title: James Paget Henry--a retrospective.
abstract: James Paget Henry really began his productive research career at the outset of the second world war. His studies of acceleration and the anoxia of high altitude were supported by the development of then new techniques of measuring and recording critical physiologic parameters such as vascular pressures, respiratory functions and haemoglobin saturation. His inquisitive mind made productive use of the instruments that had to be made by skilled instrument makers working in university shops. Much of this instrumentation has now found its way into the clinical arena where it is now the main armamentarium of cardiac diagnostic and respiratory function laboratories. His work in the space program preceeded that of the Russians but did not get recognition until Sputnik awakened the world to the possibilities of space flight. His development of the concept of a cardiovascular basis for fluid volume control and the supportive investigative work undertaken constitute a milestone in the annals of experimental physiology. The chimpanzees used in Project Mercury were found to be hypertensive which was related to the method of capture used by the commercial suppliers. This lead Jim to study the effect of early experience on resting blood pressure, an effort that soon developed into provocative studies of the biological basis of the stress response.
