Best known for writing practical, influential books about ice cream and dairy production, this American food scientist brought together research, teaching, and industry experience in a way that helped shape modern dairy manufacturing. His work speaks to a moment when food science was becoming a serious, fast-growing field.

by Grover Dean Turnbow
Born in 1892 and later graduating in agriculture from the University of Idaho, he built a career around dairy science and food production. By 1949, the university recognized his accomplishments with an honorary Doctor of Science degree, and a university record from that ceremony identifies him as president of the International Dairy Association.
He is most closely associated with books such as Ice Cream: A Textbook for Student and Manufacturer and The Ice Cream Industry, as well as technical publications on butter boxes and the use of fruit in ice cream and ices. Taken together, these works show a writer deeply interested in the practical side of making dairy products better, more efficient, and more consistent.
Turnbow died in 1971. Although not a household literary name, he stands out as one of those highly specialized authors whose books helped train students, guide manufacturers, and document an important chapter in American agricultural and food science history.
