X-Rays.

New York:: James Picker, 1919., 1919. 21.5 cm. 48 pp. 10 figures, 15 accessories shown. Tan printed wrappers; creased (bi-folded). Very good. Rare pioneering price-list catalogue of x-ray tubes and apparatuses by the first marketer of x-ray equipment. In 1896, one year after the discovery of x-rays, George Eastman entered into an agreement to supply paper and plates for the process. Kodak granted James Picker (1882-1963) an agent for plates in 1909 and Picker introduced the first printed price list for X-ray accessories in 1915. By 1919 double-emulsion films replaced the glass plates but were highly flammable. Picker was instrumental in convincing Kodak by 1930 to produce safety films. Picker X-Ray Corporation was sole proprietor of the 390 lb. U.S. Army field X-ray unit during W.W.II. Dr. C. E.(Charles Edward) Kenneth Mees (1882-1960) was hired by Kodak in 1912 to organize and head the research laboratory in Rochester. See: trevorwright.
