Early one morning, a mother went in to wake up her son.
"Wake up, son. It's time to go to school!"
"But why, Mom? I don't want to go."
"Give me two reasons why you don't want to go."
"Well, the kids hate me for one, and the teachers hate me also!"
"Oh, that's no reason not to go to school. Come on now and get ready."
"Give me two reasons why I should go to school."
"Well, for one, you're 52 years old. And for another, you're the PRINCIPAL!"
Paul EhrlichDied 20 Aug 1915 at age 61 (born 14 Mar 1854). German medical scientist whose pioneering work in chemotherapy included the discovery of Salvarsan (arsphenamine), the first effective treatment for syphilis against the spirochete Treponema pallidum. His research in the histology of the blood established hematology as a field. Ehrlich also developed new staining methods for microscopic studies on live tissue. At a time when little was understood about the mechanism of disease caused by bacteria, he proposed the side-chain theory as a chemical explanation of immunity, the body's defenses against infection. Though broadly incorrect, the theory nevertheless stimulated further work on the problem. He shared the 1908 Nobel Prize for Physiology or Medicine with Russian bacteriologist, Élie Metchnikoff. |
