SOME GREAT NAMES IN BIOLOGY 



Pasteur died in 1895 at the age of seventy-three, beloved by 

 his countrymen and honored by the entire world. 



Robert Koch. — Another name associated with the battle 

 against disease germs is that of Robert Koch (k6K). Born in 

 Germany, in 1843, he later became a practicing physician, and 

 about 1880 was called to Berlin to become a member of the sani- 

 tary commission and professor 

 in the school of medicine. In 

 1881 he discovered the germ 

 that causes tuberculosis and 

 two years later the germ that 

 causes Asiatic cholera. His 

 later work was directed toward 

 the discovery of a cure for 

 tuberculosis and for other germ 

 diseases. He died in 1910. 



Lister and Antiseptic Treat- 

 ment of Wounds. — A third 

 great benefactor of mankind 

 was Sir Joseph Lister, an 

 Englishman who lived 1827- 

 1912. As a professor of sur- 

 gery he first used antiseptics in 

 the operating room. By means 

 of the use of carbolic acid and 

 other antiseptics on the surface 

 of wounds, on instruments, and 

 on the hands and clothing of the operating surgeons, germs were 

 prevented from infecting the wounds. This single discovery has 

 done more to prevent death after operations than any other of 

 recent time. 



Modern "Workers on the Blood. — At the present time several 

 names stand out among investigators of the blood. Paul Ehrlich 

 (ar'liK), a German born in 1854, is justly famous for his work on 

 the blood and its relation to immunity from certain diseases. His 

 able research work has given the world a much better understand- 

 ing of acquired immunity and has enabled physicians to fight the 

 dread venereal disease, syphilis, with good results.
