Paul Ehrlich - in search of the magic bullet

In 2004, we celebrate the 150th anniversary of the birth of Paul Ehrlich, considered the founder of immunology. His life and work can be divided into three creative periods: first, he developed histological staining, then he accomplished his ground-breaking work on immunology, and eventually invented chemotherapy. Paul Ehrlich can be perceived as a man whose success was not the consequence of a will to power, but of his substantial interest in science. (C) 2004 Elsevier SAS. All rights reserved.
