A History of Modern Immunology: A Path Toward Understanding describes, analyzes, and conceptualizes several seminal events and discoveries in immunology in the last third of the 20th century, the era when most questions about the biology of the immune system were raised and also found their answers. Written by an eyewitness to this history, the book gives insight into personal aspects of the important figures in the discipline, and its data driven emphasis on understanding will benefit both young and experienced scientists.
