NATIONAL ACADEMY OF SCIENCES J O S E P H E RLANGER 1874—1965 A Biographical Memoir by HALLOW E L L D AVIS Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1970 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. JOSEPH ERLANGER January 5, 1874-December 5,1965 BY HALLOWELL DAVIS OSEPH ERLANGER, Nobel Laureate with Herbert Gasser in 1944, will best be remembered for the epoch-making intro- Jduction into neurophysiology of the cathode ray oscilloscope and the exploration of the electrical activity of nerve fibers. But Joseph Erlanger was also one of the great founders of American physiology in the first quarter of the twentieth century. His stature was already established in cardiac and circulatory physiology before he turned his attention and talents to the electrophysiology of nerves. By then he had already founded the Departments of Physiology at the University of Wisconsin and at Washington University in St. Louis. In his autobiographical reminiscences in the Annual Re- view of Physiology in 1964, he noted that his eminent career was "fraught with a series of fortunate circumstances and for- tunate decisions," but with characteristic modesty he did not mention his rare technical skill as an experimenter, his great ability as a teacher, as organizer, and as a quiet but forceful leader of men, or his mastery of the almost forgotten art of frugality—of accomplishing so much with limited technical support and resources. He was truly one of the pioneers of biological science in America, and he displayed magnificently the spirit and the strength of a pioneer. -

Nobel Laureates with Their Contribution in Biomedical Engineering
NOBEL LAUREATES WITH THEIR CONTRIBUTION IN BIOMEDICAL ENGINEERING Nobel Prizes and Biomedical Engineering In the year 1901 Wilhelm Conrad Röntgen received Nobel Prize in recognition of the extraordinary services he has rendered by the discovery of the remarkable rays subsequently named after him. Röntgen is considered the father of diagnostic radiology, the medical specialty which uses imaging to diagnose disease. He was the first scientist to observe and record X-rays, first finding them on November 8, 1895. Radiography was the first medical imaging technology. He had been fiddling with a set of cathode ray instruments and was surprised to find a flickering image cast by his instruments separated from them by some W. C. Röntgenn distance. He knew that the image he saw was not being cast by the cathode rays (now known as beams of electrons) as they could not penetrate air for any significant distance. After some considerable investigation, he named the new rays "X" to indicate they were unknown. In the year 1903 Niels Ryberg Finsen received Nobel Prize in recognition of his contribution to the treatment of diseases, especially lupus vulgaris, with concentrated light radiation, whereby he has opened a new avenue for medical science. In beautiful but simple experiments Finsen demonstrated that the most refractive rays (he suggested as the “chemical rays”) from the sun or from an electric arc may have a stimulating effect on the tissues. If the irradiation is too strong, however, it may give rise to tissue damage, but this may to some extent be prevented by pigmentation of the skin as in the negro or in those much exposed to Niels Ryberg Finsen the sun. -

CV Joseph Erlanger
Curriculum Vitae Prof. Dr. Joseph Erlanger Name: Joseph Erlanger Lebensdaten: 5. Januar 1874 ‐ 5. Dezember 1965 Joseph Erlanger war ein amerikanischer Neurophysiologe. Sein Hauptarbeitsgebiet waren die Elektrophysiologie und die Physiologie des Kreislaufsystems. Für die Entdeckung der hochdifferenzierten Funktionen einzelner Nervenfasern wurde Erlanger 1944 gemeinsam mit dem Pharmakologen Herbert Spencer Gasser mit dem Nobelpreis für Physiologie oder Medizin ausgezeichnet. Akademischer und beruflicher Werdegang Joseph Erlanger studierte ab 1891 an der University of California, USA. 1895 erwarb er den Bachelor of Science im Fach Chemie in Berkeley. Im gleichen Jahr wechselte er zum Medizinstudium an die Johns Hopkins Medical School in Baltimore, die er 1899 abschloss. Danach war er für ein Jahr im Johns Hopkins Hospital tätig. Bereits zu dieser Zeit beschäftigte er sich mit experimentellen Forschungsarbeiten im Bereich der Neurophysiologie und der Kardiologie. Er entwickelte einen neuen Typ Sphygmomanometer (Blutdruckmessgerät), mit dem sich der Blutdruck in der Oberarmarterie messen ließ. 1901 publizierte er eine Arbeit über das Verdauungssystem von Hunden. Wegen dieser und anderer Leistungen wurde ihm in Baltimore eine Stelle als Assistenzprofessor für Physiologie angeboten, die er annahm. 1902 arbeitete er im Labor des Biochemikers Franz Hofmeister in Straßburg. 1906 erhielt er einen Ruf an die University of Wisconsin in Madison, wo er das Department der neuen Medical School organisierte. 1910 wurde er Professor für Physiologie an der Washington University in St. Louis. Diese Stelle hatte er bis zu seiner Emeritierung im Jahr 1946 inne. Auch danach blieb er wissenschaftlich aktiv.

The room was nearly dark and I was puzzled to hear repeated noises in the loudspeaker attached to the amplifier, noises indicating that a great deal of impulse activity was going on. It was not until I compared the noises with my own movements around the room that I realised I was in the field of vision of the toad's eye and that it was signalling what I was doing."
