1878–1971
A pioneering American physiologist, this early twentieth-century researcher helped shape the study of human metabolism and respiratory exchange. His work with Francis G. Benedict made complex measurements of energy use in the body more precise and influential.

by Francis Gano Benedict, Thorne M. (Thorne Martin) Carpenter
Working in nutritional physiology and metabolism, Thorne Martin Carpenter published important scientific studies on how the human body uses energy, especially during rest and food intake. He is best known for collaborative research with Francis G. Benedict, including The Metabolism and Energy Transformations of Healthy Man During Rest, Food Ingestion and Energy Transformations, and Respiration Calorimeters for Studying the Respiratory Exchange and Energy Transformations of Man.
Records from Project Gutenberg and library catalogs show that his books focused on respiration calorimetry, respiratory exchange, and the measurement of metabolism. A later biographical sketch indexed in PubMed also confirms his lifespan as 1878 to 1971.
Though not a household name today, his work belongs to the foundation of modern metabolic research, helping later scientists study nutrition, physiology, and human energy balance with greater accuracy.
