Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.
Vintage photos of:
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.
