Seo Jae-pil (1864-1951), known in English as Philip Jaisohn, was a Joseon official, Enlightenment-faction politician, journalist, independence activist and physician. Courtesy name Yungyeong, pen names Songjae and Ssanggyeong, he was born in Dongbok (now Boseong), Jeolla, and raised in Nonsan, Chungcheong. Wikipedia and similar sources give his clan seat as Daegu (some sources write Dalseong, so check the genealogy). His father was Seo Gwang-hyo, and he is said to be an eighth-generation descendant of Seo Jong-je, father-in-law of Yeongjo.
He passed the 1882 special examination and began as Bu-jeongja at the Gyoseogwan, and in 1883 received short military training in Japan at Keio and the Toyama army school. In 1884 he took part in the Gapsin Coup with Seo Gwang-beom and others; after it failed he fled via Japan to the United States, becoming the first Korean US citizen in 1890 while studying medicine.
Returning in 1895 as adviser to the Privy Council, he founded Korea's first private newspaper, the Independent, in April 1896 and the Independence Club that July, introducing democracy and suffrage through debates and lectures. After the government forced him out, he practiced medicine in the United States and supported the independence movement after the March 1st Movement. After liberation he returned at the request of the US military government as chief adviser, went back to the United States in 1948, and died in 1951. He was posthumously awarded the Order of Merit for National Foundation, Republic of Korea Medal, in 1977, and his remains were brought to the Seoul National Cemetery in 1994.
