The plant was part of the 1937-1938 PHS industrial hygiene and engineering study of mercury exposure and its health effects in the hatmaking industry. The photo was published in USPHS Public Health Bulletin No. 263, Mercurialism and its Control in the Felt-Hat Industry, 1941, Figure 13. and captioned, “Giving the hat body its familiar shape.” Note that the worker’s hands are darkly discolored.|
The NIOSH Historic Photo Collection began as the “picture file” of the Industrial Hygiene Division of the U.S. Public Health Service (USPHS), c. 1930-1960. It is a unique collection of mid-20th Century images of American workers and workplaces and documents occupational safety and health research of that era. The collection consists of approximately 1,000 original photographs and schematic drawings.
