General view of Dearborn Chemical Company employee E.P. Fager preparing a water sample for testing. 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.
