Lewis S.C. Smythe

Lewis Strong Casey Smythe (pronounced "Smith"; January 31, 1901 – June 1, 1978) was a sociologist and an American Christian missionary to China who was present during the Nanjing Massacre.

Born in Washington, D.C., the son of Lewis Strong Smythe (of DeRuyter, New York) and Annie Amelia Casey (of New Brunswick, Canada), Smythe spent most of his early life in Great Falls, Montana where he finished high school and worked on a cattle ranch. During his undergraduate studies he met Margaret "Mardie" Lillian Garrett, an American born in Nanjing, China, to missionary parents; – Margaret "Peggy" Ann (1931 – 2016) and E. Joan (1934 – 1963). Smythe enrolled at Drake College in 1918, where he received his Bachelor of Science in Law and BA degrees in 1923. In August 1928, he earned a Ph.D. (Department of Christian Theology and Ethics, Chicago Divinity School) for his dissertation "Bibliographic Details Changes in the Christian Message for China by Protestant Missionaries". He was also influenced by and affiliated with faculty from the University of Chicago's prestigious Chicago School (sociology), notably Ernest Burgess and Robert E. Park.

In 1928, the Smythes were dispatched to Nanjing (Nanking) by the United Christian Mission Society (Indianapolis, Indiana). Smythe served as Professor of Sociology at Nanking University (1928 – 1951) served as a medical missionary.

Smythe was in Nanjing during the Battle of Nanking and its aftermath, the Nanjing Massacre. In that role, he and the Committee's chairman, John Rabe, recorded the atrocities committed by Japanese troops and made daily reports complaining to the Japanese embassy. Smythe reported that while the Japanese embassy continually promised to do something about the atrocities, it was not until February 1938 that anything substantive was done to restore order to the city.

After the end of World War II, Smythe was among members of the International Committee for the Nanking Safety Zone who testified about the Nanjing Massacre to the International Military Tribunal of the Far East.

The Smythes were forced by the Communists to leave China in 1951. During a one-year sabbatical (1957 – 1958), he served as the Assistant to the President of Silliman University (Dumaguete, Philippines)

In the documentary film Nanking, Smythe was portrayed by actor Stephen Dorff.
