Yun Po-sun
Yun Po-sun (Korean: 윤보선, pronounced [junbosʌn] or [jun] [posʌn]; August 26, 1897 – July 18, 1990) was a South Korean politician and activist who served as the second president of South Korea from 1960 to 1962. He was the only president of the short-lived Second Republic of Korea, and served as little more than a figurehead due to its nature as a parliamentary system.
