Dr. Allen, the first Protestant missionary to Korea, had an opportunity of saving the life of queen’s nephew shortly after his arrival in Korea in 1884. In gratitude the King established the Royal Korean Hospital(Jejoong Won), the first hospital in Korea, and appointed Dr. Allen in charge of the medical affairs of the hospital. After Dr. Allen’s resignation from the mission, the work was successively carried on by Drs. JW Heron, RA Hardie, CC Vinton and OR Avison, the last of whom arrived in 1893. In 1894 the connection of the Hospital with the Korean Government was severed and the work taken over by the Northern Presbyterian Mission, since then it has been a distinctly mission institute. In 1900, while attending the Ecumenical Conference of Foreign Missions in Carnegie Hall, New York, Dr. Avison made the acquaintance of an philanthropist LH Severance, who made a gift of $10,000 for a new hospital. This building, the first modern hospital in Korea, was opened and dedicated in 1904. It was named the Severance Hospital. As the new hospital was built, the old hospital building was to be returned to Korean Government according to the agreement made in 1894. On retaking the old hospital, the Korean Government paid 30,289.99 won for the renovation of the original building and new buildings established in the site during the period of Avison’s entire charge of Jejoong Won. The old hospital building was used as an official residence for a diplomatic adviser Stevens, who was assassinated for his pro-Japan activities. and as a social club for Japanese officials.
