= Kenneth J. Carpenter (scientist) = Kenneth John Carpenter (May 17, 1923 - October 13, 2016) was a prominent British scholar in the field of nutrient bioavailability, with a particular interest in the history of nutritional research.

Professional Achievements
Dr. Carpenter attended and received a Ph.D. in Nutritional Science from the University of Cambridge in 1948 and became a fellow of Sidney Sussex College at Cambridge in 1956. In 1977 he relocated to the San Francisco Bay Area to take the position of Professor of Experimental Nutrition at the University of California, Berkeley. Dr. Carpenter chaired the department for three years, and retired in 1991 as Professor Emeritus. His research was concerned mainly with the limited bioavailability of nutrients in foods, and particularly of lysine and niacin. He received the Sc.D. degree in 1974, awarded by Cambridge University for his distinguished record of research, and was named a Fellow of the American Society for Nutrition in 1990.

Dr. Carpenter wrote four books on the historical development of nutritional science, include Pellagra (1982), The History of Scurvy and Vitamin C (1986 ISBN-13: 978-0521320290), Protein and Energy: a Study of Changing Ideas in Nutrition (1994 ISBN-13: 978-0521452090) and Beriberi, White Rice and Vitamin B (2000 ISBN-13: 978-0756763848).

He was a contributor to many publications on the topic of human nutrition, including Encyclopedia Britannica, Journal of Nutrition, and the Oxford Companion to the History of Modern Science. Dr. Carpenter was also a public defender of the use of animals in scientific research and unafraid to be critical of fellow scientists' research methods and conclusions.

The USDA called Dr. Carpenter “…a distinguished scholar of the history of nutrition with a particular interest in the work of W.O. Atwater and the pioneer generation of nutritional scientists.” Dr. Carpenter was awarded the Atwater Medal by the USDA in 1993 for his contribution to the field of human nutrition. Dr. Carpenter gave the keynote address entitled "The Life and Times of W.O. Atwater (1844-1907)."
