72059 Heojun           Discovered 2000 Dec. 21 by Y.-B. Jeon and B.-C. Lee at Bohyunsan Optical Astronomy Observatory.
Through Donguibogam, a comprehensive oriental medicine textbook, Heo Jun (1539-1615) successfully integrated the medical traditions in Chosun and China. His observation records regarding an epidemic of scarlet fever were some of the earliest and most accurate in the history of medicine.
