DRESSLER, WILLIAM (1890–1969), U.S. cardiologist and electrocardiographer. Born and educated in Austria, Dressler went to the United States as a refugee in 1938. From that year until 1967 when he became consultant, Dressler served as chief of the Cardiology Clinic and head of the Electrocardiographic Laboratory at Maimonides Medical Center. Dressler's major contribution to medicine was his recognition and description of the post-myocardial infarction syndrome, also known as the Dressler syndrome. He wrote six cardiology texts, three in German and three in English. His Clinical Cardiology (1942) became the classic book of cardiological diagnosis.
