Everyone on this earth has to be grateful to Paul Ehrlich because he made so many advances in medical research. Our life expectancy rate would still be around forty years if Ehrlich hadn"t been interested in chemistry and biology as a young boy. If Ehrlich hadn"t combined so many different chemicals, he would have never combined the chemical known as number 606.

             Ehrlich helped Emil von Behring find an antitoxin for diphtheria. Diphtheria is a disease that particularly affects children and sometimes leads to death. In 1894, mothers no longer had to worry about their child dying of diphtheria because of Ehrlich"s help in the discovery of the antitoxin for the deadly disease.

             Another discovery Ehrlich made was of a dye called trypan red. Trypan red helped destroy cells that caused sleeping sickness. His research of antibodies and understanding how the antibodies attack harmful substances that enter the body has made him the "founder" of modern chemotherapy.

             Ehrlich is best known for his work on curing syphilis. Syphilis is an infectious disease transmitted by sexual contact or kissing. Ehrlich named the compound that cured syphilis "salvarsan". This was a very effective way to cure syphilis. .
