Mr. Allen, in cockpit, flies it often and recently attained height of 1800 feet capable of making 63 mph." View full size.
August 1942. Republic Drill and Tool Co., Chicago. "Pioneers of the production line, these two young workers are among the first women ever to operate a centerless grinder, a machine requiring both the knowledge of precision measuring instruments, and considerable experience and skill in setting up. In this Midwest drill and tool plant, manned almost exclusively by women, centerless grinders have been efficiently operated by women for more than a year, and company production figures have continued to soar." Medium-format nitrate negative by Ann Rosener for the Office of War Information. View full size.
October 1942. State School of Mines in Golden, Colorado. "Speed in metallurgical analysis, to match the rapidity with which the nation arms itself, is possible through use of the spectrograph, a marvelous new machine used for study of materials through measurements of the arc of light they emit when heated. The aluminum and magnesium industries, steel companies and foundries use it for quick study of metals. Mines use it for exploration. The spectrograph will yield an analysis of seven elements in 15 minutes, which would require up to four hours by old chemical methods. Students in defense training courses at a famous mining-engineering school listen as an instructor shows them how the machine operates." Photo by Andreas Feininger, Office of War Information.
