Civilization has never appeared to a better advantage than in the building of her defences against the westward invasion of cholera. There have been times within two decades of the present when in the countries east of the Red Sea 3000 people have died daily of the Asiatic plague. Egypt has been ravaged. The ports of the Mediterranean have been successfully invaded. Commerce, reckless of everything except her own interests, has taken the infection on shipboard, and sailed with it to foreign lands, as though it were a precious cargo! Importers, anxious for merchandise, have stood ready to receive the plague, and plant it without regard to consequences. But in the midst of all this, a new power has arisen in the world, and standing with face to the east, has drawn a sword, before the circle of which even the spectral shadow of cholera has quailed and gone back! Humanity might well break out in rhapsody and jubilee over this great victory.
Among the personal agencies by which cholera has been excluded from Europe and America, first and greatest is Dr. Robert Koch, of Berlin. He, more than any other one man, has contributed to the glorious exemption. Dr. Koch, now by the favor of his Emperor, Baron Koch, is one of those heroic spirits who go before the human race exploring the route, casting up a highway and gathering out the stones. Thus shall the feet of the oncoming millions be not bruised and their shouts of joy be not turned to lamentation.
Robert Koch was born at Klausthal, in the Hartz mountains, on the eleventh of December, 1843. He is a German of the Germans. In his youth he was a student of medicine at Göttingen, where at the age of twenty-three he took his first degree. He was by nature and from his boyhood a devotee of science. For about ten years he practiced his profession, but continued his studies with indefatigable zeal. The investigations of Pasteur had already filled Europe with applause when Koch, following on the same lines of scientific exploration, began to enlarge the borders of knowledge. He became a bacteriologist of the first rank. He began to investigate the causes and nature of contagion; but as late as 1876 his name was still unknown in the cyclopædias.
