Torii Ryūzō

Ryuzo Torii (鳥居 龍藏; May 4, 1870 – January 14, 1953) was a Japanese anthropologist, ethnologist, archaeologist, and folklorist. Torii traveled across East Asia and South America for his research. He is known for his anthropological research in China, Taiwan, Korea, Russia, Europe, and other countries.

Described by Terry Bennett as "a pioneer in the use of the camera in anthropological field-work," Torii is believed to have inspired researchers, including Ushinosuke Mori, to make use of photography in their research. Torii first made use of a camera while conducting fieldwork in North-East China in 1895.

Later, in the 1900s, Torii was assisted in his research by Mori, who acted as his interpreter.
