John Pappenheimer’s work in capillary permeability and molecular sieving are classics in physiological literature. He contributed valuable research to a wide range of disciplines within physiology: capillary permeability, respiratory physiology, blood-brain CSF transport, the neurochemical aspects of sleep, and most recently to the understanding of the absorption of sugars and amino acids in the intestine. Born in NYC, Pappenheimer attended the Lincoln and Loomis schools. He received a BS from Harvard College and a PhD from Clare College, Cambridge, England. In 1953 he was awarded the lifetime Career Investigator position from the American Heart Association for his work on capillary permeability and in respiratory physiology. He was appointed the George Higginson Professor at Harvard Medical School in 1969. He was a member of the American Physiological Society (President 1964-1965), the Academy of Arts and Sciences, the National Academy of Sciences and Honorary Member of The Physiological Society. He published numerous articles of original work over a span of 70 years. He collaborated with colleagues from around the world, including Frank Winton, Glen Millikan, Bjorn Folkow, Manfred Karnofsky, JM Krueger, J Madara and Charles Michel.
