John Hickam
John Bamber Hickam (1914-1970) was an American physician
Hickam was a physician, educator, and medical investigator best known for his leadership in internal medicine and contributions to pulmonary and cardiovascular research. Hickam earned his undergraduate and medical degrees summa cum laude and cum laude respectively from Harvard University. His postgraduate training included residencies at Peter Bent Brigham Hospital and Emory University, followed by service as a U.S. Army physician during World War II.
In 1947, Hickam joined the faculty at Duke University School of Medicine, where his research into pulmonary function in heart and lung disease gained national attention. In 1958, he was appointed Chair of Medicine at Indiana University School of Medicine, a position he held until his death. During this time, he transformed the department into a leading center for cardiovascular research and postgraduate training. He held leadership roles including president of Central Society for Clinical Research; secretary of Association of American Physicians; president of Association of Professors of Medicine; member of NIH Heart Council and AMA committees..
Hickam authored approximately 75 scientific papers, contributed to the Cecil-Loeb Textbook of Medicine, and served on the editorial boards of several major journals. He was a key contributor to the 1964 U.S. Surgeon General’s report on smoking and health. Although widely associated with “Hickam’s dictum”, there is no direct evidence that he coined the phrase himself. Nonetheless, the aphorism reflects his nuanced approach to clinical diagnosis.
