H. Jocelyn Smyly, MA, MB, CHB, BAO, MD (1882-1970) was an Irish medical missionary. He began his work in China in 1912, under the London Missionary, assuming an appointment as associate in medicine at the Peking Union Medical College. In 1928 he was appointed to the chair of clinical medicine at the Shantung Christian University at Cheloo. In Cheloo he became interested in leprosy and subsequently became extremely knowledgeable about many aspects of leprosy. In 1954 he temporarily relieved Dr. Fraser at the leprosy settlement on Hay Ling Chau (which translates as "Island of Happy Healing") near Hong Kong, where he revelled in pathologic investigations and teaching medical students. In 1958 was appointed as Government Leprologist for Northern Rhodesia and retired to England in 1960 where he collaborated with "the Leprosy Research Center," London. He contributed to the second edition of Leprosy in Theory and Practice (1964), and retained a keen interest in all aspects of leprosy throughout his life.
