William Thomas Perkins, Jr. (August 10, 1947 – October 12, 1967) was a United States Marine who posthumously received the United States' highest military decoration for valor — the Medal of Honor — for his heroic action on October 12, 1967 during the Vietnam War in which he smothered an exploding grenade with his body to save the lives of three fellow Marines. Perkins is the only combat photographer to have received the Medal of Honor.
