Exhibition of unreleased photos and other materials at Yonsei University Health System From 29 March to 23 April at the Centennial Hall, Yonsei University Health System is celebrating the 150th anniversary of Oliver R. Avison’s birth and the 125th anniversary of the establishment of Jejungwon (founder, Horace N. Allen) by hosting a special exhibition of photographs and other materials from that time. Oliver R. Avison (1860~1956) transformed Jejungwon—Korea’s first western medical hospital—into the first modern hospital and medical school in Korea. In 1893, with the decline of financial support from the Chosun Dynasty, Jejungwon was confronted with a financial crisis. After Oliver R. Avison became the new hospital director of Jejungwon in November that year, he obtained the concession to manage the hospital; and in 1904, he succeeded in receiving donation from L. H. Severance. With this, Avison reconstructed Jejungwon into the first modern medical hospital in Korea which had also been renamed to ‘Severance Hospital’. He also translated textbooks of anatomy and pharmacology into the Korean language and introduced these medical fields to Korean medical students who were unfamiliar and inexperienced with them at the time. It was in 1908 when Avison’s first seven graduates received the very first doctor’s licenses issued by the Chosun or Korean government. After a close old friend of his and founder of Kyungshin School, Horace G. Underwood, passed away in 1916, Avison took over in charge of Kyungshin School (predecessor of Yonhi College). Until 1934 he was the principal of both Severance Union Medical College and Yonhi College (the two merged into Yonsei University in August 1956). The special exhibition includes new unpublished photos of Avison, medical textbooks which he translated into Korean himself and a farewell book in which 230 political and social celebrities of the time signed when Avison left Korea after retirement in 1935.
