Women's Expanding Access to Scientific and Industrial Research Work in Early 1900s America

1910Best.-Nr. 231321910. Women in STEM Women's scientific and technical employment photo archive documenting female laboratory labor from the early twentieth century through the 1940s historically significant for showing how women entered academic industrial and commercial research settings in roles that ranged from student and aide to biologist technician and physician at a period when scientific work remained overwhelmingly male and women's access to professional authority was still sharply constrained. The group includes five press photographs and three non press photographs with women pictured not as incidental clerical staff but as active operators of instruments handlers of test animals readers of charts and participants in experimental procedure establishing direct visual evidence of women's expanding place within the infrastructure of American science industrial testing and laboratory employment. Photo archive of 8 silver gelatin photographs ranging from 3.5 x 5.5 to 8 x 10 inches various U.S. locations circa 1910 to 1940s. The archive spans classroom laboratory and industrial interiors. One 1910 photograph shows two men and one woman standing in a laboratory identified as "three scientists or science students" an early image of mixed gender scientific training. A 1937 press photo titled "aviation biologist works with hatchlings" shows Dr. Manisera in a lab coat hand feeding two week old canaries with a third bird perched on her head turning animal handling and experimental care into a public image of female scientific expertise. Another press photo shows Sally Wulff identified on the verso as an engineering aide with a science degree from the University of Iowa seated at a control bench calibrating experimental instruments at Wright Field. A 1938 non press image shows Dr. Marie D'Amour and Fred D'Amour studying a chart before a blackboard covered with formulas and technical notations linking the photograph to mammalian physiology research. A Hoboken New Jersey press photo depicts a female technician in the chemical division of the United States Testing Company operating a Fisher titrimeter "for performing volumetric analyses by electronic means" while a 1939 press photo from Newton Massachusetts shows a laboratory worker testing newly developed Permatron tubes used in high frequency welding and power transmission. Another press image captioned "A 'noise machine' used in experiments in the Colgate laboratory" shows a woman and man positioned on either side of the apparatus and a separate 1940s laboratory group photograph places a single woman among five men before a long demonstration bench and blackboard diagrams underscoring both women's presence and their numerical isolation within technical settings. Several versos retain typed caption slips editorial markings and reference stamps consistent with press photo circulation. Across the first half of the twentieth century women entered scientific work through normal schools universities wartime research demand industrial laboratories and auxiliary technical appointments yet their advancement was often channeled into subordinate or specialized designations even when their work required substantial training. This archive makes that structure visible through named and captioned examples of women conducting measurement instrument calibration physiological research electronics testing and experimental animal work across corporate academic and applied research environments. Minor residue on versos from former press labels or caption attachments; otherwise clean and well preserved. Overall very good condition. As a record of women's early technical labor the archive supplies concrete visual evidence of the pathways limits and visibility of women's participation in American scientific work before the full opening of postwar professional opportunity. unknown books
