Henry Earle Lumpkin Photograph Collection

11 items

This collection, digitized here in its entirety, consists of photographs associated with the use of mass spectrometry at the Humble Oil and Refining Company and Exxon laboratories located in Baytown, Texas. Dating from the 1960s and 1970s, the photographs were collected by Henry Earle Lumpkin, a research chemist at the companies. Of particular note are several photographs of the Mass Spectrometer 9 (MS-9), the first of its kind installed in the United States. Several group portraits and a photograph from an award ceremony honoring Mr. Lumpkin's service to Humble-Esso, later Exxon, round out the collection.
