First World War

The First World War acted as a catalyst for the rapid development of blood banks and transfusion techniques. Inspired by the need to give blood to wounded soldiers in the absence of a donor, Francis Peyton Rous at the Rockefeller University (then The Rockefeller Institute for Medical Research) wanted to solve the problems of blood transfusion. With a colleague, Joseph R. Turner, he made two critical discoveries: blood typing was necessary to avoid blood clumping (coagulation) and blood samples could be preserved using chemical treatment. Their report in March 1915 to identify possible blood preservative was of a failure. The experiments with gelatine, agar, blood serum extracts, starch and beef albumin proved useless.
