"Today, the use of blood and blood derivatives in the delivery of medical and surgical care is so extensive that its provision involves a multi billion dollar industry. Yet, as little as sixty years ago the use of blood in medicine and surgery was an infrequent occurrence restricted to occasional transfusions made directly from donors to patients. A dramatic change took place within the space of a single decade - from 1940 to 1950. This was prompted by the pressures and demands of a world conflict that led to the response by Edwin J. Cohn and his associates for blood products to treat the wounded in World War II." "Edwin J. Cohn and the Development of Protein Chemistry tells the story of the birth and cradle period of our present-day knowledge of protein chemistry and of blood and blood derivatives."--BOOK JACKET.
