1874–1960
A Seventh Day Baptist missionary and language teacher, he helped English speakers learn spoken Shanghainese in the early 1900s. His surviving work offers a small but vivid window into missionary life and language study in Shanghai.

by Jay William Crofoot, Frank Joseph Rawlinson
Born on May 1, 1874, in Nile, New York, Jay William Crofoot later became a Seventh Day Baptist minister. A memorial notice reports that he died on February 27, 1960, in Plainfield, New Jersey, at age 85.
Crofoot is remembered today mainly for his work on Conversational Exercises in the Shanghai Dialect, a 1915 language guide he prepared with F. Rawlinson. Written as a supplement to earlier Shanghai dialect lessons, the book was designed especially for new missionaries and other foreign learners who needed practical spoken language rather than just reading knowledge.
That makes his work especially interesting for modern listeners and readers: it preserves the everyday rhythm of language teaching in Shanghai during a period of intense cross-cultural contact. While only a limited amount of biographical detail was easy to confirm, the record that survives shows a teacher, minister, and missionary whose writing had a very practical purpose.
