Reports, scrapbooks, photographs, equipment descriptions and diagrams, and notes regarding the organization of the Poulsen Wireless Telephone and Telegraph Company and subsequently, Federal Telegraph Company. Much of this material was collected by early company electrical technician Douglas M. Perham, and includes many items given to him by fellow Federal Telegraph Company employees such as Leonard Fuller, Cyril F. Elwell, and Harold F. Elliott.

Douglas M. Perham (1885-1967) was an early wireless experimenter and radio broadcaster, and a talented technician and craftsman. In 1909, Cyril Elwell rented Perham's Palo Alto bungalow to serve as Poulsen/Federal's first laboratory, hiring Doug as the first American employee of Poulsen Wireless. Over the next two decades he worked, on and off, with many of Federal's notable personalities. He also took part in early installations in Stockton, San Francisco, Southern California and Texas, 1910-1919.
