboratories working specifically for various divisions of the factory, and it is now a practice for each department to establish a section which can supply it with the scientific information that i t may need for its direct control and operation. A research laboratory was established in 1912 to deal especially with the fundamentals of the science of photography and to carry on pure scientific research along all lines of interest to the company. In addition to its work in photography, the rescarch laboratory has established a department of synthetic chemistry to manufacture and supply the syntlictic organic chemicals required Tor research purposes in the United States, and this department has grown until a t the present time it supplies the greatest part of the chemicals required. C. E. Kenneth Mees has been the director of thc research laboratories since their formation, and has built up a staff of internationally Famous photographic experts on the various aspects of the theory

of photography. Nearly one hundred and fifty people are employed in the laboratory, a large percentage of whom are highly trained technical or scientific men. The Eastman Kodak Company is thus the example of ail industry created by a technical man and developed largely by technicians and chemists in which the scientific control of the work is fully developed and in which research pushing towards new achievements is "blazing the path."
