John I. Lacey (1915-2004).

John I. Lacey died on June 27, 2004. He was one of the pioneers in the integration of psychology and physiology. He worked to establish concepts that cut across disciplines -- eschewing specialization within a cross-disciplinary area. Although a guiding figure in the founding of the Society for Neuroscience, John remained very active in the American Psychological Association (APA) and the Society for Psychophysiological Research until his professional retirement. John's career was characterized by a focused search for specific mechanisms defining how psychological processes interact with physiological processes. John Lacey has left us a legacy of a scientific approach that focuses directly on the relation between psychological concepts and their realization in physiological function. His creativity and breadth of knowledge contributed mightily to the currently burgeoning fields of neuroscience and behavioral medicine. His approach reminds us to continue to include solid psychological science when venturing into these fields.
