This 1950s historical photograph was provided by the Center for Disease Control and Prevention's (CDC), National Institute for Occupational Safety and Health (NIOSH). The image depicted an industrial plant physician and nurse, as they were examining a plant worker. The doctor was using a stethoscope in order to auscultate the patient’s chest sounds emanating from within the worker’s chest cavity. The nurse was preparing to measure the worker’s blood pressure, using a device known as a sphygmomanometer.
The NIOSH Historic Photo Collection from which this photograph was derived, began as the Picture File of the Industrial Hygiene Division of the 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.
