The United States Naval Academy provides an online naval academy graduate list. You must have an account to use the list. Once you sign in, you can find any graduate class by entering the class year.
To find further lists on alumni, you can contact the Association of Graduates at Annapolis. It has biographical information sheets on alumni. Searching through past registers of graduates can also be useful in finding lists of alumni. The Navy List is an official list that provides information on naval officers through the years. Records of the Bureau of Naval Personnel found at the U.S. National Archives and Records Administration provides extensive online information on Navy personnel.
Naval history museums, such as the Great Lakes Naval Museum, are also good places to search for alumni. Many genealogical sites, such as Genealogy.com, could also provide information on past graduates of the Naval Academy at Annapolis.
