The People series consists primarily of individual portraits of executives, as well as group portraits of the board of directors and executive and finance committees. There are a few portraits of significant scientists and employee group portraits. The images included in this series place primary subject or focus on the portrait sitter (images of people in the Plant sites series feature the plant site as the subject, with employees shown outside the building or working inside it). The images are photographic prints and negatives; in most cases, the negative matches the print or contact sheet. Slides are unique images. The bulk of the materials dates from 1949 to 1998, with a few items dating between 1903 and 1946 and a few to the 2000s. The series is arranged in alphabetical order by the individual's last name or group name.
