A scholar who helped introduce well-documented studies in U.S. naval history to a wide audience of readers and who was nationally recognized for his work during his lifetime has been almost totally forgotten 63 years after his death. This historian made important contributions to the U.S. Naval Institute, the Naval Historical Foundation, the Carnegie Institution, and the Johns Hopkins University, among others, yet none of them has even a photograph by which to remember him. Who was this man whose works can still be read with profit but whose image virtually eludes us? His name was Charles Oscar Paullin. 1
