Dear Mr. Davis,
We suggest that you request a copy of his/her Official Personnel File (OPF). OPFs and medical information for individuals who worked for the U.S. government in a civilian capacity before 1952 are in the custody of the National Archives at St. Louis (RL-SL). Please email RL-SL via email at email@example.com and include the full name used during Federal employment, date of birth, Social Security Number (if applicable), name and location of the employing Federal agency, beginning and ending dates of Federal Service. For more information, please check the Official Personnel Folders (OPF), Archival Holdings and Access website.
Due to the COVID-19 pandemic, the Civilian Personnel Records Center (CPR) in Valmeyer, IL still will maintain minimal staffing levels to support emergency reference requests only. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
