Walter Hollis Eddy

Walter Hollis Eddy was an American educator and scientific writer born in 1877 and died in 1959. Records connected with his published work place him at Teachers College, Columbia University, where he worked in physiological chemistry and wrote on nutrition, vitamins, and health.

His best-known books include The Vitamine Manual, Nutrition, and later works on vitamin deficiency diseases. Writing at a time when the study of vitamins was still taking shape, he helped turn new laboratory findings into books that students and everyday readers could actually use.

Earlier in his career, he also wrote textbooks on physiology and anatomy for schools. That mix of classroom teaching and scientific communication runs through his work, giving it a clear, practical style that still reflects an important moment in the history of nutrition science.
