Born in 1900 in the USA, Anna Wallis was from Lawrence County, Arkansas. She graduated from Scaritt College for Christian Workers in Nashville, Tennessee, and then went to Korea as a Methodist missionary. She married Suh Kyoon Chul, a Korean schoolteacher. When the North Koreans took Seoul after the start of the Korean War, she became a radio propagandist for the North Koreans and against troops from Allied nations. Her job was to undermine the morale of opposing forces. She did this by announcing the names of captured and killed US servicemen, mocking Black-American troops for their lack of civil rights, and warning new arrivals to the war zone. She was known by American troops as "Seoul City Sue". A few days before US forces retook Seoul the Suhs evacuated to the north. She remained in North Korea until her death in 1969.
