General view of an unidentified employee preparing a water sample for testing at a Dearborn Chemical Company's laboratory facility in Chicago, Illinois. A stamp on the verso of the photograph for "The Fensholt Company," a public relations firm based in Chicago, suggests that the photograph was staged for advertising purposes. Founded in 1887, the Dearborn Chemical Company was a corporate ancestor of BetzDearborn, Incorporated best known for manufacturing water treatment chemicals for use in boilers and cooling towers.
