Robert H. Herman (December 19, 1925 – December 25, 1980) was an American author, biochemist, nutritionist, physician, soldier, and scientist. Herman was a gastroenterologist and expert in human nutrition with interests in food intolerance, gastrointestinal enzymes, inborn errors of metabolism, metabolic control, and lactase deficiency. Education Herman earned a Bachelor of Science degree from the Illinois Institute of Technology, a Medical Doctor degree from the University of Illinois College of Medicine in Chicago, and served his medical internship at Walter Reed Army Medical Center in Washington D.C. Herman was married to Yaye F. Tokuyama Herman, his lifetime scientific collaborator, who he met while both were students at the University of Chicago and she was a member of the Women's Army Corps. Military service Herman served in World War II as an enlisted person for two years, and spent most of his life on active duty in the United States Army Medical Corps. He played an important role in the development of one of the most advanced military nutrition and metabolism medical research units of its time, the U.S. Army Medical and Nutrition Research Laboratory, first at Fitzsimmons Army Medical Center in Aurora, Colorado, and later at the Letterman Army Institute of Research of the Letterman Army Medical Center in San Francisco California. At the Letterman Army Institute of Research, Herman held the rank of Colonel in the US Army and served as the Director of the Department of Medicine. Theoretical biology In 1980, Herman edited Principles of Metabolic Control in Mammalian Systems with co-authors Robert M. Cohen and Pamela D. McNamara of the University of Pennsylvania. In chapter one, entitled The Principles of Metabolic Control, Herman advanced the following five "Fundamental Theorems of Theoretical Biology." "The basic principles of chemistry and physics govern the chemical reactions and related processes that occur within the cell." "...the sequential acquisition of biological function by proteins and nucleic acids is a reflection of the evolutionary sequence of development." "...the continued synthesis and degradation of proteins and enzymes constitutes the life process by enabling the metabolic network to achieve negative entropy and remain in a far-from-equilibrium condition." "...all disease is a consequence of at least one abnormality of at least one of biochemical function." "...psychiatric disorders and mental illness have a biochemical basis, however poorly understood." These theorems were discussed in the chapters in the book, including the final chapter written by Herman and Robert
