"Kenneth Scott Latourette (August 6, 1884 – December 26, 1968) was an American historian of China, Japan, and world Christianity. His formative experiences as Christian missionary and educator in early 20th century China shaped his life's work. Although he did not learn the Chinese language, he became known for his magisterial scholarly surveys of the history of world Christianity, the history of China, and of American relations with East Asia.

Latourette was born in Oregon City, Oregon, the son of DeWitt Clinton Latourette and Ella (Scott) Latourette. His mother and father both attended Pacific University in Forest Grove, Oregon, where they graduated in 1878. DeWitt Clinton Latourette was a lawyer in Oregon City. The Latourette family migrated to Oregon in the 1860s; the family's origins are from France where they fled religious persecution as Huguenots and migrated to Staten Island, New York in the 1600s.

In 1904, Latourette was awarded a Bachelor of Science degree from Linfield College in Oregon. He continued his education in New Haven, Connecticut at Yale, earning a BA in 1906, an MA in 1907 and PhD in 1909."
