Our History

The division has a long history of bringing together outstanding physicians and researchers who are cited for their national and international contributions to the field.  The Division of Infectious Diseases at Johns Hopkins was founded by Dr. Ivan Bennett in 1958.  Since its inception, the division has established a community where innovative approaches are developed in training, research, and clinical care.  The outcome has been decades of scientific breakthroughs, leaders in the field, and top rated clinical care.

The tradition of excellence in research, training, and clinical care has been continued by each successive division chief below:

Dr. Bennett began to integrate veterinary pathology into the Department, recognizing its key role in the understanding of models of disease. Under Dr. Bennett, the Department became more outward-looking, expanding through diversification of research funding sources and recruitment of outstanding individuals from across the United States and abroad.
