Roger J. Williams, Ph.D. 1893-1988 Hall of Fame 2004 "When in doubt, try nutrition first." Another pioneer in the concept of orthomolecular nutrition was Roger Williams, Professor of Chemistry, discoverer of pantothenic acid (vitamin B5 ), and founder and director of the Clayton Foundation Biochemical Institute at the University of Texas which, under the directorship of Dr. Williams, was responsible for more vitamin related discoveries than any other laboratory in the world. He also developed the concept of Genetotrophic disease. According to Williams, the following thesis formed the basis of this new approach to nutrition: "the nutritional microenvironment of our body cells is crucially important to our health, and deficiencies in this environment constitute a major cause of disease."
