Frank Norman Wilson (19 November 189011 September 1952) was an American cardiologist known primarily for his contributions to electrocardiography. Early life He was the only child of Norman Orlando Wilson, a farmer, and Mary Holtz Wilson. He studied at the University of Michigan in Ann Arbor, first graduating with a bachelor of Science degree in 1911, later graduating with a medical degree in 1913 from the same university. Medicine “Our modern understanding of the electrocardiogram comes, in large part, from the lifelong research and teaching of Frank Norman Wilson. In his prime, Wilson dominated used of the electrocardiogram as only two men, Thomas Lewis and Willem Einthoven. Dr. Wilson's outstanding work was paid tribute during the year of his 60th birthday well before his death. The July 1950 edition of the American Heart Association (Circulation) was dedicated to Dr. Wilson. He also received the Gold Heart Medal of the American Heart Association at the time of their annual meeting in 1951. Few investigators have done more to provide a firm foundation in a field of scientific endeavor than did Dr. Wilson in the field of electrocardiography. All of his work in this domain was done primarily in an effort to explain why certain changes appear in electrocardiograms under particular circumstances, and never was he satisfied with the purely descriptive approach that had been used so often in electrocardiographic research. Although some of his work, particularly early studies, were concerned with the cardiac arrhythmias and other allied subjects, much of his research was devoted to study of the ventricular complex, and his contributions in connection with bundle branch block, myocardial infarction, ventricular hypertrophy and abnormalities of the T waves that provide the basis for much of our current knowledge of these conditions. His long familiarity with bio-electric phenomena, his keen and inquiring mind and his ability to use mathematics enabled him to devise the central terminal arrangement and one of the most ingenious and basic conceptions in the field of electrocardiography, the ventricular gradient. Important though Dr. Wilson's papers and tangible contributions have been, his influence as a teacher and as an exponent of the interpretation of electrocardiograms has been of lasting value. His profound knowledge of the electrical phenomena underlying the electrocardiogram made him acutely aware of the many things apart from heart disease that may alter the records, and he often commented that the more a physician knows about
