Biography
Walter Reed combined the disciplines of physician and military officer in a career that ultimately transformed public health by confirming that yellow fever is transmitted by mosquitoes. His careful experimentation and willingness to question longstanding assumptions ended the fear that had stalked port cities.
At every turn he stood for scientific rigor, even when the work demanded personal sacrifice, and the lives saved in the tropics and beyond remain a testament to his quiet courage.
