This book, by James Ewing, was bought for the NIH when it was still singular (National Institute of Health) and located on Navy Hill in downtown Washington, D.C. Ewing was the first director of pathology at Memorial Hospital in New York, which was the first cancer center in the United States.
The book was bought for the NIH by Dr. Wilton Earle, who was responsible for the development of many tissue culture techniques. Potter may have used Willis’ book as inspiration for a manuscript that he was working on when he died about the history of plasma cell tumor research.
This book was edited by Michael Potter, Joseph H. Nadeau (Jackson Laboratories, Bar Harbor, Maine), and Michael P. Cancro (University of Pennsylvania School of Medicine, Department of Pathology), from papers presented at a 1985 workshop in Bethesda on the use of wild mice in a wide variety of research.
