Reflections on Cellular Physiology as a Catalytic Framework for Medicine

These are the reflections of a retired physician who was introduced to cellular physiology in 1947 at the University of Pennsylvania. I majored in Zoology. I took the required major courses, which were interesting but not exciting. I was a premedical student at the time. Fortunately I was introduced to cellular physiology in 1947. The teacher was Professor Louis Heilbrunn, an amazing man dedicated to teaching and the love of his students. He had a number of graduate students at the time. The undergraduates were well integrated with these advanced students. We used his textbook of physiology and we were all proud of being his students. He gave us a new way of thinking about biology. It was exciting and we were treated as mature students. J. Cell. Physiol. 9999: 2596–2597, 2015. © 2015 The Authors. Journal of Cellular Physiology Published by Wiley Periodicals, Inc.
