Meyer Friedman

Meyer Friedman was an American cardiologist and researcher best known for co-developing the influential Type A and Type B personality theory, which linked behavioral patterns to coronary heart disease. His pioneering work in psychosomatic medicine and behavioral cardiology challenged the purely physiological understanding of heart disease and had a profound impact on both medical practice and public health awareness. Throughout his long career, primarily at the Harold Brunn Institute of Mount Zion Hospital in San Francisco, he authored numerous scientific papers and popular books, cementing his legacy as a key figure in preventive medicine.

Early life and education

Born in Kansas City, Missouri, he was the son of a successful merchant. He pursued his undergraduate studies at the University of Michigan, graduating with a degree in zoology in 1931. He then earned his medical degree from the prestigious Johns Hopkins School of Medicine in 1935, completing his internship at the University of Pennsylvania Hospital. His early medical training was followed by a residency in internal medicine at the Henry Ford Hospital in Detroit, where he first developed a strong interest in cardiology and the emerging field of psychosomatic research.

Career and research

In 1939, he joined the staff at Mount Zion Hospital in San Francisco, where he would spend the remainder of his professional career. He founded and directed the Harold Brunn Institute for cardiovascular research at that institution. His early research focused on the physiology of angina pectoris and the effects of digitalis. A pivotal moment came in the mid-1950s when he and his colleague, Ray Rosenman, began observing the behavioral characteristics of their male patients with coronary artery disease, noting a recurring pattern of intense time urgency, competitiveness, and hostility. This clinical observation launched a decades-long research program investigating the connection between behavior and cardiovascular health.

Type A and Type B personality theory

In 1959, Friedman and Rosenman first formally described the Type A and Type B personality theory in a presentation to the American Heart Association. They characterized the Type A personality as involving excessive competitive drive, chronic time urgency, impatience, and free-floating hostility. In contrast, the more relaxed Type B personality was defined as lacking these aggressive behavioral traits. Their landmark prospective study, the Western Collaborative Group Study, published in the 1970s, provided strong epidemiological evidence that Type A behavior was an independent risk factor for myocardial infarction, comparable to hypertension and hypercholesterolemia. This work was popularized in their 1974 best-selling book, Type A Behavior and Your Heart, bringing the concept to a global audience and influencing fields from corporate wellness to clinical psychology.

Later work and legacy

Following the widespread acceptance of his theory, he later refined his focus to the component of hostility as the most toxic element of Type A behavior. He developed therapeutic interventions, including the Recurrent Coronary Prevention Project, to modify these harmful behaviors in post-heart attack patients. His later books, such as Treating Type A Behavior and Your Heart, detailed these behavioral modification techniques. While some aspects of the Type A construct were later debated within the American Psychological Association and the broader scientific community, his work fundamentally established behavioral cardiology as a legitimate discipline. His contributions are recognized by awards from the American College of Cardiology and the Society of Behavioral Medicine.

Personal life

He was married to Rhoda L. Friedman, a psychiatric social worker who collaborated with him on some of his research and writings. The couple had three children. An avid collector, he maintained a significant private collection of rare books and manuscripts related to the history of medicine and science. He remained professionally active well into his later years, continuing to write and conduct research from his base in San Francisco until his death from congestive heart failure in 2001.
