twelve books and more than 700 scientific articles. His most noted textbook, Heart Disease, was first published in 1931 and became a classic in the field. His interest in the electrophysiology of the heart would eventually pair him with Drs. Louis Wolff and John Parkinson, who together described the Wolff-Parkinson-White syndrome, a condition of uncontrolled rapid heartbeat. In 1935 he described the electrocardiographic changes of pulmonary embolism. Advocacy work Paul Dudley White is viewed by most medical authorities as the founder of preventive cardiology. Appointed as President Dwight D. Eisenhower's physician following his heart attack in 1955, White very publicly prescribed cycling for his famous patient, giving the bicycle industry a welcome boost. White was a staunch advocate of exercise, diet, and weight control in the prevention of heart disease. In 1924, he was one of the founders of the American Heart Association and became the organization's president in 1941. He was a moving force in the creation of the International Association of Cardiology, and later the International Cardiology Foundation. In 1949, he was named executive director of the National Advisory Heart Council. He was the chief consultant to the National Heart Institute from 1948 to 1955 and was a major impetus in the Framingham Heart Study, which was the first major epidemiologic work to identify risk factors in coronary artery disease. He was also influential in the American Red Cross and in establishing the National Institutes of Health. White received many international honors and was instrumental in establishing cardiology organizations throughout the world, even in the People's Republic of China which he was one of the first American physicians to visit. He also established a connection with Alexander Filipovich Samoilov, a Soviet physiologist who shared White's interest in the electrophysiology of the heart. White was one of the founders of the International Society of Cardiology in 1946, helped to organize its first World Congress of Cardiology four years later in Paris, and presided over the second World Congress in Washington in 1954. White was a staunch advocate of the belief that lifestyle affected coronary artery disease. He was one of the first authorities to recognize that coronary artery disease could occur in young men, writing several papers on the subject. In keeping with his beliefs, he was a vigorous walker and bicycle rider and walked, on one occasion, from Washington National Airport to the White House to consult with
