Prior to [[World War II]] the area within Sampson's boundaries was predominantly farmland but the outbreak of war brought a large need for facilities to train military personnel for the war effort. On May 14, 1942 President [[Franklin D. Roosevelt]] approved construction of a Naval Training Station. The base was named in honor of a local native, Rear Admiral [[William T. Sampson]], from Palmyra, NY, a hero of the Battle of Santiago during the Spanish-American War.
