Paul R. Ehrlich (Philadelphia, United States; 1932) completed a bachelor’s degree in zoology at the University of Pennsylvania then went on to earn a PhD in 1957 from the University of Kansas. Two years later, he joined the faculty at Stanford University, where he would spend the rest of his professional career. In 1966, he was appointed as Professor of Biological Sciences at Stanford and in 1977, as Professor of Population Studies.

President of Stanford’s Center for Conservation Biology since 1984, he has over 1,000 publications to his name, including fifty books. Among the awards earned for his professional achievements, he holds the Blue Planet Award, the Distinguished Scientist Award of the America Institute of Biological Sciences, and the Eminent Ecologist Award of the Ecological Society of America. He is furthermore a Fellow of the American Association for the Advancement of Science and of the UK’s Royal Society and a member of the U.S. National Academy of Sciences.

Paul R. Ehrlich received his Ph.D. from the University of Kansas. Co-founder with Peter H. Raven of the field of coevolution, he has pursued long-term studies of the structure, dynamics, and genetics of natural butterfly populations. He has also been a pioneer in alerting the public to the problems of overpopulation, and in raising issues of population, resources, and the environment as matters of public policy. Professor Ehrlich's research group covers several areas. It continues to study the dynamics and genetics of natural populations of checkerspot butterflies (Euphydryas). This research has applications to such problems as the control of insect pests and optimum designs for nature reserves.

A central focus of his group is investigating ways that human-disturbed landscapes can be made more hospitable to biodiversity. This work in "countryside biogeography" is under the direction of Professor Gretchen Daily, founder of the field, and Director of the CCB. The Ehrlich group's policy research on the population-resource-environment crisis takes a broad overview of the world

Paul Ehrlich

German physician and scientist (1854–1915)

For other people named Paul Ehrlich, see Paul Ehrlich (disambiguation).

Paul Ehrlich (German:[ˈpaʊlˈʔeːɐ̯lɪç]^ⓘ; 14 March 1854 – 20 August 1915) was a Nobel Prize-winning German physician and scientist who worked in the fields of hematology, immunology and antimicrobial chemotherapy. Among his foremost achievements were finding a cure for syphilis in 1909 and inventing an important modification of the technique for Gram staining bacteria. The methods he developed for staining tissue made it possible to distinguish between different types of blood cells, which led to the ability to diagnose numerous blood diseases.

His laboratory discovered arsphenamine (Salvarsan), the first antibiotic and first effective medicinal treatment for syphilis, thereby initiating and also naming the concept of chemotherapy. Ehrlich introduced the concept of a magic bullet. He also made a decisive contribution to the development of an antiserum to combat diphtheria and conceived a method for standardising therapeutic serums.^[1
