Edwin R. Manchester (1885-1954) was editor of DuPont Magazine for thirty years from December 1920 until his retirement in 1950. He joined the DuPont Company in 1918 on a special World War I assignment and became associate editor of DuPont Magazine in August 1919. Manchester's papers provide an indication of the role company magazines played in the advertising strategy of large companies in the first half of the twentieth century. The small collection primarily comprises office files from Manchester's decades as editor of DuPont Magazine within the Advertising Department, although there are a few publications from the Tippecanoe Securities Company, for which Manchester worked prior to joining DuPont.
