Robert Harper Shumaker is a graduate of the United States Naval Academy who went on to serve as rear admiral and naval aviator in the U.S. Navy. Shumaker is best known for his resilience as a prisoner during the Vietnam War, and for coining the phrase ‘Hanoi Hilton,’ in reference to the notorious North Vietnamese prison. During his captivity, Shumaker was instrumental in the implementation of the ‘tap code’ that the prisoners used to communicate with each other. After eight years of captivity, on February 12, 1973, he was finally released. After returning home to his family and country, he continued to serve in the Navy until he retired in 1988.
