100 years ago Frank Norman Wilson (Nov. 19th 1890 to Sept II. nd. 1952) was born. Dr. Wilson has been the inaugurator of the modern era of electrocardiography and exponent of the concepts of the significance of changes in the ventricular complex. Wilson demonstrated his theory of the negativity of the ventricular cavity, activated at the endocardial, progressing to the epicardial surface with the inscription of the intrinsic deflection as the impulse arrived as the epicardial surface of the heart. He proved the value of the unipolar exploring electrode with the whole body connected to a central terminal as the indifferent electrode.
