Frieda Mae Green Hardin (September 22, 1896, Eden Valley, Minnesota – August 9, 2000, Livermore, California) joined the U.S. Navy at the end of World War I in 1918, enlisting, against her parents' wishes, at the age of 22 in Portsmouth, Ohio. In March 1917, with America's entry into World War I imminent, Navy Secretary Josephus Daniels called on women to enlist in the Naval Reserve to free sailors for combat duty. Hardin joined the Navy at a time when women were still denied the right to vote.
