R. H. (Russell Henry) Chittenden

Born in 1856 and educated at Yale, Russell Henry Chittenden spent much of his career there as a chemist and teacher. He is widely remembered as a founder of American biochemistry, helping bring laboratory methods and physiological chemistry into a more modern, research-driven form.

His work focused heavily on nutrition, digestion, and the body's use of protein. Chittenden became well known for studies that challenged common ideas about how much protein people need, and his research made him an important voice in early scientific discussions of diet and metabolism.

He remained closely associated with Yale for decades and died in 1943. Today, he is still noted both for his own experiments and for helping shape biochemistry as an academic discipline in the United States.
