Itō Genboku

Itō Genboku (伊東 玄朴) was a Japanese surgeon and Rangaku expert living during the late Edo period and early Meiji era. He was the first surgeon to give a cowpox vaccine in Japan, between 1858 and 1860.

Itō Genboku's offices were later expanded into the foundations of the incipient University of Tokyo Institute of Medical Science.
