Quotations for Today | |
"The native hospital in Tunis was the focal point of my research. Often, when going to the hospital, I had to step over the bodies of typhus patients who were awaiting admission to the hospital and had fallen exhausted at the door. We had observed a certain phenomenon at the hospital, of which no one recognized the significance, and which drew my attention. In those days typhus patients were accomodated in the open medical wards. Before reaching the door of the wards they spread contagion. They transmitted the disease to the families that sheltered them, and doctors visiting them were also infected. The administrative staff admitting the patients, the personnel responsible for taking their clothes and linen, and the laundry staff were also contaminated. In spite of this, once admitted to the general ward the typhus patient did not contaminate any of the other patients, the nurses or the doctors. I took this observation as my guide. I asked myself what happened between the entrance to the hospital and the wards. This is what happened: the typhus patient was stripped of his clothes and linen, shaved and washed. The contagious agent was therefore something attached to his skin and clothing, something which soap and water could remove. It could only be the louse. It was the louse." - Charles-Jules-Henri Nicolle, French bacteriologist who received the 1928 Nobel Prize for Physiology or Medicine for his discovery (1909) that typhus is transmitted by the body louse (born 21 Sep 1866) "According to my views, aiming at quantitative investigations, that is at establishing relations between measurements of phenomena, should first take place in the experimental practice of physics. By measurement to knowledge (door meten tot weten) I should like to write as a motto above the entrance to every physics laboratory." - Heike Kamerlingh Onnes, 1913 Nobel prize winner in physics for low-temperature research (born 21 Sep 1853) "Quinquies exscriptus, maneat tot millibus annis. (I wrote it out five times, may it last the same number of millennia.)" Final line of his Ars magna - Gerolamo Cardano, Italian physician, mathematician, first to clinically describe typhus fever (died 21 Sep 1576) | |
