Dear Dr. Moore,
Thank you for posting your request on History Hub!
Unfortunately, none of our TVA records are organized by employee number instead of by name. We also cannot determine which employee numbers are associated with what projects.
If you know the name, please request his or her Official Personnel File (OPF). OPFs and medical information for individuals who worked for the U.S. government in a civilian capacity prior to 1952 are in the custody of the National Archives at St. Louis, P.O. Box 38757, St. Louis, MO 63138. Please include the full name used during Federal employment, date of birth, Social Security Number (if applicable), name and location of employing Federal agency, beginning and ending dates of Federal Service. If there was any information you did not know, you could omit it or provide estimates, except for the name, which is required to search the records. For more information, the web site is https://www.archives.gov/st-louis/civilian-personnel.
If there is a particular relative or relatives of yours that you think this badge may have belonged to, you could submit requests under their names and see if anything records are located.
Please note that the National Archives and Records Administration (NARA) has suspended non-emergency reproduction and digitization services until further notice due to COVID-19. Orders will not be serviced until operations can resume safely. Once operations resume, document reproduction requests will be filled in the order in which they were received. We apologize for any inconvenience.
We hope this is helpful. Best of luck with your research!
Thank you very much for these helpful suggestions, Mr. Atkinson. There are only a couple of possible relatives who could be associated with the badge. I will make the inquiries you suggest when time permits.
