...Willcm Einthoven, physiological researcher of Leyden University, Holland, went the Nobel Prize for outstanding achievement in Medicine and Physics during 1924. He has invented a device by which the beat of the human heart may be seen, measured, photographed, diseases of the heart detected, its action studied. It was in recognition of this device that the prize was awarded. Dr. Einthoven. genial 64-year-old Dutchman, is now visiting the U. S. He is sprightly, small, with a small grey beard, small grey mustache, wears in his countenance the alert and boyish shyness peculiar to men who have spent their...
Whenever the heart beats, electricity flows over the body's circuit. Dr. Einthoven's device records the fluctuations of this current by means of two wires of quartz, so fine that they are invisible even under a microscope, unless thrown into relief by light against a dark background. These wires are threaded across the magnetic field formed between the polar ends of an electromagnet. In each pole of the magnet is screwed a microscope, one lending light, the other enlargement. Rubber manacles are placed over the wrists of the patient. Under each manacle is a salt pad (electric...
Professor Einthoven's work has been concerned principally with two topics, the application of electricity to the human body, and the study of the electric currents developed by the body...
Professor Einthoven's greatest contribution to science has been the invention of an instrument which enables a photographic record to be made of an electric current as minute as that generated by the heart. He accomplished this by the discovery of the wire galvanometer. This consists of a thin wire, stretched in a magnetic field. By virtue of its ability to measure these feeble electric currents of the heart it has proved a tremendous boon to the study of heart disease. So important is it for this purpose that almost every hospital in the country which takes heart patients...
Professor Einthoven denied the report that he has been awarded the Nobel Prize for research in physiology, declaring that he had had no official notification of any such honor...
