Yi Seok (born 3 August 1941) is the nominal King of Joseon as the head of the House of Yi, the Korean royal family. He was described as " the last prince still living on Korean soil, the last pretender to an abolished throne " by The New York Times. Yi gained fame as the " singing prince " with the wedding favorite " Pigeon House ", released in 1967. Since 2004, he has been employed by the city of Jeonju to promote tourism. He is also a professor of history at Jeonju University. He is a son of Prince Yi Kang, the fifth son of Emperor Gojong of Korea, and his thirteenth wife, Lady Hong Chŏng - sun, a former telephone operator. Currently, Yi Seok resides in a building renovated for his use by the city of Jeonju, 243 kilometers south of Seoul. The city government hopes that Seok's settlement on the grounds of its Hanok Village will spotlight the historic significance of the city and help it to attract tourists. As part of this arrangement, Seok gives lectures to Jeonju visitors about Korean history. He also frequently lectures elsewhere and is often called upon for ceremonial duties, despite his official status as a private citizen. Recently, Seok authored a book about the late Joseon Dynasty royal court family and has founded an organization, which he now leads, " The Imperial Grandson Association ", dedicated to preserving the culture of the royal court. The Republic of Korea owned website, Korea.net, recognizes King Yi Seok as the only remaining heir in Korea.
